Note that light source is always looking at the center point (0,0,0). glCallList(address) easily enough. The order of your translate/rotate is wrong. • A default limit to the nesting level of 64. Names that reference valid display lists are executed; others are ignored. I got the hardcoded translation vector by taking the vector [0 4 0 0] and rotating it. glGetError() returns 0, glIsList(objs . That is, if M is the current matrix and T is the matrix passed to glMultMatrix, then M is replaced with M T. Saved searches Use saved searches to filter your results more quicklyThe glVertex function commands are used within glBegin / glEnd pairs to specify point, line, and polygon vertices. The commands saved in the display list are executed in order, just as if they were called without using a display list. OpenGL® 2.
