Webgpu: use a GPUBuffer directly for creating a VertexBuffer

EDIT:

Data transfer from compute shader to renderer

When I started learning about compute-shaders a few weeks ago, I looked at the Babylon examples in the docs and realized that I should first get a basic idea of WebGPU and WGSL to understand what is going on. Now I have a project where a compute-shader (set up outside of the Babylon classes) calculates new positions of a large particle system each frame and then I let Babylon render the particle meshes with an SPS. The bottleneck is the GPU → CPU data shoveling (mapping a buffer), which I knew…

Move data between ComputeShader buffer and ShaderMaterial

Hi, I am pretty new to Babylon.JS, love it so far, but got stumped with shaders recently. I have been trying to implement a heatmap over a 3d mesh and ran into a wall. I have a bunch of points (P) just outside of the surface of the mesh in a non-uniform distribution and it would be pretty cool to show the distribution as a heatmap on the mesh’s surface. I decided to use WGSL ComputeShaders for heat calculation, as plain old javascript calcs for vertex colors were incredibly slow. My thinking is…
