Hi, I am currently loading a Q3 .map file. While loading the geometry data works fine now, I have problems calculating the texture coordinates for a brush. A Brush line in the file looks like this: ( 64 0 0 ) ( 0 0 0 ) ( 0 0 64 ) BCRATE02 1 0 0 0 0 0 -1 0 The last eight values define the texture space. What I do at the moment is the following: 1. Load each four values into a plane 2. Calculate s, t seperately: s = ( vertex * plane1.normal + plane1.d ) / Texture_Width; Unfortunaltely the values become very big. Is this method correct and if yes how can I transform the coordinates into the range [ 0, 1 ]? Any help is greatly appreciated. -Dirk PS: Does anybody know how to parse the patch definitions?
