Computer: Graphics: File: Format: 3D: Triangle: RAW: How to create 
triangle RAW format? [Pov-Ray]

---

This describes how to create a file containing 3D data in the
the PovRay RAW triangle format

===

The format is:

1. zero or more lines containing 9 triangle coordinates
   (these 9 coordinates per triangle *must* all be located on 1 line)

    Ax Ay Az Bx By Bz Cx Cz

===

Given a triangle with vertices A, B and C
and its corresponding x, y, z coordinates.


             (Ax, Ay, Az)

                  A
                /   \
               /     \
              /       \
             /         \
            /           \
           B-------------C

      (Bx, By, Bz)    (Cx, Cy, Cz)

===

e.g. here an example of 1 triangle,
     which means 3 points,
     and each of this 3 points has an x, y, z coordinate.

     Thus for each triangle 3 . 3 = 9 points (has to be on 1 line)
