I was wondering if anyone knows of an algorithm that will find the intersection of a line and a triangle.
David
Why with a triangle and not more generaly between 2 lines ?
Or between a line and a surface ?
Can you make a schema ?

Distance:
From a line to … which part of triangle ?
Center of Triangle ? Most close vertex ?
Intersection:
What do you known (angle, vertex coordinate…)about triangle ?

Hi Zero
You will find that you want in this very well done imaging Site 
See Chapter about Line, and chapter about Plan& parametric equation 
It’s of course geometry in space!
Pilou
But maybe you want just find this intersection with a 3D program ?
Fantastic link. Thanks!
