Open source (free) 3D (terrain, game) GIS Platform Based on. NET (C #)
Axiom: open-source 3D game engine. It is the. Net version of the famous open-source engine ogre.Source codeFully constructed using C #, mainly for the graphic part.
Realmforge: open-source 3D game engine. The graphic part adopts axiom and is combined and rewritten by some other modules such as network and AI. It is fully constructed by C.

Axiom
The axiom 3D engine is an open-source, cross-platform 3D Graphics Rendering Engine. net and mono. the engine is a high-performance C # port of the powerful ogre engine. its flexible component-oriented architecture allows easy extension and provides full support for both DirectX and OpenGL. the engine is also cross platform supporting both Windows and Linux operating systems.
Realmforge:
The. net 3D Game Engine predecessor to visual3d. net (www.visual3d.net), which is a framework and toolset for the visual design and development of 3D games, simulations, and interactive environments using C #,. NET 2.0, and xNa.
Irrlicht
The irrlicht engine is an open source high performance realtime 3D engine written and usable in C ++ and also available. net ages. it is completely cross-platform, using d3d, OpenGL and its own software Renderer, and has all of the state-of-the-art features which can be found in commercial 3D engines.
We 've got a huge active community, and there are lots of projects in development that use the engine. you can find enhancements for irrlicht all over the web, like alternative terrain renderers, portal renderers, exporters, world layers, tutorials, editors, language Bindings for Java, Perl, Ruby, basic, python, Lua, and so on. and best of all: it's completely free.
Non-. NET platform
Orge: highly open-source 3D Game Engine. Built using C ++, mainly for the graphic part.

Terravisiontm is an open source distributed, interactive terrain visualization system developed by SRI International. it allows users to navigate, in real time, through a 3-D graphical representation of a real landscape created from elevation data and aerial images of that landscape. there are using terrain visualization tools on the market, but here are some of the features that make terravisiontm unique:
New: Full Open Source hosted on SourceForge.
Terravisiontm can browse huge datasets, in the order of terabytes.
All data can be distributed over multiple servers accessing ss the web.
3-D OpenGL and geovrml models can be overlaid, e.g. Buildings, wind vectors, etc.
Terravision can access OGC web map servers (WMS) [more]
Datasets of different size, resolution, source, and coordinate system are supported.
New: terravision server on Internet2.
Available for free for Windows, Linux, and SGI platforms.
New: version 6.0 released
