Hi Folks....

I have a way cool new module that I've put up at the IAC.  It's so
way cool that I thought I should say something to the net.

A few days ago, someone posted asking for a module that would produce
a mesh from a 2d rectilinear field.  This note is a follow-up to a 
previous post on that subject.

The new module, called "texture mesh", takes 2D data of any type and
creates a quad mesh.  If you have ever tried to make a height map of
a 2d rectilinear field using "field to mesh", you will like this module.

I'll try to be brief about what this module does:
	1. take a 2D field, create a quad mesh.  for uniform fields,
		the x,y coords come from the extent info, if present,
		or the size if not.  the z values come from the data.
		for 2D rectilinear fields, the x,y coords are specified
		in the field, the z- values come from the data.
		for 2D 3-space irregular fields, all of x,y,z are
		present in the field.  2D 2-space irregular fields are
		treated exactly like rectilinear fields.
	2. do something "intelligent" about texture mapping (I'll save
		you wise guys the effort of stating that intelligence
		is in the eyes of the beholder).  One can set the
		UV coordinates in the field, and subsequently use 
		dynamic texture mapping in the software renderer, or
		one can color the vertices of the mesh using an image.
		In either case, one can move the texture around and do
		texture scaling (no rotations or non-affine transforms)
		using the parameters provided for controlling the UV
		mapping of texture to mesh.

I have found a million and one uses for this module.  Don't know why I
didn't write it sooner.  Plus, if it breaks, or you don't like something
about it, you can do something about it (scream at me, or fix it yourself).

Now, isn't that SPECIAL!  ;-) ;-)

ps- give the IAC a couple of days to unpack it, install, port and test it
on all AVS platforms.
