Image Navigation in 3-D Space
This Windows NT-based software uses satellite imagery and user actions to render the image on to the computer screen. It offers manual and auto modes of navigation. In manual mode, user can change the viewing direction, and position of the viewer using the mouse control. In auto mode, user first selects the route of navigation then using auto run panel starts auto navigation. Different views, like left view, right view, rear view can be selected during navigation in both the modes. Facility to simulate day/night conditions, weather conditions is also available. On the basis of these variables, the frame generator renders the scene. This software uses the powerful graphics library of OpenGL, thereby automatically using the available hardware to enhance the performance or otherwise emulates the functioning through software.
