- MattCruikshank 4mo agoI want some math Phds to sit down with the Corridor Crew guys and figure out how to make Gaussian Splat reconstruction way better, the way they came up with CorridorKey.
- carlos-menezes 4mo agoYou might want to throw that one away :)
- p0w3n3d 4mo agoYup. It's rotten on the other side. Or maybe lead poisoned
- dudefeliciano 4mo agonot sure if that's a joke but i think that's just the effect of the strawberry being placed on a glass/plastic surface to be filmed from underneath
- danybittel 4mo agoIt is in fact still on it's mount and slowly rotting / molding.. for a second capture :-)
- josh-wrale 4mo agoSomeone: Please combine microscopy with gaussian splatting.
- Kalendermann 4mo agoThis was also my first thought when I zoomed in into the strawberry. I wonder if you can achieve a microscope like effect with a more suitable setup. E.g. better lighting, zoom, lens, etc.
- danybittel 4mo agoI have done 2x macro (an ant).. and want to try 5x.. but as you get closer, the depth of field becomes really shallow. You can do focus stacking but you risk that the individual areas in focus are less ideal aligned and the tracking can't make any sense out of the geometry anymore.
- jcattle 4mo agoDon't know if this would be in your wheelhouse, but for very nice macro splats, check out the work by Dany Bittel: https://danybittel.ch/macro.html https://danybittel.ch/macro.html For example this bumblebee: https://superspl.at/scene/cf6ac78e https://superspl.at/scene/cf6ac78e Edit: I completely missed that this was posted by him (:
- kridsdale1 4mo agoIncredible that specular highlight isotropy vectors are somehow encoded.
- galsapir 4mo agoFrom the link: "Shot from 90 perspectives, 88 focus stacked images each. Nikon Z8, full frame, f/7.1, exposure 1/160, ISO 100, Laowa 180mm macro lens, with LED light and bluescreen." Insane!
- danybittel 4mo agoAnd it only takes 20 Minutes to shoot all 7920 photos, the Z8 is crazy fast.
- dudefeliciano 4mo agoi made some decent splats (admittedly much lower quality than this) by taking video with my iphone13 mini and then chopping it up into individual frames via ffmpeg
- MattCruikshank 4mo agoWhere's the Lytro camera when you need one? I was really pulling for OTOY to keep making light field capture and display technology...
- danybittel 4mo agoThere is actually still a Lytro type camera for industrial application available: https://raytrix.de/ https://raytrix.de/ Too low res, too expensive for my use case unfortunately.
- mgaunard 4mo agoWhat happened to the bottom of that poor strawberry?
- danybittel 4mo agoIt was mounted at the bottom.. and I can't quite reach it with my camera. Might have to try some two pass way.
- gobdovan 4mo agoMount it on a needle/skewer, it should let you capture it in one pass.
- 4gotunameagain 4mo agoAssuming that the person that did this has not tried that. If you look at the setup photos, the grape is resting on a couple of nails. This suggests that many different things have been tried.
- deleted 4mo ago[deleted]
- CatMustard 4mo agoI wonder would a good, sharp needle and thread make for good mounting for a soft object like this? Thread the needle, pass it right through the strawberry and the secure the thread on something above and below. As long as the strawberry doesn't slide down the thread (hopefully a strawberry is light enough friction would hold it in place!) Anyway, very cool splat, fair play
- danybittel 4mo agoI glue mounted the strawberry on three nails and used pins to secure it. I have to think about your idea.. I don't think friction would be enough to hold it in place.. it would probably be hard to knot the top onto something too, as that's where the light is: https://i.imgur.com/vIjw6pc.jpeg https://i.imgur.com/vIjw6pc.jpeg But I'm always experimenting with the mounting, thanks for the inputs.
- timonoko 4mo agoWhat? KIRI Engine makes splats. I always wondered what 3DGS might mean. Yes. I knoweth what "splats" are: They are splats of fuzzy blobs on the display surface.
- aminekhd 4mo ago[dead]
- brazzy 4mo agoLovely! How was the mechanical setup to ensure that all those shots are consistent, and how long did it take?
- danybittel 4mo agoI posted some pictures.. takes only 20 min!
