I'm trying to implement knapsack using OpenGL. I'm generating balls of given weight and profit taking values from the user, and then draw balls on the screen. I want to send the balls which are selected into a box but I'm not at all able to move the ball. Can you suggest a way to move a ball from point A to point B forming a trajectory in 2d?

I think linear interpolation is what you need.
