I have been working on a problem where i have a lot of polys. For some
cases, i would like to use a single texture on the entire geoset. I have
been able to do this with automatic texture coordinate generation. But i
have a remaining problem. I would like to be able to assign the absolute
coordinate *where* the texture begins.
For the purposes of illustrating this, imagine the following case. Say i
want to put the Mona Lisa on a rectangle, composed of 4 individual
triangles (all part of a single geoset). But i want to be able to move the
image in a known way, such that i can have either the image appear exactly
as you might see it in the Lourve, or such that the image begins in the
geometric center of the 4 triangles (or anywhere inbetween). All the while
being able to stretch it (so that you only see part of the image) or shrink
it (such that you might see many copies of the image).
I currently can do all this, but lack understanding of how to
deterministically "place" the starting point of the image at any arbitrary
point. Any help would be greatly pfAppreciated!
