DESCRIPTION

15       This program demonstrates how to draw Gouraud shaded (lit) sprites.  In
16       an apparently black screen, a planet like sprite is drawn close to  the
17       middle of the screen. In a similar way to how the first test of extrans
18       works, you move the cursor on the screen with the  mouse.  Attached  to
19       this  mouse  you can imagine a virtual spotlight illuminating the scene
20       around. Depending on where the mouse is, the Gouraud shaded sprite will
21       show the direction of the light.
