Open Source Solid Modeling CAD
BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.
Creates 3D models from photographs
Regard3D is a free, multiplatform, open-source structure-from-motion application. It creates 3D models of objects, based on photographs from different angles.
VPython is an easy-to-use 3D graphics module for Python.
First-person 3D building and elevator simulator
Skyscraper is a fully featured first-person 3D virtual building simulator, written in C++ and using the OGRE graphics engine (previous versions used Crystal Space). It's flagship feature is an elaborate and realistic elevator simulator.
Structure Synth generates 3D structures by specifying a design grammar. Even simple systems may generate surprising and complex structures. Structure Synth offers a graphical environment with multiple tabs, syntax highlighting, and OpenGL preview.
Maxwell Render for Blender
B-Maxwell add-on offers seamless integration with Maxwell Render and Blender
NOTE: Codebase is being moved to it's new home at: https://github.com/cjcliffe/CubicVR A high-performance object-oriented OpenGL 2.0 & OpenGL ES 3D engine with a simple implicit library interface. Includes GLSL, Bullet physics and Lua scripting.
Discrete-event simulation library.
This project's goal is to develop and maintain a high-quality, 3D, physics-enabled, discrete-event simulation library that can be used for industrial simulation projects in an engineering and/or manufacturing environment.
Development has ceased.
With Tabasco you can create textured TAb-BASed Cut-Out-sheets of any textured 3D-Model given in VRML97 file format. Those are unfolded automatically and optimized to make the reassembling of the textured papermodel as easy as possible.
