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.

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.

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

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

...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.

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.
