PyMOL is an OpenGL based molecular visualization system
PyMOL is a Python-enhanced molecular graphics tool. It excels at 3D visualization of proteins, small molecules, density, surfaces, and trajectories. It also includes molecular editing, ray tracing, and movies. Open Source PyMOL is free to everyone!
The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.
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.
Ayam is a free 3D modelling environment for the RenderMan interface.
gMax graphic tools for jMax
Powerful platform for creating networked multiplayer 3D games. The system includes specifications for a client engine and 2 protocols. Demo apps: mud/moo proxy, tetris. Currently uses OpenGL, VRML, java, tcl. Client/server architecture for security.
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.
Liam3 is a framework linking several external software to provide a MABS development environment for situated 3d agents and to display these agents in a real time 3d rendering engine. Initially it is linking MadKit and The Nebula Device.
It is an extension of Wish to Tcl/tk and includes a new widget called glview. Each glview widget can draw a 3D view and does OpenGL work in Tcl/Tk, a high-level language, if Tcl is Operating System independent then we can build OpenGL applications independent of the operating system.
Open Source and Portable object oriented software for 3D digital image segmentation and visualization. Pipes and Filters Architechture. Implemented in C++, and uses FLTK, VTK, ITK, TCL (plugins), and pipeline filters implemented in XML. DICOM support.
