Picking with core profile 3.3

Hi All

The typical recommendation is to use “unique color” for each primitive (vertex, face, object, I've all cases). Unfortunately such colors are not suitable for my needs:

  • there is a case when a vertex must be selected no matter how it's obsured 
  • often meshes are “too dense”. e.g. a pixel covers 2 or more primitives

Same time I've a case “select visible (not obsured) only". e.g. I can't just use “brute force” on CPU. 

Any advice?

Thx
