Products: GTVS - GeoTech Terrain Viewer Suite |

|
GeoTech's Terrain Viewer Suite is a comprehensive package for the creation of
the highly detailed photorealistic "GTVS Terrain" and the modules for utilizing
this terrain, the GTVS modules are:
The robust terrain generation engine is capable of creating and displaying
surfaces generated with hundreds of thousands of triangles and millions of
pixels. For example the terrain below is a 15,000 x 14,000 pixel
Quickbird image (553MB) covering a 150,000 triangle mesh created from the DEM.
This terrain can be flown in real-time at a constant 75 frames per second on an
off-the-shelf PC (Pentium 4, ATI Radeon graphics card).
The generated terrain may be viewed in real-time either as a 3-D model, or it
may be flown in a free-flight mode. With multiple speed control and elevation
locking features, there is no better way to study or display a terrain.

One of the most important points in developing information
systems is the visualization of the concept. Whether you are
planning a land area, or trying to sell it, one of the best ways
to prove the concept is to visualize it. Visualizing your
concept with the help of a real-time flight through user-planned
paths and scenarios will be very helpful in developing the idea
jointly with your customer. Controlling the whole land through a
simple yet powerful user interface will give the feeling of a
real fly-through over the land of your choice.
Have a nice flight with GTVS...

In addition to free navigation, a flight path may be displayed in a looping
demo. Using high-resolutions, anti-aliasing and vertical synching, this mode
offers a very smooth and crisp way of running demonstrations. Both operations
can be rendered in a stereo 3-D format to be viewed with red/cyan glasses.
The main features of the GTVS software are:
- Importing DEM and Terrain Images
- Generating photorealistic terrain
- Creating Flight Paths
- Recording flight videos
- Real-time looping demos of flight paths
- Placing 3-D Objects
- Placing vector layers
The Flight Path Creator provides an
intuitive environment for creating flight paths to be used in
video capture or real-time demos. Multiple screens are used with
a flexible time control to craft flight paths with precision and
ease.
 Video recording of a flight path comes with a number of
controllable parameters to ensure that the final avi can be made
small enough to put online or detailed enough for DVD display.
- Resolutions ranging from 320x240 to 1280x1024
- Frame rate, partial terrain rendering and stereo parameters
- Choice of skydome: clear, dawn, night and sunset
- Compression with the Codec of choice (XVid, Divx etc.)
GTVS has been designed and developed by the Research and
Development (R&D) Department of the GeoTech Group. Mr. Yavuz
Eren is the Head of the R&D Department
