In p, a bunch of particles interact with each other according to this simple rule: every particle moves towards, away, or watches other particles. When the program starts, each particle chooses a random color, position, and the particles with which it will interact. As the program runs, some particles join together to form a train and journey together thereafter. Some orbit each other. Some collapse into each other. Some form swarms that split and join. One cannot predict when or where or how many of these behaviors will emerge, but they usually do.
The Pure Perl RayCaster is a small simple ray-casting application written completely in Perl without using OpenGL or any other 3D API library. For the GUI, it uses wxPerl. It can load a 3D object from a file (in RAW format), display the object in wireframe perspective view, allow you to orbit and zoom your camera, and produce a user defined size ray casting image of the current view in a predefined color theme, with or without smooth shading. It is well suited for educational purposes, in order to study, understand, tweak, and try well known fundamental 3D computer graphics techniques.
PCity is a procedural city generator. It uses a configuration file and few maps (e.g. population density or a height map) and can be tuned via various parameters. Its features include street network generation, building generation, texture generation from a texture library, and a visualization engine.
MeshLab is an open, portable, extensible system for the user-assisted processing of unstructured 3D meshes. The system is aimed to help the processing of 3D models arising in 3D scanning, providing a set of tools for cleaning and healing this kind of meshes. The system is heavily based on the VCG library developed at the Visual Computing Lab of ISTI - CNR, for all the core mesh processing tasks.
CryptEngine is a fast 3D engine for Java. It is based on OpenGL and provides components and objects allowing the description and rendering of 3D scenes. Unlike several other 3D engines, it focuses on rapid application development and makes it possible to create and render complex 3D scenes without having to learn OpenGL. A large collection of demos are included, demonstrating the many features and providing you with valuable design techniques and tricks. It also facilitates game design with a sound system, scripting, and networking.
Libg3d is a glib-based library for loading and manipulating 3D objects. It supports a wide range of file formats for 3D objects and textures. Its plugin interface makes it easily expandable. The code has been split off from the g3dviewer project, which now depends on this library.
