I am trying to create a function to check for collision between a moving sphere and a polygon. I Know how to check for collision between a sphere and a plane on which the poly lies, and how to find the point on the plane that is closest to the center of the sphere. My question is how can I check if this point is inside the polygon. Any help?

GameTutorials has a tutorial on polygon-sphere collision. It uses OpenGL but I'm sure you could port it to whatever you're using.

Google for "Improved Collision Detection and Response", by Kasper Fauerby. If you can find that paper, it will probably be helpful to you.
