Question
Can you give me an example of how in OpenGL for C++, and how I can implement physics, of how a sphere is going to be on a plane, and would this work adding gravity and uniform circular motion to the 3D Sphere? (Considering adding gravity and acceleration.)
Basically I would like to know how would you apply physics gravity and uniform circular motion on this 3D sphere, in the context of
