NETGEN is an automatic 3d tetrahedral mesh generator
NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen is open source based on the LGPL license. It is available for Unix/Linux and Windows.

FTGL is a free cross-platform Open Source C++ library that uses Freetype2 to simplify rendering fonts in OpenGL applications. FTGL supports bitmaps, pixmaps, texture maps, outlines, polygon mesh, and extruded polygon rendering modes.
Structure Synth generates 3D structures by specifying a design grammar. Even simple systems may generate surprising and complex structures. Structure Synth offers a graphical environment with multiple tabs, syntax highlighting, and OpenGL preview.
The Mesh Viewer is an easy to use lightweight application for displaying three dimensional models (triangular meshes) from a variety of file formats. It uses OpenGL to render the models.
NGSolve is a general purpose Finite Element Library on top of Netgen. With the basic library one can solve heat flow equations, Maxwell equations, and solid mechanical problems. Several add-ons are available for particular application classes. New paper: J. Schöberl: "C++11 Implementation of Finite Elements in NGSolve", ASC Report 30/2014, Institute for Analysis and Scientific Computing, Vienna University of Technology, 2014 http://www.asc.tuwien.ac.at/~schoeberl/wiki/publications/ngs-cpp11.pdf
SDL.NET is a set of object-oriented .NET bindings for the SDL gaming library and provides high-level access to audio, keyboard, mouse, joystick, TTF fonts, various image formats, sound mixing, MPEG-1, and 2D video framebuffer.
The first 3D game engine built in C# for .NET, predecessor to the Visual3D Game Engine (http://www.visual3d.net/game-engine), an All-in-One Game Development Tool for Next-Gen 3D Games, MMOs, Simulations and Virtual Worlds powered by Microsoft XNA.
an interactive 3D viewing program
Geomview is an interactive 3D viewing program for Unix. Geomview lets you view and manipulate three- and higher-dimensional objects, and can also be used as a display engine by other programs to animate objects. Geomview supports OpenGL and uses a Motif X interface.
ShelXle is a Qt GUI for SHELXL
ShelXle combines an editor with syntax highlighting for the SHELXL-associated .ins (input) and .res (output) files with an interactive graphical display for visualization of a three-dimensional structure including the electron density (Fo) and difference density (Fo-Fc) maps. See J. Appl. Cryst. (2011). 44, 1281–1284. for details.
Cross platform 2D game creation framework with Python bindings
FIFE is a cross platform 2D game creation framework written in C++ with Python bindings. It's designed to be flexible enough to support a wide variety of 2D game types but specializes in 2D isometric type views.
This project's aim is to build a 3D simulation environment to control a hexapod, and communicate serially to said hexapod when connected. This way new motion algorithms can be perfected without damaging your robot.
Plate Tectonics simulator
PlaTec is a 2D terrain generator that uses a simplified model of plate tectonics to produce realistic heightmaps in real time. The simulator starts with a flat fractal map and splits it randomly into plates. Plates are moved around the map. If continents of two plates collide, they fold creating mountain belts. If oceanic crust of one plate collides with another plate, subduction occurs resulting in coastal mountain ranges or island chains. This project is part of my Bachelor of Engineering thesis in Metropolia University of Applied Sciences, Helsinki, Finland. The thesis is freely downloadable from http://urn.fi/URN:NBN:fi:amk-201204023993 . A Youtube video showing the simulator in action is available at http://www.youtube.com/watch?v=bi4b45tMEPE .
This is an interactive graphical 3D simulation of the orbital mechanics of the planetary motion in the solar system and galaxy. It specifically concentrates on the phenomenon related to the sun, moon and the earth.
