Checking the vertices on GPU isn't don't something that is easy at runtime without changing the rendering quite extensively such as using Transfom_Feedback: https://www.khronos.org/opengl/wiki/Transform_Feedback The other possibility would be to see what tools are available on your OS/hardware/driver combination.
