• Mon Jan 22, 2006: Homework 1 ( part a, part b ), Transformations, Due Mon Feb 5
  The winding order on the glut teapot is incorrect (I think its a glut bug). If you have backface culling on (you should) you won't see the teapot, it wll be drawn black (back faces of triangles). To fix this do the following in your display routine for the teapot.
  
  glMatrixMode(GL_MODELVIEW);
  glPushMatrix();
       glLoadIdentity();
       glRotatef(180, 0,0,1); // NEEDED TO CORRECT WINDING ORDER
       glScalef(-1,-1,-1); // NEEDED TO CORRECT WINDING ORDER
       glutSolidTeapot(0.2);
  glPopMatrix();
  
  You could also just turn off backface culling, but you normally don't want to pay the performance penalty.