- a1o 4mo agoCan you show the setup? (Can we do a Gaussian Splat of the setup of the photograph for the Gaussian Splat of the Strawberry?)
- danybittel 4mo agoI just posted some images.. I have actually done my studio, (quality is.. let's say painterly ;-): https://superspl.at/scene/0a3916cd https://superspl.at/scene/0a3916cd
- a1o 4mo agoTHAT IS AMAZING!! Seriously, impressive work! Thanks for the link.
- burningion 4mo agoThe splat of the studio has the perfect amount of detail. It looks like you're streaming from the camera direct to the computer usually? How do you check the progress / quality while capturing? Seeing the (great) results makes me more curious about the process of creating now.
- danybittel 4mo agoThanks! I use the computer only to setup the shot, adjust lighting make test stacks of different angles. If everything is good, I disconnect and capture to the memory stick. During the shooting I only adjust the beginning or end of the rail a bit, so everything is in focus at some point. Triggering (manually) the rotary disk still happens from the computer.
- deleted 4mo ago[deleted]
- svetlins 4mo agoGreat work! There are more awesome splats on the author's profile page: https://superspl.at/user?id=danylyon https://superspl.at/user?id=danylyon
- voidUpdate 4mo agoGaussian splats look really good from a distance, but as soon as you zoom in, they really fall off a cliff :/
- bozdemir 4mo agothis is awesome, I wonder what's under there, looks black, maybe thats where they mounted and rotated the strawberry...
- danybittel 4mo agoYes mounting.. and I can't quite reach all the way from below.
- vessenes 4mo agoDany, this is so cool. I'm wondering if the splat community has decided this paper is valuable -- https://github.com/fraunhoferhhi/Self-Organizing-Gaussians https://github.com/fraunhoferhhi/Self-Organizing-Gaussians -- looking at all the detail in the strawberry splat made me wonder how small one can get the download, and what the current state of the art is for compression.
- danybittel 4mo agoThanks! We have two compressed formats, the sog by PlayCanvas and spz with sparkjs. Both now support LODs and compress really well.
- zokier 4mo agoMy intuition is that in theory focus stacking should not be necessary as preprocessing step for 3dgs (or photogrammetry). Does anyone know if there is any recent developments in this regard? Focus stacking generally is not perfect process and can lead to artifacts/errors and I'd imagine those can then compound when stacked images are used for 3dgs. Also the image focus actually provides some depth data in itself that could be useful?
- KeplerBoy 4mo agoIf you don't focus stack and try to train on partially unfocused images, the optimizer will try to match the rendered view to be also partially unfocused. You would have to mask out the blurry areas for each image. I guess one could just implement a feature where the optimizer only optimizes gaussians within the sharp distances relative to the camera.
- zokier 4mo agoOther way of looking at the question is if you could make focus stacking better by using the full multi-view dataset? Afaik focus stacking essentially does depth estimation so it seems like multiple views would help with that. Another way would be some kind of 4d GS where one dimension is the focus distance. But I'd guess the renders would inherently have shallow depth then, which is less useful usually.
- zardo 4mo ago> Another way would be some kind of 4d GS where one dimension is the focus distance. That seems like the way to do it, someone has to be working on that. searching... https://dof-gaussian.github.io/ https://dof-gaussian.github.io/
- danybittel 4mo agoThis is an interesting question. There has been some attempt to model the camera better than just a pinhole camera, that could work. https://dof-gaussian.github.io/ https://dof-gaussian.github.io/ https://github.com/leoShen917/DoF-Gaussian https://github.com/leoShen917/DoF-Gaussian My take.. at a macro scale, the dof is usually so small, that it's hard to get a reliably track. So you'd need some sort of way to tell that these stacked photos belong into a series, and then you sort of are doing focus stacking :-) I do think the alignment algorithm could be improved. Maybe the approaches I linked could be used to make a much more robust focus stacking algorithm, that also corrects for 3D geometry. That would be really cool!
