Hi!
I'm working on a simple 3D engine in OpenGL. And wrapping most of it. My goal is that the API isn't "visible", so I can make a DX version later 
Well, my problem right now is how I manipulate ONE object.
I have a class called cPrimitive, it's basicly a Mesh, storing vertices and vertexindexes. It can represent cubes, triangles, pyramids, and such. But I want to be able to transform the cPrimitive. Meaning Translating, Rotating or Scaling it based on it's own vertices and not the world.
I know that I can:
But that must be done every time I render. I want to _permanently_ change the primitive.
Is there some OGL or GLUT support for that? Or do I have to code my own Matrix classes and bring up my old algebra book?

glPushMatrix(); glTransformf(...); // or whatever glPopMatrix();
