They can be any of the affine transformations. That includes translation, scaling, rotation, shear, and reflection transformations. We (traditionally) have these coordinate systems to work with:

Although OpenGL allows you to decide on these steps yourself, all 3D graphics applications use a variation of the process described here. Each transformation transforms a vector into a new coordinate system, thus moving to the next step. shapefrom-silhouetteWebLearn OpenGL is free, and will always be free, for anyone who wants to start with graphics programming.
