Natural-Selection simply does a traceline from the top of the map to the bottom for each pixel. If nothing was hit then the pixel is black (or transparent). Otherwise the z-coordinate of the impact point is used to choose a shade of blue (darker == lower I think). I believe a second pass is made over the image: pixels that aren't black but are next to a black pixel are walls and are coloured white. -- Philip Searle ----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
