texture transformation

[zyllabaua]

Hello!

have u ever read this page?

http://msdn.microsoft.com/library/e...ction/textures/coordinates/specialeffects.asp

microsoft describes how to transform texture coordinates.
my problem is, that i'm not able to translate my coordinates, because it seems that the input rhw is zero when applying the transformation matrix.

doesn't anybody know how i could solve this problem?

thanks

It would help if I could view a little source snippet to see what your doing in your code.

i have just found out what was wrong
texture coordinates are 2 dimensional
so the w coordinate is not 1, but the z coordinate is
i have simply put the tranlation values to the wrong row of the transformation matrix
