Thanx Ranga for your detailed reply using your ksfo airport I use lp tokens and turn on runway lights now i got shemes on position our russian runway lights and try to place runway lights according scheme "Ray" or "Lutch" in russian transcription as i understand rway_dir variable shows us landing direction on runway it's normalize vector rway_normal it's normal to runway or what? normal to point light? or raycasting direction in tileentry.cxx there is a code //EDGE setColor(0.0,0.0,-1.0,180.0, 1, 1, 0.5, 1); why 180 and not 360? and on vasi //VASI lights setColor(0.0,0.0,1.0,360.0, 0, 0, 0, 0); setColor2(10.0, 40.0, 1, 1, 1, 1); setColor2(6.0, 40.0, 1, 0.5, 0.5, 1); setColor2(5.0, 40.0, 1, 0, 0, 1); why here 360 and 10, 40, 6, 5 I understand Ranga that maybe you not use this code but maybe someone (Christian?) explain me this magic numbers Also I complied flightgear to see lights usung MSVC but when I use cygwin I got nothing cygwin's glut does not support opengl extensions :(((( As I understand now you are working on Mandrake and use Nvidia linux drivers that support extensions when i compiled on linux should I simply rename wgl to xgl and all works fine? Your comments? Thanx Bye
