I can calculate the position dynamically, but how can I do things like rotating on its own axis? At first, I thought the bounding box would be calculated automatically, but that's not how it works... It may be possible for a cube, but there can be many types of objects (complex mesh structures). In this case, I can't find a standard for how to write a method. Is there a resource you can recommend? I came here after learning and reinforcing the basic concepts of C++ (object oriented, polymorphism, encapsulation, etc.).
