A simple rendering library?

Question

infographics

A simple aircraft simulator needs a library to render the vehicle, surface, and sky.
With the ability to build a device model from primitives or load a model from a file, simple camera control, adding a drop shadow to the surface.
Now everything is written in OpenGL, but doing all of the above is difficult on it.
Maybe there is some library based on OpenGL for such purposes?
