Two part. Looking for a 3D artist, and assistance with 3D collisions.

[chamberlain]

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.

For object-to-object collisions, I just do OBBs(via SAT) or sphere to sphere collisions.

For terrain to player/entity I do an octree + triangles inside a node vs player sphere collision.  Just get a point from the sphere and do a point in triangle test and classify what side of the plane the sphere is on and do your collision response.

Or just use Newton. ;*)
