Is it possible to have a drawable that isn't drawn? I have a complex object split into a number of geodes but sharing a common vertex array - this is necessary because some of the meshes combine across objects.
But I do need a way of quickly knowing if a particular vertex is in a certain geometry from the primitiveIndex returned by a pick. If they were just points this is easy - because the vertices are in order (ie, first N are in first geometry, next M are the 2nd etc) But there is no easy way to count how many points are in a line or triangle geometry. I thought of having a drawarray of points for each part but somehow setting it to not actually draw them as points - is there any way to achieve this? The alternative is to have a vertexattribute but this seemed a bit over kill if I only read need to store a few indices.
