Data transfer from compute shader to renderer

[Evgeni_Popov]

My question is: If I would use the compute-shader class within Babylon, can I avoid this bottleneck and render the SPS with data directly from the GPU buffer?

It should work.

I think this post should help you regarding the setup of a vertex buffer that can be updated by a compute shader:

Compute Shaders Order Execution

Yes, you do a read to CPU by doing that, and it is delayed by one frame because it is using a promise (the promise is resolved after we finished processing the frame on Babylon side). You should create a storage buffer with the VERTEX flag, so that you can use it as a vertex buffer. See how it is done in the Boids compute shader example: Creation of the buffers: this.particleBuffers = [ new BABYLON.StorageBuffer(engine, initialParticleData.byteLength, BABYLON.Constants.BUFFER_CREATIONF…
