.B #include <allegro.h>

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