I like 800x480 or 1024x600
Why? Because they are widescreen, suggested by my GPU / OpenGL thingie and fit within my 1366x768 screen.

I'm looking for 2 things. I'm new here and forgive me if I've incorrectly placed this topic.

I'm looking for someone who would basically create 3D art for me for "free", as in no payment but still gets a big name on the opening credits. ( unless of course I somehow do make money off a project, then I'll share the glory! )
I would draw the concept most of the things I want and this artist person could make them for me... though I'm not against working side by side with an artist to be more involved... a collab? Is that the word?

Secondly, and more important. 3D Collisions.
I haven't searched these forums yet ( and I promptly will ) but I would like to know where to begin with implementing 3D Collisions. I'm using LWJGL and written my own "engine" out of that. I would like to have collision objects that can detect each other, and detect collisions with multiple environment tri-meshes.

To be specific..

I loosely already understand:
Sphere-Sphere, AABB-AABB

I'll need additional help with:
Sphere-Triangle and AABB-Triangle

I may also ( depending ) may need cylinder / can / capsule... that seems to be a trend for character controllers.

Edit: Forgot to mention I'd rather avoid using an external / 3rd party library, unless it dealt with collisions only. I don't want to to use ode4j, jbullet or the sort.
