If you can, you should try and create surfaces that are a power of 2 - that is, sizes like 16,32,64,128, 256 and so on - as some older hardware can't do this. The need for this is becoming a rarity, but worth remembering.
WebSep 22, 2011 · N : the surface normal for the Plane. And i have a very large, flat square Polygon, which I want to render to represent this Plane. I can easily translate the polygon to the given point, but then I need to find the proper rotation to apply to make the surface normal actually be the surface normal. I tried a method mentioned else where which was:
