On a classis laptop, it behaves well
- PaulHoule 2y agoThe quest is underpowered (it's basically a midrange Android phone you wear.) More efficient coding or a simpler model would help. Inside the Scaniverse does something similar with a high framerate but the models are simple and don't look very good. I had to power cycle mine to get out, but boy was the view great despite the motion sickness.
- ladon86 2y agoThe Quest's Snapdragon GPU, like most mobile GPUs, uses a tiled rendering [1] architecture. The basic technique for rendering gaussian splats is kryptonite for this architecture, essentially implementing every worse practice for rendering on a mobile GPU: * Tons of overdraw (overlapping splats) * Tons of alpha blending * Millions of splats in the distance generate a lot of tiny triangles resolving to a single pixel * Long thin splats in the foreground generate triangles that cover multiple tiles These are all the ingredients you need to bring a mobile GPU to its knees! Any desktop GPU (including most laptops) will be far less sensitive to these issues, even if it's not very powerful. It's a fundamental issue of architecture rather than one of raw FLOPs.

- OrangeMusic 2y agoIt _is_ possible to render incredible and gorgeous scenes using gaussian splats on the Quest platform though, as shown by this tech demo from Meta: https://www.youtube.com/clip/UgkxGlXM3v93kLg1D9qjJIKmvIYW-vHvdbd0 https://www.youtube.com/clip/UgkxGlXM3v93kLg1D9qjJIKmvIYW-vH...
