[gameprogrammer] Texture Coordinates

Hi Guys,

I am looking for some advice on how best to determine texture
coordinates for vertices.  I have been developing a 3D model utility
that can be used to create models for use in games and I am looking
for the best way of setting up texture coordinates.  The model format
is a simple array of vertices that are arranged into stacks of
TRIANGLE_STRIPS.  Each vertex has an assigned set of Texture
Coordinates.  I can create a new mesh, say a 4 vertex quad with
texture coordinates assigned correctly.  I can then subdivide the mesh
into 9 vertices and again into 25 vertices.  I don't have a problem
preserving the texture coordinates during subdivision but when I start
maniplulating the vertex coordinates it will stretch and skew the
texture.  I have no issues with why this is occuring, I am just
looking for advice on how best to manage texture coordinates.

At the moment, the application allows you to select vertices and
adjust the texture coordinates manually but I am sure there must be a
better way of doing it that that...

Any thoughts?

Richard


P.S. If anyone is interesting in assisting with some testing of this
app then let me know.  I am thinking of making it freely available
when completed if there is some interest.
