hi all...
we are having a problm in our graduate project... in some phase in the project we needed to do meshing and triangulation for a person in a 2D image, wihch did succefully, thx God (now we have the vertices and triangles connecting them)... the next step is to prform texture mapping to our generated mesh... but after we set texture positions rendering the textured mesh... the output of texture mapping on my laptop wasn't properly drawn... although it's working properly at our supervisor's pc!! can anybody plz hlp us find a reason for this...

I'm sending a link having the original img and the output of the texture mapping on my laptop...

we are using DirectX 9.0 in our texture mapping

It looks like the texture coordinate of one vertex of each triangle is possibly correct but then is being used for the whole triangle. Can't see why it would be okay on one machine and not on another though. I take it you've got the latest graphics drivers etc. ? are you using shaders or fixed function pipeline ?

If you're using pretransformed coordinates, make sure that your w coordinates are not zero.
