Proposal: 3D Computer Graphics
There is a site named Computer Graphics, which currently is in public beta and is for computer graphics researchers and programmers. While the scopes of both sites are different and I'm happy to see a site about modeling and animation, I don't think it is a good idea to have two sites with nearly identical names.
Having two sites, Computer Graphics and 3D Computer Graphics will cause a lot of confusion, especially for new users. Almost certainly, they will think that one site is for 2D and the other for 3D, but otherwise identical scope. And this is not true.
I recommend to rename this new proposed site, so that users have a chance of guessing the scopes correctly. Maybe it could be named 3D Modeling and Animation, which fits the headline of the proposal better and can be distinguished from Computer Graphics.
