If I try to do this:

DrawFunc( pfChannel *chan, void *data )
{
   
  pfDraw( ) // draw the entire scene
   
  for( int j = 0; j < DLlist->getNum( ); j++ )
  {
    pfDispList *dl = ( (pfDispList*) DLlist->get( j ) );

    if( dl )
      dl->draw( );
  }

}

After the pfDraw(), it will not render the geometry in the display
lists. However, if I comment out the pfDraw(), it will render the display
lists.

If I put the pfDraw() after drawing the display lists, it renders as
expected. But I need to initialize the z-buffer before I render my
display lists.

What am I doing wrong? Why is pfDraw() preventing my display lists from
rendering?
