Design and Display Happy Cube solutions
The Happy Cube Solver is an interactive environment based on OpenGL for designing and building cubes and other designs from the Happy Cube 3D puzzles. It integrates a graphic engine for creating and viewing designs and a powerful AI engine for solving them. Using this program automatically implies that you respect the copyrights on the Happy Cube©® Puzzles. This program is indented to support you while playing live with the Happy Cube©® Puzzles. These puzzles are worldwide manufacturered by HAPPY bvba, Belgium, on licensed and thus restricted base (www.happy.be). The Happy Cube puzzles are the result of a real invention in 1986 by Dirk Laureyssens. This means that using the puzzle snits as well as puzzle piece shapes to create or manufacture your own puzzles is illegal and against law, since the Happy Cube Puzzles are worldwide protected by many US copyrights since 1987.
OpenB3d is a library that allows easy access to 3d features of OpenGL, and quick game development
A tool for finding missing or corrupt images in a sequence. Also generates basic statistics from Exif data. Targeting time-lapse and render-farm users when using post-processing tools such as After Effects.
Realtime 3D game/visualization engine, written in C++, scriptable through Tcl/Tk, Python and Lua. Supports D3D and OpenGL for rendering, runs under Linux and Windows.
Lightfeather is a 3D engine for Linux, Mac OS X and Windows. It is designed to be easy to use but still take advantage of the features of modern graphics hardware.
Klimt (formerly known as SoftGL) is a 3D library with a similiar API to that of OpenGL and OpenGL|ES, targeted for mobile devices. We are searching for developers. If you want to join send an email to the project leader.
