Both ran fine here Peter. I enjoyed the space ghosts!

Can I hit them with a Badminton racket? :)

If you want to maintain the correct x y proportions when the screen is resized then monitor the client rectangle set the perspective at the beginning of each frame:

Code: OxygenBasic

1.   'SET THE VIEWPORT AND PERSPECTIVE
2.  '
3.  GetClientRect  hwnd,&cRect
4.   glViewport 0, 0, crect.right, crect.bottom
5.   double aspect=crect.right/crect.bottom
6.   '
7.  glMatrixMode   GL_PROJECTION
8.   glLoadIdentity
9.   gluPerspective 45, aspect, 1.0, 100
10.   glMatrixMode   GL_MODELVIEW
11.   glLoadIdentity
12.   '
13.  glClear GL_COLOR_BUFFER_BIT or GL_DEPTH_BUFFER_BIT
14.   glClearColor 0.5, 0, 0, 0
15.   ...
16.

I'll give it a try Peter. Do you also know a substitute for gluLookAt ? I would prefer to use only GL functions if possible.

Thanks
