I'm creating 3D animations using Mathematica. Suppose my scene has two spheres moving towards each other. Right now, for every frame, I redraw the whole scene. The approach is extraordinarily time-consuming. Is it possible to, instead, modify an existing Graphics3D object by changing the centers of the spheres.
Similar questions have been asked before, but not from the point of view of time-efficiency. I'm looking to avoid the time it takes to re-render complex 3D objects. In short, can a Graphics3D be transformed after it's been drawn.
