triangle_interpolate, a Python code which demonstrates some simple techniques for interpolating data on a triangle.

In the most common case, the value of a quantity is known at the vertices of a triangle, and a reasonable interpolated value is desired at some point p in the interior of that triangle. This can be done by linear interpolation.
