Tutorial or examples of 3d graphics in c++?

Are there any tutorials or examples of 3d graphics in c++, besides the samples included in the installation of pspdev? Thanx...

For the PSP or in general?

In general, you be looking at http://nehe.gamedev.net/

The PSP is pretty similar to opengl but I think there are some at http://psp-programming.com

For the PSP...

Thanks, there's a tutorial on the psp-programming site that seems pretty complete. I hope it won't be too difficult to put it into practice.
