NAME

       itofix - Converts an integer to fixed point. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       fixed itofix(int x);

DESCRIPTION

       Converts  an  integer  to fixed point. This is the same thing as x<<16.	Remember that overflows (trying to convert an integer greater than
       32767) and underflows (trying to convert an integer lesser than -32768) are not detected even in debug  builds!	The  values  simply  "wrap
       around". Example:

	  fixed number;
	  /* This conversion is OK. */
	  number = itofix(100);
	  ASSERT(fixtoi(number) == 100);
	  number = itofix(64000);
	  /* This check will fail in debug builds. */
	  ASSERT(fixtoi(number) == 64000);

RETURN VALUE

       Returns the value of the integer converted to fixed point ignoring overflows.

NAME

       ex3d - 3d 'bouncy cubes' demo. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example ex3d

DESCRIPTION

       This  program  demonstrates  how  to use the 3d matrix functions.  It isn't a very elegant or efficient piece of code, but it does show the
       stuff in action. It is left to the reader as an exercise to design a proper model structure and rendering pipeline: after all, the best way
       to do that sort of stuff varies hugely from one game to another.

       The  example  first  shows a screen resolution selection dialog.  Then, a number of bouncing 3d cubes are animated. Pressing a key modifies
       the rendering of the cubes, which can be wireframe, the more complex transparent perspective  correct  texture  mapped  version,  and  many
       other.
