We could get better compression using a custom encoder, however with webp the browser decodes off the main thread, copies the resulting data to GPU memory and caches the images for us. All very useful on the web!

Perhaps niche compared to the entire web, but we use lossless webp for gaussian splat data delivery for realtime rendering. ( https://developer.playcanvas.com/user-manual/gaussian-splatt... ). Scenes often comprise gigab

The two challenges with something like this are: 1. Capturing the entire scene with photos or video and converting ("training") these into a 3d Gaussian splat. This is what Vincent did so well with Grace. Open source tools for tra

Hello, I'm wondering whatever you mean? You can absolutely walk around the church indoors on mobile. Just tap to walk.

If you can, please check any output/errors on the developer console?

We (playcanvas) use k-means clustering to generate a 64k entry palette of coefficients in our SOG compressed GS format. The data savings are huge, but the compression step is slow and requires a GPU. It would be awesome if we could find a b

Right, thanks for confirming. It seems firefox related. We'll get this patched asap!

Hello, playcanvas developer here. May I ask what phone/device you're on? Might be a bug. (No pun intended).

Have you tested the shader's runtime performance penalty after minification? Also wondering how you handle named uniforms?

Some of these would be better converted to 3dgs.

This app was made in the PlayCanvas editor. The models were imported and a custom GLSL shader written to handle the particle animations.

I'm not really sure what you mean. Think of SuperSplat as the photoshop of gaussian splats? - SuperSplat dev :)

I love this article! I used it as a basis for the multi-level grid in SuperSplat ( https://playcanvas.com/supersplat/editor ).

Yes Dreams is actually a huge inspiration with the realtime rendering side of gaussian splatting. Specifically this presentation by Alex Evans https://www.mediamolecule.com/blog/article/siggraph_2015 . Dreams doesn

Did you see that we credit Aras at the end of the post and link to his website?

Splats change color based on direction, but opacity is constant.

by slimbuck 3y ago
Yes! We are using this clustering approach for position and scale data.

It's definitely possible to compress/palletise the SH bands (see https://aras-p.info/blog/2023/09/27/Making-Gaussian-Splats-m... for one approach). We just found that splats encode some view-de
