The dots are usually of a single color.
So you need four positions and two triangles, like 0 1 2 0 1 3.
For each vertex specified, it draws a point. for the ball to reach the destination, you need to have the proper level of ingenuity and quick reaction, without which you will have a hard time. Then of course you must make sure that the orientation of this rectangle is so that it is facing the camera. Here are a number of highest rated python 3d drawing pictures upon internet.
