The second does a triangulation. Though I didn't understand what to do with the

Once you've got the triangulation, you can linearly interpolate between the three points of the triangle that a point is in for which you want the value.
I see. Thanks for explaining.
I've been meaning to wrap Jonathan Shewchuk's triangle code for Python, but haven't gotten around to it yet.
Does that code include the interpolation, i.e. the extraction of data on a regular grid? I can't imagine an easy way to achieve that.