- deleted 4mo ago[deleted]
- Vinnl 4mo agoI read [1], but I still don't quite know what I'm looking at. My guess is a 3D model reconstructed from lots of detailed pictures? [1] https://en.wikipedia.org/wiki/Gaussian_splatting https://en.wikipedia.org/wiki/Gaussian_splatting
- marceldegraaf 4mo agoThis video explains how Gaussian splatting works: https://www.youtube.com/watch?v=X8yRlA7jqEQ https://www.youtube.com/watch?v=X8yRlA7jqEQ
- StevenNunez 4mo agohttps://youtube.com/watch?v=X8yRlA7jqEQ https://youtube.com/watch?v=X8yRlA7jqEQ is how I learned about them. They're really cool!
- jaccola 4mo agoLots of translucent blobs composited to produce the appearance of a strawberry. There is no mesh or model. The visual surface of the strawberry could be made up of blobs spaced far apart physically and not where the surface appears to be. This is why they are called radiance fields, they model the light not the geometry. Practically the blobs positions/rotations can be constrained to better physically match the geometry of a strawberry.
- KeplerBoy 4mo agoI'm not sure i agree. The blobs are exactly where the surface appear to be because they are constrained by multiple viewing angles. Otherwise the splat would fall apart as soon as the viewing angle is changed slightly (Which it absolutely does in many examples on supersplat, you cannot really create an out of distribution view with 3GS, it's not magic)
- Tade0 4mo agoBeautiful. What I love about gaussian splats is the way they degrade - instead of a hard cutoff or LoD changing spheres into cubes etc., they get increasingly "dreamy" - the basic idea is still there, just less detailed. Take for example this scene: https://superspl.at/scene/e721ea7c https://superspl.at/scene/e721ea7c If you navigate closer to the trees, things around you become blurry - as if the very fabric of reality unraveled.
- scrumper 4mo agoI don't know anything about them but it's a cool effect. At least on this strawberry, you're not zooming in but rather traveling closer. I don't see the increasing (made up) detail you'd expect from a zoom, we sort of pop through the skin into an invented interior.
- danybittel 4mo agoI like that they are sort of between a photo and a 3D model. Nothing quite like it.
- xattt 4mo agoIs there a specific name for this “dreaminess” effect?
- jl6 4mo agoSplattenuation
- acc_297 4mo agoits funny that sky features like clouds and blue patches end up being fit very close to ground level because there isn't a difference in perspective to cue in the algorithm that the skybox should be tall, I wonder if there is any way to incorporate the fitting algorithm with simultaneous lidar data about true distances of things to allow scenes to be viewed from further up
- amelius 4mo agoThat's what Google Street View should be like more.
- ivolimmen 4mo agoWow this is a time killer... ended up here: https://superspl.at/scene/ff1d0393 https://superspl.at/scene/ff1d0393 beautiful!
- data-ottawa 4mo agoIt’s amazing this runs perfectly smooth on my iPhone 12 mini That is indeed a very cool scene being about to wander around and still have decent resolution
- lopsotronic 4mo agoAh the timeless joy of falling through the floor geometry. Seriously though - it's breathtaking. The first guy who figures out the bridge between splats and dynamism - animation, editing, responsiveness - is going to be one of the immortals of 3d design.
- cubefox 4mo agoThere are many ways to represent 3D data, but animations really only work properly with polygon meshes (e.g. triangle surface meshes or volumetric tetrahedral meshes).
- thfuran 4mo agoYou pretty much just need a representation that can be constructed reasonably and interpolated.
- lopsotronic 4mo agoBut the mesh is itself an abstraction, you just need to build that bridge. We've been leaning away from pure polygons for decades, anyway. Vertex skinning, SDFs, volumetrics, simulation, and a lot more. The meshes in a From Software game are for exmple hilariously simple, most of the animation is force simulation to make the famous "frizzles" that they like.
- ramon156 4mo agoImagine if we start designing GPUs around this technology as opposed to vectors. Imagine what voxel engines would look like. Would love a simulated experience or a small scale that theorizes about this.
- ovenchips 4mo agoI built PlayCanvas in 2011 to power video games. Here we are in 2026 and it's powering strawberries.
- dormento 4mo agoThank you for your service! This is one of the most endearing things about open source IMHO, the way people can find novel uses for it.
