DUH!! It's not a variable! rti() is the complete function ready - made. You don't have to edit it! :P
rti() returns if the point is inside the triangle. I've already made it! see below for an example.

Example of use.
suppose we have, a triangle with points (1,2,3), (2,3,4), (3,4,5).
and a ray line from points (3,2,1), (2,0,1).

Rename rti.cpp to rti.h (should have done this myself - sorry)

And in your main program:
#include "rti.h"
...
float xi, yi, zi;
...
inTri = rti(1,2,3,2,3,4,3,4,5,3,2,1,2,0,1,&xi,&yi,&zi);
if (inTri == true)
{
    // The point is in the triangle.
    // The point is (xi,yi,zi) - do something with it!
}
else
{
    // The point is not in the triangle.
}

cooldude234:
whoops I read it totally wrong. But it didn't really matter I added the code into my own function anyway
But it still didn't work

Raxx:
Doesn't Thanos's function work standalone? If it does then it's a problem with the input, and you need to recheck how you are using it.

Thanos:
I might make a small example application as well, just to make sure it works standalone.

You know, I shouldn't be sure about anything:
Programmer's rule #1: "Thou shalt not expect thy code bug free."

EDIT: Uhh  :-[  :-X it seems it needs just a tad of debugging, I'm sorry cooldude234!!

Yea, it would really help if I understood the math to this whole thing. I can't tell if it's something wrong with my code, the code I based my code off of, or thanos's code or if the universe just like messing with me :S
