 May 7 answered Problem with finding the intersection point between a line and triangle May 7 comment Problem with finding the intersection point between a line and triangle DAMN! Yeah, I see it now. I have thought of $d$ as an absolute position when it really is a vector. May 7 comment Problem with finding the intersection point between a line and triangle Sorry, I'm obviously confused. You're right again. Come to think of it, it doesn't seem possible to satisfy the equation $(1,1,1)+x(1,1,2) = (1,1,3)$. WTF? :/ I'm obviously seriously confused here. May 7 comment Problem with finding the intersection point between a line and triangle Yes, $b=(1,1,-2)$. That was a typo. Thanks! And yes, $(1,1,1)+2(1,1,2) = (3,3,5)$ but where do you get $2$ from?

But how is this a problem you mean?
