what about considering a vertex as an object?

maybe if you draw your model with a dummy name on the name stack, then draw your vertex only with a relevant name on the name stack and a GL_POINT_SIZE big enough not to search the exact pixel

i have never done this and i have no example, but i think this should work. if you managed to do object picking this should be easy to test.
please tell me how it worked

have fun!

Just extract the frustum planes ( tutorial ) and find the verts that are inside these planes.
