四元樹
  1. 24 frisken s f, perry r n. simple and efficient traversal methods for quadtrees and octrees. j. graphics tools, 2002, 7 : 1 - 11. 25 zhang h, hoff k. fast backface culling using normal masks

    實驗表明,新方法能將順序點模型樹的繪制效率提高20 % 64 . 6 % ,並且越近觀察模型或模型中的遮擋關系越復雜時,新方法的加速比更高。
  2. A view - dependent multi - resolution terrain simplification based on adaptive quadtrees

    基於自適應四叉樹視相關的多解析度地形簡化
  3. In this disseytation, we present a new algorithm of view - dependent multiresolution terrain simplification based on adaptive quadtrees. especially, we discuss these main problems in multiresolotion terrain rendering such as levels of detail mesh generation, vedex evaluating and er

    最後,將該演算法應用於dem地形模型簡化中,簡化前的地形繪制幀速率為4fps ,簡化后的地形繪制幀速率為70fps左右,在繪制圖象質量沒有明顯退化的前提下,能滿足視覺和實時劃覽的需要。
