Hi list,

I'm trying to drape a picture onto a trimesh with key
points on the picture tied to each vertex of the
trimesh and each triangle from the original picture
fixed to a certain triangle on the trimesh. 
Specifically, the application is to place a photograph
onto a topographic terrain model, so that the
photograph makes it look more like the topography
would from the air.  The triangles will be irregular
and the photo may be larger or smaller than the
trimesh area.

I don't see a way of doing this out of the box with
the Trimesh class, but I really hope I'm missing
something.  Is this possible?  Or is there tears and
bloodshed ahead?

TIA - Peter
