G3D is a commercial-grade C++ 3D engine. It is used in commercial games, research papers, military simulators, and university courses. G3D supports real-time rendering, off-line rendering like ray tracing, and general purpose computation on GPUs.
As of January 16, 2018, SourceForge is again the home of the active repository for G3D.
VRG3D is a library that uses G3D and implements a minimal set of features required to run applications written with G3D in projection based virtual reality environments, such as Caves and Fish Tanks.
3D grid toolbox for analysis of molecular simulations
...Currently, the tools only work with the simulation trajectories generated by the GROMACS simulation package (http://www.gromacs.org/).
The generated density maps are saved in the Grid3D native .g3d format and can be visualized using a third party data visualization software. A converter from the .g3d format to .vti, an XML based format of the VTK library is provided with the "Grid3D Toolbox", so that the generated density maps can be visualized using the ParaView data analysis and visualization software (http://www.paraview.org).

This project is intended to all the 3Ds Max(c) users, who are looking for a Open Source project, with the same GUI, and in other platforms like Linux or OS X.
g3d is an experimental xml file format for 3d data. An open format not tied to a particular engine or graphics tool gives flexibilty to reuse and repurpose data, and develop platform and project independant tools.