- ovenchips 4mo agoI completely agree with you. I'm constantly bowled over by the creativity of the SuperSplat/PlayCanvas communities.
- ovenchips 4mo agoFor anybody interested, SuperSplat (and PlayCanvas) is open sourced on GitHub: https://github.com/playcanvas https://github.com/playcanvas
- ImJasonH 4mo agoI'm really interested to see what folks can do with animated Gaussian splats: https://youtu.be/X8yRlA7jqEQ?si=dXeHa03jO7MTBNLA https://youtu.be/X8yRlA7jqEQ?si=dXeHa03jO7MTBNLA The filesize of a 3d animated splat is seemingly very small, and the method enables ~arbitrary FPS. But it seems the setup required to record it is still huge and expensive, which limits its usefulness. Even with that there are some interesting use cases, eg. I'd love to be able to watch concerts this way, and freely move around the stage and crowd from any angle.
- chimpanzee2 4mo agoJust wow! As I scrolled through the website, I was even more impressed with this one though! https://superspl.at/scene/c67edb74 https://superspl.at/scene/c67edb74
- FigmentEngine 4mo agoshame the bishop behind looks a bit flat though ;-)
- MattCruikshank 4mo agoI just wanted to do a quick size comparison... If I'm reading Chrome right, that's 171 MB, for the website, and the data. If I'm doing the math right, that's 40 seconds worth of the bandwidth from Netflix, at its highest rate.
- mkmk 4mo agoBeautiful and quite neat to 'walk' up into the ceiling and look down. Feels like you're either quasimodo or God, depending on how nuts you are.
- ComputerGuru 4mo agoThis one keeps crashing the browser after it reaches 100%. Safari/iOS, iPhone 13. I was able to navigate and use a few of the other ones linked to from the comments, though. Curious.
- busymom0 4mo agoI have the same phone and it crashed for me too after reaching 100%
- bestouff 4mo agoThis doesn't work at all for me (Linux desktop, tried with Firefox and Chrome). I only see "fullscreen-extended blurry thumbnails" of the splats.
- slimbuck 4mo agoIf you can, please check any output/errors on the developer console?

- probably_wrong 4mo agoWorks for me with Firefox 140.10.2esr on Devuan 5.
- evrimoztamur 4mo agoThere is a faint sensation of translucency, I wonder if that's an artefact of the process, or if it's the actual optics of the surface layer if the strawberry...
- vanderZwan 4mo agoWell, at certain angles you actually get very noticeable gaps in the strawberry that are visible when rotating it, but almost invisible when static. I think it's mostly due to that.
- danybittel 4mo agoIt's an artefact unfortunately. Gaussian splats have no concept of refraction and have a hard time dealing with reflection. Highlights, usually so so. Something I always wrangle.
- zokier 4mo agoI wonder if that is somehow related to how you seem to have very strong studio light for the subjects? Somehow the bright light penetrating deeper into the material or something like that
- danybittel 4mo agoThe light doesn't need to be completely flat like what you'd do when scanning it more traditionally, for meshing. The problem is when the highlight is sharp and reflects it's surrounding. You could remove it, with cross polarization.. But then it wouldn't look realistic anymore.
- deleted 4mo ago[deleted]
- sbarre 4mo agoLooking at all the outdoor scenes that you can walk around, I wonder how long until we start seeing this in places like Google Maps/Earth, as a replacement for the low-res 3D renderings we have now. I guess the number of samples required to generate a GS is the constraint now, but maybe that will get solved.
- dudefeliciano 4mo agorendering them is also non trivial from what i understand, since the millions of indivudal point positions need to be recalculated all the time while moving
- kridsdale1 4mo agoTurns out, GPUs are amazing at this.
- jofzar 4mo agoGoogle already has some splats on google maps, https://youtu.be/gXug7Kb3p4I https://youtu.be/gXug7Kb3p4I
- classified 4mo agoImpressive, but my poor GPU is melting :)
- arnabdey0503 4mo agoVery nice. did you segment the images before?
- danybittel 4mo agoYes it's shoot in front of a bluescreen.
- arnabdey0503 4mo agoNice.
