I still don't get the point of Gaussian Splats. How are they better than triangles?

- patcon 1y agoIt's just a simpler primitive I assume. Blurs and colors and angles are simpler than 3D geometries, so it's probably more aligned with working/thinking with other very low-level primitives with minimal dimensions (like the math of neural networks). I dunno, I'm kinda vibing a response here -- maybe someone else can give you a more authoritative answer

- poslathian 1y agoThey are differentiable which allows for image based rendering via solving the inverse of the rendering function via gradient decent
- jayd16 1y agoIt's really not a splat vs triangle thing. You're basically comparing points cloud data to triangles. Likely triangles are used to render the image in a traditional pipeline.
- danwills 1y agoI'm not an expert and have not yet worked with splats, however I understood that unlike super-sharp-edged triangles they can represent complicatedly-transparent 'soft' phenomena like fur or clouds or similar that would ordinarily need to be rendered using possibly semi-transparent curves/sheathes (for fur/grass) or voxels for cloudy things like steam/mist. I gather splats can also represent and reproduce a limited amount of view-dependent specularity, as other commenters have said this is not dynamic and cannot easily deal with changing scene geometry or light sources.. still sounds like a fun research-project I make it do more in terms of illumination though!
