I need a function for my engine which could tell me if a line hits a poly in 3D space. I had some bad ideas like subdividing the poly into small particles, but my guess is that I should use analythic geometry calculations and I''m not that good in math... Any other idea,tip,doc,code,link...? Thanks!

GameTutorials has a real nice and simple line and poly collision detection tutorial

this might help you

Orthogonal project the polygon to 2D in the direction of the line. now you can simply do a point - poly test in 2D.
