Open Source (free) three-dimensional (terrain, gaming) GIS platform under the. NET Platform

Open source 3d (Terrain,game) GIS platform based on. NET (C #)

Axiom: Open source 3D game engine, is the famous open Source Engine ogre. NET version. The source code is constructed entirely in C #, mainly in the graphics section.
Realmforge: Open source 3d game engine, the graphics part of the axiom, and the combination and write some other network, artificial intelligence and other modules, completely by C # constructs.

Axiom
The Axiom 3D engine is a open-source, cross-platform 3D Graphics Rendering Engine for. 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 a 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 in teractive environments using C #,. NET 2.0, and XNA.

Irrlicht
The Irrlicht engine is a open source high performance realtime 3D Engine written and usable in C + + and also available for . NET languages. It is completely cross-platform, using D3D, OpenGL and its own software renderer, and have all of the State-of-the-art feat Ures which can be found in commercial 3d engines.
We ve got a huge active community, and there is lots of projects in development so use the engine. You can find enhancements-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

Terravisiontm is a Open Source distributed, interactive terrain visualization system developed by SRI International. It allows users to navigate, in real time, through a-Z graphical representation of a real landscape created from Elevati On data and aerial images of this landscape. There is many terrain visualization tools on the market, but here is 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 is distributed over multiple servers across the WEB.
GEOVRML VRML and 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 Windows, Linux, and SGI platforms.
New:version 6.0 released
