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.