- arnabdey0503 4mo agoAny suggestions to capture and reproduce very small details in the object? Something works well for you?
- KeplerBoy 4mo agoCan you elaborate why you chose slang-splat over let's say Lichtfeld studio? How does it compare to the other splat-training tools?
- danybittel 4mo agoI usually use PostShot.. but the quality was not very good. I want to try LichtFeld but my Graphics Card has too little memory.. so I reached out on twitter, some people ran tests and Mykhailo got some better quality out of it so I took his training. You can d/l the COLMAP dataset for free and try yourself.
- KeplerBoy 4mo ago[dead]
- artursapek 4mo agoew the bottom is moldy
- dredmorbius 4mo agoFor those unfamiliar with Gaussian Splatting: <https://en.wikipedia.org/wiki/Gaussian_splatting https://en.wikipedia.org/wiki/Gaussian_splatting>. (I'm ... still not sure what I'm looking at on TFA, and whether or not my browser configuration fails to fully present the site as intended.... OK, if all you're seeing is a blurred image of a strawberry, yes, you'll want to enable a bunch of JS resources. I'm using uMatrix, several hosts must be enabled.)
- karmakaze 4mo agoI like to think of Gaussian Splatting as a stage full of improv actors who are iteratively/concurrently filling details in regions down to pixels until the full picture is painted.
- tantalor 4mo agoReally terrible performance in Chrome, I'm getting between 10-15fps. What's the matter?
- jrflo 4mo agoIt appears to be rendering locally, my fans started spinning up when I was wandering through another image on the site.
- duckerduck 4mo agoMakes me wonder if we'll ever see a video game where the world is created by set designers irl.
- lubesGordi 4mo agoSim racing is at least kind of like that.
- MattCruikshank 4mo agoI know feelings about AI are mixed. But when AI can dream up gaussian splats in real time, from a prompt, and do refinement as you get closer to things... That's going to be pretty bonkers.
- perching_aix 4mo agoThat's kinda what NERFs are (neural radience fields). They actually preceeded this Gaussian story, with Gaussians coming in and outperforming them. Maybe they'll merge later for something even better, I don't know enough about them.
- MattCruikshank 4mo agoSure, but NERFs were trying to match your input photos and poses, not some arbitrary prompt, if I understand correctly.
- Lerc 4mo agoYes they are image generators. You want image generator generators. A diffusion style process generating gausians instead of pixels. You could possibly do nerfs that way, but it would be effectively generating a trained network. If you managed to do that it would have broad application throughout the field of AI.
- dpoloncsak 4mo agoWhat would this look like in practice? A net that outputs weights for a new net to use?
- xigoi 4mo agoCouldn’t you “uncurry” such a process to have only a single network?
- 4mo ago
- buibuibui 4mo agoHow can I start creating Guassian Splat of my environment with my 360 camera? Is it possible to do that with local software?
- Centigonal 4mo agoThis is like a beautiful little miniature. It's cool to see gaussian splatting applied to a detailed small thing versus a big scene. I have a question about perhaps the most boring aspect of this strawberry: the license. you write, "You can download it under CC BY license, but attribution is appreciated rather than required." IANAL, but I'm pretty sure you can't license your work CC-BY and then waive the BY requirement in the description. Rather, you'd have to license it with something more permissive like CC0 and request attribution if you want attribution to be optional. Is that right?
- RobotToaster 4mo agoI'm pretty sure it's allowed, just as saying "do what you want with it" is an informal license, it's just a little pointless.
- danybittel 4mo agoThat's what I thought too.. supersplat has no way to set it to CC0 otherwise.
- CobrastanJorji 4mo agoIt's their content. They can do anything they like. Sort of. There are countries like France where attribution rights are fundamentally inalienable, and the author can always demand attribution, even after forever waiving the right to attribution. But in the US, the party who benefits from a contractual provision can generally choose to ignore or forfeit that provision. Whether it's still called the "CC BY" after that is debatable, since the whole point is attribution, but licensing by the CC BY and immediately waiving that requirement seems legitimate to me.
- weystrom 4mo agoI tried making one, but I couldn't make through the camera position tracking bit, software was super unintuitive. Very interested in gaming applications for this tech, but still waiting for it to be more approachable from a layman's point of view.
