Search and Render Algorithm for Three-dimensional Terrain Visualisation of Large Dataset

摘要

There exists a wide class of algorithm for 3-D modelling and visualisation of terrain. These techniques are not very useful for flight simulation application. A very large terrain has to be modelled for flight simulators and primitive techniques do not support large data handling. The terrain keeps on changing rapidly, so in flight simulator application, rendering of each frame must be very fast. This paper describes an algorithm which handles very large dataset and can generate 3-D frames quickly. A flight simulator application can be designed using this technique.
