For example Quake3 bsp stores them in such way: <snip> floor() and ceil() return the floor and ceiling value of an argument. floor rounds a value down to the nearest integer, ceil rounds it up to the nearest integer. If I remember correctly, Quake3 lightmaps were much different (and simpler) than Quake I/II lightmaps. The lightmap code I copied from Alexey Goloshubin's Poly Engine source code... http://www.ii.uib.no/~alexey/ I never found any detailed explanation of the Quake I/II lightmaps anywhere on the Internet. The Quake I source code (ftp.idsoftware.com) and Alexey's functions were pretty much all I used to handle lightmaps for my BSP viewer.
