Hi guys

Sorry for a stupid question, first of all. I would like to visualize a "corner-point grids" (http://en.wikipedia.org/wiki/Corner-point_grid) model using OpenGL only, but looks like it's not so obvious as I thought before .
Typical model looks like this :



So, am I right in thinking, that OpenGL doesn't provide "hidden surface removal" solutions and I have to implement all that stuff on CPU (I mean all that terible words : BSP trees, z-buffers, painter's algoritms etc) instead of using my GPU?

Or may be someone can give me advice how to visualize such models, that would be really cool

Thanks,
Maxim
