simple opengl engine

I’m a c++ programmer using Borland c++ builder 5, and I’m working on a game project. I don’t want to focus on graphics, however, I will need to display and move some 3d objects. Not knowing too much about how to program in Opengl and also trying to avoid spending too much time on graphics, I’ve been looking for a downloadable 3d engine that will allow me to quickly and easily display and move 3d objects (although RAW or OBJ import would be nice.) I don’t need physics, or anything like that. I’ve been having a very hard time finding something like this. Does anyone here know of such a basic engine? Preferably well documented enough to figure out. Thanks in advance.
