Read the room. Plenty of people are interested in the aesthetics and the technology.

Thank you! There are many ways to relight Gaussian splats. However, the highest quality results are currently coming from raytracing/path tracing render engines (such as Octane and VRay), with 2D diffusion models in second place. Relig

Thank you! Geometric analysis for Gaussian splatting is a bit like comparing apples and oranges. Gaussian splats are not really discrete geometry, and their power lies in overlapping semi-transparent blobs. In other words, their benefit is

Yes, it's quite trivial to convert traditional CG to Gaussian splats. We can render our scenes/objects just as we would capture physical spaces. The additional benefits of using synthetic data is 100% accurate camera poses (alignm

First, all credit for execution and vision of Helicopter go to A$AP, Dan Streit, and Grin Machine ( https://www.linkedin.com/company/grin-machine/about/ ). Evercoast and Wild Capture were also involved. Second,

I believe most of the "voxel" approaches also require some type of inference (MLP). This limits the use case and ability to finely control edits. Gaussian splatting is amazing because each Gaussian is just a point in space with a

Grin Machine knocked this out of the park! Great job, Chris and crew!

Some companies have a proprietary file format for compressed 4D Gaussian splatting. For example: https://www.gracia.ai and https://www.4dv.ai . Check this project, for example: https://zju3dv.github.io&#x2F

The ghost effect is pretty cool, too! https://www.youtube.com/watch?v=DQGtimwfpIo

There's a ton of fun tricks you can perform with Gaussian splatting! You're right that you can intentionally under-construct your scenes. These can create a dream-like effect. It's also possible to stylize your Gaussian splat

I have. Personally, I'm a big fan of hybrid representations like this. An underlying mesh helps with relighting, deformation, and effective editing operations (a mesh is a sparse node graph for an otherwise unstructured set of data). H

Cool aesthetic!

My wife said the same thing, but it gets better after the intro.

My friend and colleague shared a link with me. Pretty cool to see this trending here. I'm very passionate about Gaussian splatting and developing tools for creatives. And thank you!

For sure!

I think it's because they already had proven capture hardware, harvest, and processing workflows. But yes, you can easily use iPhones for this now.

Aha: https://www.red.com/stories/evercoast-komodo-rig So likely RealSense D455.

I was not involved in the capture process with Evercoast, but I may have heard somewhere they used RealSense cameras. I recommend asking https://www.linkedin.com/in/benschwartzxr/ for accuracy.

Sure! Gaussian splatting is a bit like photogrammetry. That is, you can record video or take photos of an object or environment from many angles and reproduce it in 3D. Gaussians have the capability to "fade" their opacity based o

Gaussian splatting is not NeRF (neural radiance field), but it is a type of radiance field, and supports novel view synthesis. The difference is in an explicit point cloud representation (Gaussian splatting), versus a process that needs to

A drone path would not allow for such seamless transitions, never mind the planning required to nail all that choreography, effects, etc. This approach is 100% flexible, and I'm sure at least part of the magic came from the process of

The aesthetic here is at least partially an intentional choice to lean into the artifacts produced by Gaussian splatting, particularly dynamic (4DGS) splatting. There is temporal inconsistency when capturing performances like this, which ar

Hi, I'm one of the creators of GSOPs for SideFX Houdini. The gist is that Gaussian splats can replicate reality quite effectively with many 3D ellipsoids (stored as a type of point cloud). Houdini is software that excels at manipulatin