- ChadNauseam 4mo agoOne thing you can do with this that works quite well is use it to "decrop" (widen the viewing angle) of a video. This is very useful for stabilization which usually involves cropping. Here's an example: https://x.com/i/status/2051504427287404568 https://x.com/i/status/2051504427287404568 Once they get quicker to train, I expect this to be a popular use of them
- sovok 4mo agoAlso interesting: https://github.com/apple/ml-sharp https://github.com/apple/ml-sharp Apples model to generate Gaussian splats from a single image. Takes about 30 seconds on an M1 Pro. It falls apart once you move too much, but for a little side-wiggling or a second-eye view for VR, it's great. And looks a lot better than the old approach of depth map + vertex shaders that I use in https://github.com/combatwombat/tiefling https://github.com/combatwombat/tiefling. But ml-sharp has 2.6 GB weights, a bit too big to run in the browser.
- RobotToaster 4mo agoAny idea what kind of vram is needed to run this on Nvidia?
- sovok 4mo agoThe Python process peaks at about 15 GB, so maybe a 24 GB GPU works. But others seem to have problems wih Nvidia: https://github.com/apple/ml-sharp/issues/84 https://github.com/apple/ml-sharp/issues/84
- kridsdale1 4mo agoIt runs natively on the Photos app in Vision Pro, which shares 16GB of ram with GPU and CPU.
- mnorris 4mo agoThe smallest Nvidia gpu I've run Sharp on is an Nvidia T4 which I think has 16 GB on the chip
- ben7799 4mo agoIs this thing the basis of what Apple is doing in the Photos app in the most recent OS revisions? It seems to work a lot quicker than 30s now on iDevices and Macs.
- 0xWTF 4mo agoHow did they decide what the inside of the strawberry looks like? Because that seems very incorrect.
- db48x 4mo agoThe flesh of the strawberry is very slightly translucent. By taking images from many angles, you can derive some information about the interior. This is not a separate step, it is simply the optimizer finding splats that contribute the right amount of color and light at various viewing angles. Of course those splats aren’t really going to look right to anyone who has ever eaten a strawberry, because they are only derived from the input images and not your past memories of a real strawberry. You’ll also see the same type of problems in any incomplete part of any scene. Go poke around any of them and you’ll find places where there wasn’t enough information to make a satisfying reconstruction. For example, the back of the moon <https://superspl.at/scene/2ac8f423 https://superspl.at/scene/2ac8f423>, the fridge in the coffee shop <https://superspl.at/scene/6a0c3ccf https://superspl.at/scene/6a0c3ccf>, underneath the footbridge in the forest <https://superspl.at/scene/23ebe85c https://superspl.at/scene/23ebe85c> (or indeed anything in the distance), etc, etc.
- lightedman 4mo agoA Youtuber that records jookin (a mid-South form of dance) uses Gaussian splats for his videos to bring the dancers out into the forefront and hold center stage, it's a neat trick. https://www.youtube.com/watch?v=k0MGoFaIiWs https://www.youtube.com/watch?v=k0MGoFaIiWs - WARNING - heavily adult lyrics and a loud starting "MOTHERFU*AAAAAAS" right off the top.
- hamburglar 4mo agoWhat makes you say this is using Gaussian splats? It looks like simple motion-based cropping to me.
- lightedman 4mo agoBecause I know the video producer and have talked about this in-depth with him.
- evan_ 4mo agoThat doesn’t really look like Gaussian splats to me- but this video, Helicopters by A$AP Rocky, uses the technique well: https://youtu.be/g1-46Nu3HxQ?si=y_u257DzgOg2QV83 https://youtu.be/g1-46Nu3HxQ?si=y_u257DzgOg2QV83
- divan 4mo agoDoes anyone know if it's already possible to build gaussian splat of the person that moves/rotates from the single camera? (I.e. to use sequence of frames to reconstruct occluded parts of the body for other frames)
- thrownthatway 4mo agoI watched this 1 month old video two days ago: https://youtu.be/X8yRlA7jqEQ https://youtu.be/X8yRlA7jqEQ It kinda splatted my mind. As I understand it, Gussian Splats aren’t a method of constructing missing data in the sense you’re asking here. But there are other, well established, methods of generating missing data in convincing manner, that are beyond my field of expertise or interest to be able to repeat here. With the added benefit that if I’m wrong, being wrong can be a great way to spur discussion 8)
- divan 4mo agoThere is definitely some body of research around what I'm asking [1] [2]. Just curious if someone have a good grasp on the current state of it.

