We do computer graphics, 2D and 3D geometry modeling, computer-aided design (CAD), & more.

This is the place to be if you love or want to learn more about computer graphics, 3d printing, 2D and 3D geometry, solid modeling, CAx (CAD/CAM/CAE/etc), visualization, and high-performance computing!

We are part of a large open source community that makes tools to help you make and analyze things. CAx software is fundamentally different from content modeling software such as Blender, Maya, and 3D Studio used for making movies and pretty pictures. CAx software like AutoCAD, Pro/Engineer, CATIA, and BRL-CAD are for everything else. Our primary development focus areas include:

  • CAD (design),
  • CAM (manufacturing),
  • CAE (engineering),
  • solid modeling (analysis), and
  • computer graphics (visualization).
