Open Source Tcl 3D Modeling Software

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.

The Open-Source PyMOL repository has been moved to github: https://github.com/schrodinger/pymol-open-source We still use the pymol-users mailing list here on sourceforge. Please subscribe for community support: https://pymol.org/maillist (Note: SourceForge email newsletter and special offers are optional and can be unchecked) The PyMOL community wiki has its own home: https://pymolwiki.org/

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

surfit is an open source and free gridding and contouring software. surfit can do interpolation/approximation of points, contours and surfaces, can take fault lines and trend surfaces into account, can use inequalities and other conditions. Supports a lo

Ayam is a free 3D modelling environment for the RenderMan interface.

GNU Autoconf, Automake and Libtool scripts and makefiles for the Open CASCADE solid modeler. http://www.opencascade.org

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.

Dynamically loadable modules for TclTk, Perl, Python to ease the task of building custom 3D modellers and rendering engines.

The 3D Slicer is freely available, open-source software for visualization, registration, segmentation, and quantification of medical image data. Follow the link for more info: http://slicer.org

Half-Edge implementation, plus various utilities like silhouette edges and triangle-stripping

A work-in-progress LDraw.org parts author's CAD program. Currently only a simple renderer. But progress is being done..

A device server inteded for (but not limited to) use with 3D input devices (like dynasight, Polhemus FASTRAK, motionstar and the magellan spacemouse). Devices can be configured via a remote TCP connection. Device data is sent to registered clients via

Command line application that enables you to create wide range of domes, vaults, tubes or egg-like shapes from triangular desks. The arch is always in the shape of catenary that makes it possible to design and build extremely tough models or buildings suitable for underground/underwater architecture. The program has two outputs. The first is OBJ file you can import to 3D modelling software, such as Autocad or Blender. The second output is CSV file you can open in OOCalc or Excel and use as plans for actual construction. The application is written in Tcl and released under WTFPL.
