I am still fascinated by our whacky "Speed of light" Gaussian Splatting renderer. It depth culls away nearly 90% of the scene and renders in 4ms. It's wild! and also completely unusable.

I might be having a little too much fun working on our @Apple Vision Pro support... Church on a stick! Scene by @Schindelar3D at superspl.at/scene/c67edb74

Ever wondered what #GaussianSplatting speed-of-light rendering might look like? This comes close: 7.5 ms a frame on a Pixel 7 Pro in Chrome/WebGPU, where sorting takes 19.5. The flickery blobs are a per-frame thing; over time they resolve to the correct image. Too flickery to ship as-is, but a useful stepping-stone. (I already have a version that resolves much better per frame — not quite as fast, of course.)

Even reasonably straightforward content like this HQ strawberry from @DanyBittel - superspl.at/scene/84df8849. You wouldn't expect performance issues with this scene, but actually when you zoom in, there is a TON of overdraw and the GPU starts struggling. Sorted: 14.3ms Stochastic 2.7ms (🤯)

It turns out that stochastic rendering of #GaussianSplatting scenes isn't just like, crazy super-duper fast, it also gives us new avenues for doing cool stuff. For example, how about dynamic point lights with shadows directly on the gaussian splat scene?! Scene by @DuckbillStudio superspl.at/scene/23ebe85c

I've added overdraw display to #SuperSplat editor. Runtime performance is heavily dependent on overdraw, so it's definitely a good idea to be aware of it in your scenes! And when comparing various trainers, overdraw is another quality metric to consider apart from PSNR! Right @lichtfeldstudio?
