Line-triangle collisions?

You might have better luck googling 'ray triangle intersection' or 'triangle raytracing'. With the right search terms you should have no trouble finding references; ray-triangle intersection is well documented online.

Not all ray-triangle intersection algorithms are equally robust, but whether these issues are a factor can depend on in what context you're using the test.

I posted this one several times, so tell me if i'm getting irritant:
Line- Triangle Collision Code

Thanks for that link Kwak; It seems like it'll work great, but I have a question about it. What would VECTOR3::subs() be?

Some time ago I needed an algorithm like that too, and I found a very nice and fast triangle collision algorithm in the Irrlicht source code. Take a look at triangle3d.h in the Irrlicht /include

Simple vector subtraction (always thought it was named subStraction so i named it subs, should be sub then)

subs(v1, v2) = v1-v2

EDIT: I have changed the post in the link and added the sub code ;)

Thanks Kwak, that was really helpful, and with a few modifications, it worked perfectly. Rate++ :D

Glad to hear it helped.
