2d lighting needed

Anyone know of good libraries/apis/algorithms for (dynamic) lighting/shadows using C++?


All I'm basically looking for is something that will work for a top down game with lights and objects in one plane although a more elaborate solution with extras is also welcome. Something like this would be nice

In order to achieve that sort of effect, you'll need 3D geometry and lights in 3D space, but you can keep it simple: maybe the floor is at z=0 and the walls rise up to z=1, or something equally straightforward.

In order to get a 2D appearance, simply use glOrtho() to set up your projection matrix.

OpenGL does not directly support shadows, but there are some techniques for generating them:
