Research of Large-Scale Terrain Data Organization Method in Virtual Reality

Summarized the mainly algorithms of terrain three-dimensional visualization in virtual reality, for the large-scale terrain data organization in three-dimensional virtual war zone simulation, analyzed the characteristic of change of scene, according to motion regulation and idea of layer and block, presented the organize principle of external static data and terrain blocks index regulation, for the large system pressure in the process of scene update, synthesize available visibility culling methods, for the scene change with large-scale data, the system could operate in a high frame rate.
