# exshade(3alleg)

Gouraud shaded sprites. Allegro game programming library.

## 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.
