I’m trying to learn how to create shadows in an opengl scene.
I’ve heard about a lot of ways (stencil shadows, volume shadows, ambient occlusion etc.) and I’m a bit lost in all of this.
Can anybody tell me what techniques are worth learning, and proper for a modern engine (using OGL 2.1/3.0+).
If anybody could point me also to some resources on these techniques I’d be grateful.
