excamera - Viewing a 3d world from an arbitrary camera position. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example excamera DESCRIPTION
This program demonstrates how to use the get_camera_matrix() function to view a 3d world from any position and angle. The example draws a checkered floor through a viewport region on the screen. You can use the keyboard to move around the camera or modify the size of the view- port. The keys that can be used with this example are displayed between brackets at the top of the screen. SEE ALSO

exzbuf - Z-buffered polygons demo. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example exzbuf DESCRIPTION
This program demonstrates how to use Z-buffered polygons and floating point 3D math routines. It also provides a simple way to compute fps (frames per second) using a timer. After selecting a screen resolution through the standard GUI dialog, the example shows two 3D cubes rotating and intersecting each other. Rather than having full polygons incorrectly overlap other polygons due to per-polygon sorting, each pixel is drawn at the correct depth. SEE ALSO
