Raw Normal View History

/**
* program : glutmech V1.1
* author : Simon Parkinson-Bates.
* E-mail : sapb@yallara.cs.rmit.edu.au
* Copyright Simon Parkinson-Bates.
* "source if freely avaliable to anyone to copy as long as they
* acknowledge me in their work."
*
* Funtional features
* ------------------
* * online menu system avaliable by pressing left mouse button
* * online cascading help system avaliable, providing information on
* the several key strokes and what they do.
* * animation sequence coded which makes the mech walk through an
* environment. Shadows will soon be added to make it look
* more realistic.
* * menu control to view mech in wireframe or sold mode.
* * various key strokes avaliable to control idependently the mechs
* many joints.
* * various key strokes avaliable to view mech and environment from
* different angles
* * various key strokes avaliable to alter positioning of the single
* light source.
*
*
* Program features
* ----------------
* * uses double buffering
* * uses display lists
* * uses glut to manage windows, callbacks, and online menu.
* * uses glpolygonfill() to maintain colors in wireframe and solid
* mode.
