NAME

       exshade - Gouraud shaded sprites. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example exshade

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.
