Drawing “point-like” shapes in OpenGL, indifferent to zoom

Question

I\'m working with Qt and QWt3D Plotting tools, and extending them to provide some 3-D and 2-D plotting functionality that I need, so I\'m learning some OpenGL in the process.

Answer 1

What you want is called a "point sprite." OpenGL1.4 supports these through the ARB_point_sprite extension.
