Maxwell Render for Blender
B-Maxwell add-on offers seamless integration with Maxwell Render and Blender
The Python Computer Graphics Kit is a collection of Python modules that contain the basic types and functions to be able to create 3D computer graphics images (focusing on Pixar's RenderMan interface).
Graphic library for Java that supports displaying and manipulation of vector/raster/3d graphic. Currently under development (lots of changes, not for end-user).
V-Ray integration to Blender
LdGlite exists to render images of models made out of Lego bricks in a platform independent manner. It requires the LDRAW brick library and uses OpenGL as the graphics engine.
Cal3D is a skeletal based 3d character animation library written in C++ in a platform-/graphic API-independent way.
GLGraphics is a library for the Processing programming language that offers a number of classes to simplify the handling of OpenGL textures, GLSL shaders and off-screen rendering inside Processing.
3D Charts - Templates for PovRay(TM)
Here are PovRay(TM) templates for creating amazing 3D plots (histogram, surface, box&whisker). These are macros in PovRay Scene Description Language (SDL), you have to #include into Your scene, manually or by PovEdit Menu System. Nice renderings!
tkBacktracer is a cross-platform interactive visualization tool to explore the tool motions in RS-274D "G-code" CNC files used in computer controlled milling and manufacturing.
AKtive Media is an ontology based cross-media annotation (Images and Text) system. Our goal is to automate the process of annoation by suggesting knowledge to the user in an interactive way while the user is annotating and hence minimizing user effort.
InnerWorld is a landscape builder for Blender, the 3D modeling tool. Using a graph editor terrains can be generated from Blenders noise functions and from external sources. Objects can automatically placed dependent of the terrains geometry.
sql2diagram converts sql scripts to diagrams in the XML format dia, which can be viewed and further maintained with the dia drawing program. It is a good help for the documentation of a database structure. It provides HTML output as well.
DarkMaps is a program that reads images and builds a 3D map from them.
Distriblend (originally NetBlend) is a system for rendering 3D scenes over a network using the popular 3D editing and rendering application Blender.
LDrawLoader is an implementation of the com.sun.j3d.loaders.Loader-interface to load LDraw-parts and -models into Java3D-Scenes. Additionally a LDraw-Viewer is provided, that uses the loader to display LDraw-parts and -models.
Panorama is a framework for 3D graphics production. This will include modeling, rendering, animating, post-processing, etc. Animation is not currently supported, but will be added soon. It is officially part of the GNU project.
IMPFarm is a renderfarm for the POV-Ray raytracer. All communication is via http with XML documents. Servers and clients are cross platform. Management and reporting is done using web pages.
yadra - yet another distributed rendering application A Network-Render-Tool for Blender. A Java based, platform-independent tool, for rendering animations of blender in a network. Easy setup (no SMB/CIFS-Connections). Web-Interface.
3D Graphics engine on Pure Java 2. Small and Fast. Open Source.
B-Reality is a 3D game or real-time simulation engine. It is centered on physic simulation: every object in a scene is animated in function of its physic properties and forces applied on it.
Python based application to render in background Blender projects (still images or animation). It provides also a server for remote control such as checking the render status or cancel/submit new jobs. Msi available for windows.
A library in the tradition of openGL and glut that makes it easy to use 3D skeleton objects (like robots, ships, people etc) in openGL programs. Currently the objects are best created with Glazier (glazier.sourceforge.net)
