I was wondering if the q-texturecoordinate does something other than just dividing the s,t and r coordinates???
That’s all it does. However, that is significant, and is useful in certain situations (e.g. fitting a texture map to a trapezoid without requiring any vertex to have more than one texture co-ordinate, i.e. texture projection).

could you be a little more expilcit, how asign the texturecoordinates to a trapezoid by using the q-coord.
hmmm i think i am just an idiot… 
thx that helped…
