Three-dimensional visualization models for extra large scale landscape geomorphology are the important parts of VR system platforms.

Interactive navigation of very large-scale terrain environment involves many difficulties because of its out-of-core geometric data and texture, which can not be wholly loaded into the internal memory.

For mass dataset terrain, the contradiction between the finite process ability of hardware and the increasing mass dataset in flight simulation was solved by adopting to schedule them in blocks and revise them real time.

It is used for detecting and tracking the infrared target in super field of view infrared image.
