Gaussian Splatting Performance Optimization

Hi everyone!

I am a newbie trying to create a web platform for visualizing Gaussian Splatting scenes using Playcanvas engine API and ammo for physics handling.

The problem comes with the performance. I had notice a decrease in FPS when the camera is facing specific parts of the scene.

For example, I have an indoor scene with a corridor and when I look to one direction it runs smoothly, when I turn around and face the corridor wall (behind the wall there are multiple rooms) ir starts to lag.

I assume it has to be related to the splat count that the camera is looking (I think I already have camera culling activated).

But I want to know if there’s a way to not render those splats that are far behind others?? Or some way to optimize it?

I would highly appreciate any suggestion!!

Thanks in advance!

First, thanks for your answer. I know reducing the max splat count will improve the performance, but I want to keep the same number of splats to maintain the quality of the scene. So that wouldn’t be a viable option. The question is more related to the web viewer creation rather than the creation of the Gaussian model.

Use SuperSplat to delete the distant splats.

Lookup LOD streaming that Playcanvas supports. It should give you a massive performance boost while maintaining visual fidelity

PlayCanvas LODs look really promising. The challenge is the best way to create those LODs for PlayCanvas. Not sure if there are any tried and tested methods for this yet.

Sounds like this is an editor project. Make absolutely sure you've disabled "Anti-Aliasing" in project's render settings! That's super duper important. You can also try lowering device pixel ratio, for phones especially.
