Highly optimized 2D|3D math library, also known as OpenGL Mathematics (glm) for `C`. cglm provides lot of utils to help math operations to be fast and quick to write. It is community-friendly, feel free to bring any issues, bugs you faced. Almost all functions (inline versions) and parameters are documented inside the corresponding headers. OpenGL-related functions are dropped to make this lib platform/third-party independent. Make sure you have the latest version and feel free to report...
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.
Earth orbits and satellite coverage display in 3D on your laptop.
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.
TactileImage is a simple crossplatform 2D-to-3D converter (currently jpeg to stl). It enables a blind person to "see" (to feel by a tip of a finger) the images - when printed on 3D printer. It could also be used for creation of terrain in 3D games

C++ wrapper and extension of OpenGL. Provides Scene Graphing natively and cross-platform development through "glue" libraries. "glues" available so far; Qt, X11, GLUT, SDL, Allegro (with AllegGL ), with Win32 to come. Base library depends on OpenGL only.
BLIX is a cross-platform set of Python extension modules and Python scripts for Blender (www.blender.org). These scripts add camera calibration, 3D reconstruction and rigid body orientation to Blender.
Crossplatform raytracer that accepts scene description scripts written in GML. The scripts have the ability to handle functions, recursion and binding.
