This example showcases geometry feedback
across compute shaders.
It implements simple 2D reaction-diffusion.
Everything happens on the gpu, in compute shaders.
Init -> Diffuse -> React loop from one pframe to another.
Here, we turn the GPU data
into something visual:
- the "chemical" attribute, an abstract property of the reaction, is read in input of this shader.
- it outputs a new geometry with a color instead.
The unchanged buffers are reused, not copied.
Afterwards, a simple pipeline draws this geometry: a circle per vertex.
