I want to ani-alias a scene, but the only things I am using now is the glEnable(GL_POINT_SMOOTH etc. all these functions. Now I read that OpenGL was planning to remove this way of anti-aliasing, and that some new driver will stop supporting this method. And because of some other reasons, I want to use multi-sampling as a way to perfomr this action. Could anyone explain this method to me? I read some tutorials, but I couldn't comprehend the whole story.
