Greetings To EveryOne that is going to read this. I have a problem with the shadow volumes. 1 . When i finallized the shadow volumes via the stencil buffer and with the help of the "Carmack''s reverse" , I notice that a quad follow the camera all the time , when i''m in the shadow volume. I read in the robust stencil shadow pdf of the nvidia about the "Caps of the Volume" so i draw them.Now if i draw the shadow volume is closed from up and down,but the regtangle follow me every time i go in the shadow volume. 2 . The other problem is that the shadow volume cut off all the polygons across his direction,with result that the second floor has a shadow from the first shadow volume. Is the problem that i''m using gluLookAt and not glTranslate. Why i never found a source code or a tutorial that somebody uses gluLookAt. All the tutorials that i found either the camera not moving into the shadow volume,eiter the camera not moving into the shadow volume and the movement (out of the shadow volume -- It has Limitations) was done by glTranslatef. Sorry for my BAD BAD BAD English but i hope that you get what is the problem. Please I''m desperate. Answer.!!!!!!!!!! Thanks in advance.