- ArekDymalski 4mo agoAs I have learned about Gaussian Splatting just a few weeks ago, I have (perhaps funny/naive/stupid) question: is there any progress or at least theoretical chance to have dynamic lighting?
- aruametello 4mo agoout of the box, I imagine that surfaces can be lit, but probably not shadowed correctly. (structures aren’t solids, more like particles in 3d space) it could look like the real-time lighting of an old game engine on rather modern assets. (quake 2-3 era) or perhaps some "occlusion pre-pass" could be done to create a voxelized sparse volume from the splats that set a "voxel opacity value" for each to absorb light? (not far from how prebaked GI works nowadays) note: not an expert on rendering, just a nutjob that did stuff in opengl in the old days.
- hellohello2 4mo agoThere can be some issues with shadowing yeah, especially if you render with splatting/rasterization, but its fine if you raytrace I think.
- hellohello2 4mo agoThere are some works on doing this directly e.g. https://arxiv.org/abs/2601.23065 https://arxiv.org/abs/2601.23065 but getting accurate materials is a challenge for anything more than diffuse. AI-based relighting will no doubt start working soon.
- wren6991 4mo agoNoting the permissive license, could we be witnessing the birth of a new Utah teapot or Sponza atrium?
- danybittel 4mo agoOh, that would be amazing! The photos are also available and some people definitely take it for a test ride. However.. This dataset with the stacking is far from generic.
- porphyra 4mo agoThat new Laowa 180mm macro lens is amazing. So sharp, free of chromatic aberrations, compact, and I like the long working distance and reduced perspective distortion that the 180mm focal length offers.

- danybittel 4mo agoI also have them on x: https://x.com/DanyBittel/status/2055624819941483005 https://x.com/DanyBittel/status/2055624819941483005 I thought direct image links are more welcomed here.

- varispeed 4mo agoCan't install anything on this particular machine.
- BobbyTables2 4mo agoLooks like it’s already going bad…
- painted-now 4mo agoIt definitely looks impressive. But something looks off: the red area around the "seeds" is pushed towards the center of the strawberry - or that at least the outer most layer is somewhat transparent and some deeper layers are visible.
- danybittel 4mo agoThose are artefacts. Splats are not perfect around reflections.
- monkpit 4mo agoI’m impressed by Gaussian Splatting and I love these kind of demos, but I have a noob question - can they respond to lighting?
- dagmx 4mo agoNot traditional Gaussian splats since they have their lighting baked in but there are alternate forms that have the ability to do so but largely in academia or very specific use cases
- vipshek 4mo agoThis took me down a rabbit hole that led to this company, doing Gaussian splat videos: https://www.4dv.ai/ https://www.4dv.ai/. Fascinating.
- lucb1e 4mo agoIf you just see a blurry image and nothing loads or happens, check the javascript console if it says "WebGL not supported"
- thatxliner 4mo agoit's weird at the bottom

- eckelhesten 4mo agoI’m curious to why not all modern PC/console game developers use this technology to create realistic graphics in their games? If my old phone can render it with fairly high frame rate, I’m sure a full game with realistic graphics would work well on a mid/high end PC.
- steve_adams_86 4mo agoI’m not sure if the same limitations apply today, but when I last looked into it: 1. Lighting is baked in so they don’t fit well in dynamically lit environments 2. Splats aren’t as suitable for bodies you’d animate, like meshes are. They also don’t work well for very thin or sharp surfaces in general 3. Splats are pretty memory-hungry so large scenes would require better hardware than consoles can offer These might not be as true today, and I can’t recall exactly when I read this. Probably 3 years ago or so. I recently read they’re making their way into games, so it’ll happen as the kinks are worked out.
