Khayyam is a program for composing 3D scenes for rendering (similar to Poser and DAZ Studio). It can import character and scene models from many model formats (Poser, MD5, BSP, OBJ, 3DS, Collada, and formats used in most Illusion games). There is support for basic object placement, scaling, posing skeletal characters, and lighting. Scenes can be exported in POV-Ray format for rendering. Khayyam is implemented as a shell program using many libraries from the Floyd and Sodipodi projects.
NeoTextureEdit is an easy to use graph-based procedural seamless texture editor. NeoTexture is the associated run-time generation library. Using continuous basis functions, it can generate arbitrary resolution images without quality degradation. Its main purpose is to produce high-quality textures for real time rendering applications that can be stored in a few kB and synthesized on application startup. But it can also be used to generate off-line images.
Zaz is an arcade action puzzle game where the objective is to get rid of all incoming balls by rearranging their order. Currently it includes 20 different levels and two modes of gameplay. The engine allows for easy custom level creation with unlimited number of paths, different speeds, ball-sizes, and rules. A 3D accelerator is needed for decent gameplay.
CorsixTH is a clone of Theme Hospital. As computers evolve, we risk losing some classic games. Bullfrog's Theme Hospital, published in 1997, is a classic simulation game, but getting it to run natively on modern operating systems is getting progressively harder. CorsixTH aims to reimplement the game engine of Theme Hospital, and to be able to load the original game data files. This means that you will need a purchased copy of Theme Hospital, or a copy of the demo, in order to use CorsixTH. After most of the original engine has been reimplemented, the project will serve as a base from which extensions to the original game can be made.
Angel is a 2D game prototyping engine based on OpenGL and C++. It was originally made by a group of employees at Electronic Arts Los Angeles for use in a GameJam they were planning for April of 2008. Angel provides many useful functions for prototyping gameplay, including simple physics, particles, text rendering, sound, input mappings, config files, pathfinding, and Python scripting.
Octaspire Crates! is a scriptable, skinnable, extensible, and relocatable 3D action puzzle game. All the missions, game entities (or crates), game states, and configuration of the game engine are implemented as plain text Lua-scripts. So, if you know Lua, you can write new game entities, game states, missions, and levels with any text editor, without any special development tools. New skins can be created with any image editor that can save .png images, dropped into a new subdirectory under the resources/textures directory, and changed in the configuration file config.lua. Crates has also its own (simple) implementations for all the different container classes it needs (like vector, string, and so on) to keep the external dependencies fewer.
