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 goraud shaded sprite will show the direction of the light.
