Work continues on creating 3D versions of our characters. Talented 3D artist Trentity DeWitt out did himself in creating the 3D Ribeye and Cubesteak, based on detailed model sheets drawn by Mike Milo.
Incidentally, 3D characters are usually constructed with their arms extended on a T-form as in these screenshots, because that's the most efficient way to model and 'rig' the character.
These models were built and rigged by Trentity using the 3D program called Maya, which is an industry standard 3D application. Many of the 3D special effects, and full 3D animation you may happen to see in movies and TV is done using Maya.
