The first 5 lessons (out of 9 total) of 3D Graphics are now available! You will finally find the answers to common questions like, “which way is up (Y or Z)” and you will learn how to create, combine and transform objects and even deal with transparency and advanced matrix operations. You will start by learning how to draw a single triangle on screen and by lesson 5, you will be able to make some pretty impressive interactive demos.
This is a summary the online course provided by udacity on interactive 3D rendering.
