/*****************************************************************************
* Title: GLBoing
* Desc: Tribute to Amiga Boing.
* Author: Jim Brooks <gfx@jimbrooks.org>
* Original Amiga authors were R.J. Mical and Dale Luck.
* GLFW conversion by Marcus Geelnard
* Notes: - 360' = 2*PI [radian]
*
* - Distances between objects are created by doing a relative
* Z translations.
*
* - Although OpenGL enticingly supports alpha-blending,
* the shadow of the original Boing didn't affect the color
* of the grid.
*
* - [Marcus] Changed timing scheme from interval driven to frame-
* time based animation steps (which results in much smoother
* movement)
*
* History of Amiga Boing:
*
* Boing was demonstrated on the prototype Amiga (codenamed "Lorraine") in
* 1985. According to legend, it was written ad-hoc in one night by
* R. J. Mical and Dale Luck. Because the bouncing ball animation was so fast
* and smooth, attendees did not believe the Amiga prototype was really doing
* the rendering. Suspecting a trick, they began looking around the booth for
* a hidden computer or VCR.

GlfwExamples
http://www.taoframework.com
Copyright ©2003-2004 Randy Ridge, All rights reserved.
These are C# ports of some OpenGL examples developed for GLFW, the originals
are available from http://glfw.sourceforge.net.
These examples use Tao.OpenGl and Tao.Glfw. Make sure you have the
appropriate native GLFW libraries for your system installed.
These examples are fairly well documented, however, do not take
them to be 'best practices' for .NET OpenGL development. The
intent of these ports is as an introduction or as a comparison
against the original native versions.
If you'd like to contribute you can port the remaining examples as supplied
with GLFW. I never got around to them, but they look pretty trivial.

Change Log:
April 23, 2004:
Initial release, version 1.0.0.0.
