I'm attempting to setup a display list, and then call it in my
drawRect function whenever my alarm fires. Now, drawRect is being
called per alarm fire as it should, and my glCallList function is
inside of drawRect, but for some reason the display list is only being
called twice, even though drawRect is being called every 0.004
Code for initGL:
theSun = glGenLists(1);
glNewList( theSun, GL_COMPILE );
sun->Draw( light_position );
Code for drawRect:
glCallList( theSun );
I believe you need to flush the command stream. At the end of
-drawRect, call -flushBuffer on the context, or just glFlush().
gl seems to be aggregating the calls to glCallList and basically
throwing away what it thinks are duplicates, maybe? I don't know for
sure so you may want to check with the macopengl list.
