me again :)
simple question, hopefully with a simple answer: What is the third part of the texture-coordinates for? Im speaking of the data obtained from the UVWtag...

same as XYZ, programmers decided to call texture coords UVW to avoid confusion when reffering to coords.
on a model XYZ or a texture UVW.

The W is a third component that is used pin 3D shaders, as it is done with the stick texture tag for instance.
cheers,

well okay... I never used 3D shaders (not a good idea in game/realtime grphics anyway, I think^^), so I will just go on ignoring them :)
thanks

As Matthias notes, the W is not just a convenience but a real part of the UVW 'space'. Most of the time we deal only with the UV 'plane', but it is possible for texturing to have a third component and is used most especially with volumetric shaders.
