The rasterization shader has many opportunities for improvement.

The largest performance hit right now is the loop which handles the color contribution from every splat in the tile.

Some great optimizations would involve effectively culling and early stopping of the loop, less global memory fetches and less branching.

Today the sorting array size is set to 14mil entries to accommodate for larger scenes, this makes the performance suffer for smaller scenes more than necessary, but the amount of total splat-tile intersections is variable every viewpoint, which means we can't use a static array size based on the scene.

Hello,

Thanks for your code.
First, we have started the project on my server.
Next, we have used the --host option to expose the network.
Then, we visit the website, and we can see the interface of the website.

After, we upload the ply file. The website can not show the 3D model. Moreover, it shows a message:
"Error: WebGPU not supported on this browser! (navigator.gpu is null)"

How can we solve this problem?

Hello, i tried using the Demo (https://splatting.marcussvensson.com/) with the example data any custom data on a rtx 3070 but the results were always completely black or consited of black horizontal lines. Is there a solutions to this? Great Project!

The last subpass in one sort pass just before the scatter accesses the shared memory in a strided way which means there could be a potential performance gain in the memory access pattern.
