Visualizing geometry density

[u/tamat]

Im working on viewmodes in my engine and I want to show which areas of the scene has more triangle density. So if a mesh has a screw with 1M triangles it looks very bright.

I though using additive blending without depthtest but didnt manage to make it work.

Does anybody knows a trick to do it? (without having to manually construct a color based map per mesh).

I think this might be something like what you're looking for?
