Taken the poyang lake region as test site, we firstly build the lod models ( including terrain and culture feature data ) based on viewpoint. secondly, we adopt active surface definition, a real - time framework, to manage the terrain data, and then apply clip texture to efficiently manage the high - resolution textures. thirdly, the parallel processing technology is used to deploy the scene database dynamically and optimize real - time simulation graphics, which result in higher fidelity and better simulation effects in the virtual scene we finally built up
首先建立基於視點的lod模型（包括地形和地物） ，然後採用活動表面定義（ activesurfacedefinition ）這一實時架構來管理地形數據的調度，並結合剪切紋理（ cliptexture ）技術對高解析度紋理數據進行有效的管理，以及利用并行處理技術對場景數據庫進行動態調度管理和實時模擬圖形優化處理，從而建立真實感強、模擬效果佳的大規模虛擬場景，有效地解決了這一問題。
