[Algorithms] Highest Quality Look for 3-d Characters

[Matt H. <ha...@ui...>]

When using a real-time engine that supports, for example, OpenGL and
DirectD3D, what is the best advice I can give to 3-d artists to make it look
as best as possible?

I'm rendering out a 3-d character, and he looks pretty good.  I'm wondernig
how much can be done with Texture Maps, Polygon COunts/Bezier Curves,
Lights, Effects (Shadows, specular, etc.) to make him look even better or
more realistic.

What technologies are used to maximize the overall look of rendered
characters or environments?  What tricks are required in texture maps to
make them look best?  What is the ideal light setup?  What can I do with
software to increase visual quality?

I hope my question is coming out clearly.  I'm trying to decide if a 3-d
character can look better, and I think it can, but how?

HAPPY NEW YEAR!
