A few weeks back I shared a link to the Foundations of Computer Graphics course being offered free at Berkley. Well, the Awesomeness that is Udacity are also offering an introductory course to 3D Computer Graphics, with a focus on Interactive Rendering.
About the course
CS291 will teach you about the basic principles of 3D computer graphics: meshes, transforms, cameras, materials, lighting, and animation. By the end of this class you will know enough to make an animated 3D demo program that runs in a web browser, while also understanding some basic principles of how realistic computer images are generated.
