Does anyone know a good place to learn how to implement shadows in openGL? Or does anyone know how to do this? I know it isn’t built into openGL by default but I can’t seem to find any good examples. I’ve created a cube sitting on top of a plane in which I’m going to test this. I’ve created the cube and plane using:
glBegin(GL_QUADS);
to create a flat plane as well as a six sided cube that sits on that plane.
Creating shadows is an advanced technique (well, there are at least 3 methods applicable in your case). Before even attempting to do so, you need a firm grasp of OpenGL and it’s concepts.
OpenGL is not a scene graph, it’s a drawing API, so the idea is to combine drawing operations in a way, that you’ll end up with what looks like correct shadows.

Each finds tons of Google results. Add OpenGL to the seach term and you’ll get numerous tutorials for each.
