Fragment shaders can only go so far. Can you do in webgpu something like this?

outputTexture2d[inputTexture2d[inputPosition]]++

In other words, if you have a large texture with (x,y) coordinates of points, can you draw another texture that shows a density cloud of these points? In webgl2 it becomes a phd level problem.

One needs to do multiple passes, not sure if that is to be considered a PhD level problem.
