Explore 3D terrains with this tool. TNTsim3D for Windows is a FREE standalone program that lets you fly over 3D terrains with keyboard or joystick controls. Use the professional TNTmips software to prepare Landscape Files (.sim) for TNTsim3D from objects in your TNT Project Files (.rvc). The TNTmips data preparation step (Support / TNTsim3D Landscape Builder) creates a terrain object and a texture object which are specially optimized for real-time interactive 3D simulation. The terrain and texture objects are bundled together in a Landscape File (.sim).

The ideal way to visualize the true shape of your geospatial data is to combine the data with an elevation model and "fly" over and around a 3D scene, examining features from any vantage point in real time. TNTsim3D for Windows allows you to move over 3D terrains using joystick, keyboard, or mouse controls. You can control all aspects of the viewer orientation (attitude), height above the surface, and speed. Special visual effects are also available, such as automatic texture smoothing and atmospheric effects (fog / haze).

Prerequisite Skills TNTsim3D is easy to use even if you have no previous experience with geospatial analysis software. If you have used a flight simulator software program and have a joystick, you are already familiar with moving through a simulated 3D scene. But even those without a joystick can use the keyboard to easily control movement, speed, and attitude.

Sample Data The exercises presented in this booklet use sample data distributed with the TNT products. If you do not have access to a TNT products CD, you can download the data from MicroImages' web site. In particular, this booklet uses sample files in the TNTSIM3D sample data directory. Many other sample landscape files are available for download from MicroImages' web site.

More Documentation This booklet is intended only as an introduction to the features of TNTsim3D for Windows. For information about creating Landscape Files for use in TNTsim3D, consult the Tutorial booklet entitled Building 3D Landscapes.

TNTmips and TNTlite TNTmips comes in two versions: the professional version and the free TNTlite version. If you did not purchase the professional version (which requires a software license key), TNTmips operates in TNTlite mode, which limits object size and enables data sharing only with other copies of TNTlite. TNTsim3D is a free product that works identically with either TNTmips or TNTlite, but it can be used only on Windows computers.

Requirements:
* Be sure you have installed the most recent version of DirectX or OpenGL for your version of Microsoft Windows
* The most recent drivers for your video display board

The license of this software is Freeware, you can free download and free use this 3d graphic software.
