Really amazing video. Unfortunately this article is like 60% over my head. Regardless, I actually love reading jargon-filled statements like this that are totally normal to the initiated but are completely inscrutable to outsiders.

    "That data was then brought into Houdini, where the post production team used CG Nomads GSOPs for manipulation and sequencing, and OTOY’s OctaneRender for final rendering. Thanks to this combination, the production team was also able to relight the splats."

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 manipulating vast numbers of points, and renderers (such as Octane) can now leverage this type of data to integrate with traditional computer graphics primitives, lights, and techniques.

My bad! I am the author. Gaussian splatting allows you to take a series of normal 2D images or a video and reconstruct very lifelike 3D from it. It’s a type of radiance field, like NeRFs or voxel based methods like Plenoxels!

Corridor has done some great stuff with Gaussian Splats, I recommend this video for a primer!

Reminds me of Kurtwood Smith’s piping sales pitch in The Patriot
