Wait, you renamed Forge ( https://forge.dev ) released last week by World Labs, a startup that raised $230M. Is this "I worked with some friends and I hope you find useful" or is it "So proud of the World Labs team

IANAL but I assume so. "Employee of a competing company" (whatever that means) isn't a protected class.

Rising rates don't make the dollar stronger. There's no empirical relationship between interest rates and exchange rates.

Yes, although not complete noise – probably empty. Haven't checked but assume there's regularization of the NeRF parameters.

DreamFusion doesn't directly build a 3D model from those generated images. It starts with a completely random 3D voxel model, renders it from 6 different angles, then asks Stable Diffusion how plausible an image of "X, side view&q

6D.ai wasn’t released until 2018. You may be thinking of Abound, which you wanted to license in March 2017. I don’t know of anyone else that had real-time meshing in 2017.

Interesting - I’ve never observed it kicking in. Would love to know in which circumstances it’s used. I assume you work for Apple to know this so understand if you can’t share more.

Correlation != causation. Try out our app, Metascan, to see an example of using TSDF with a multi-resolution GPU hashtable that only stores voxel data near surfaces. Or just skim the original voxel hashing paper from 2013 to understand the

ORB-SLAM2 is SLAM only (similar to ARKit w/o VIO) so only reconstructs feature points - no surfaces. This research is about surface reconstruction.

ARKit doesn’t use LiDAR for camera pose tracking. TSDF memory isn’t an issue since Niessner et al. (2013).

Their research doesn't just integrate depth maps into a TSDF - it uses NN's to incorporate surface priors. I don't recall you having similar real-time meshing functionality in 2016-2017, Andrew. Can you show what you had? As

I said "wanted it" not "wanted to build/finance it." Doubt he's given up wanting it. A human can always do better: take Google's results, then remove SEO spam/duplicates, extract more relevant snippet
