Open Source Cygwin 3D Modeling Software

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.

The ObjectVolume program calculates the volume, surface area and centroid of a closed triangular mesh represented in an object file (.obj). The process goes through the list of triangles that make up the surface and, for each triangle, forms a tetrahedron with an external point. The program uses the origin (0,0,0). The volume of the tetrahedron is then calculated. Tetrahedrons with back facing triangles are added and those with forward facing triangles are subtracted yielding the object volume. A detailed description of the process is presented in the ObjectVolumeTutorial.doc document as well as program logic and results. A key component in the program is a subroutine that calculates the volume of a tetrahedron. Four sets of equations were tested and to my surprise all four produced similar results in accuracy and timing.

Generate 3d steroscopic image easily just by giving left and right image. Input image can be jpg, png, bmp, etc. Output format is uncompressed bitmap image.

NOTE: Use Fltk_Contour insted this code! FMesh is a simply scientific data visualization tool based on OpenGL. FMesh can generate 2D and 3D graph of contour and color maps for any (x,y,z) scattered data set, many other options are included.

A library for volume and three-dimensional boundary representation, providing methods for the creation and manipulation of those structures.

(Moved to http://code.google.com/p/igb/) Vigo::3D is a library for multi-agent simulation and visualization in 3D space.

Y.A.P.R.M. is a free-as-in-freedom modeller to graphicaly design 3d scenes and generate POV-Ray-files for them. Appart from the basic POV-Ray objects which can be used in CSG operations it supports spline based objects. Furthermore a vast amount of 3d-files can be imported and used with Y.A.P.R.M.

A suite of plug-ins for the 3D modeling software Realsoft 3D that enables creation of new cities and other models for the Microsoft game "Midtown Madness 2".
