Creating 3D mesh from points

I need to generate a 3D mesh from a series of points and do not know where to begin. If I should post this in a different forum, please let me know.

The image contains up to 2880 XY points for each z position, and up to 50 different z positions. The image is not static, the XY points for each z position will be constantly updated.

I would be greatly appreciate any ideas or suggestions.

OpenGL is about drawing geometry. Your problem is about
creating geometry.

This is a computational geometry problem. See Delaunay triangulation.
