Open Source Solid Modeling CAD
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.
Ayam is a free 3D modelling environment for the RenderMan interface.
Converts between many 3D data formats
IVCon-TL can read and write a variety of 3D graphics file formats, converting from one to the other. Supported formats include 3DS, ASE, BYU, DXF, GMOD, HRC, IV, OBJ, OFF, POV, SMF, STL/STLA/STLB, TEC, TRI/TRIA/TRIB, UCD, VLA, WRL/VRML, XGL and more.
KLevel is a heightfield modelling tool designed to mimic Leveller for Windows. It features an OpenGL preview and many brush-like tools.
Magneticle is a 3D OpenGL physical simulation that applies the Biot-Savart law to charged particles operating inside a magnetic field produced by a current-carrying wire modeled as an arbitrary space curve.
POVLAB is a full 3D graphic modeller,which models 3D objects for the photo-realistic Špovteam Persistence Of Vision Raytracer (POV-Ray).
3D Modeling application based on OpenGL for Linux, OS X and Windows.
This library contains two classes vtkQGLRenderWindow and vtkQGLRenderWindowInteractor which allow one to use VTK with the QGLWidget extension of QT. In other words, these classes can be used to build QT applications which utilize the facilities prov
