户外场景中的树木三维模型多层显示法

Multi-scale indication method of 3-Dform of trees for evaluation of outdoor scenery

提出了一个能根据视距变化作出有效的多层显示的树木三维建模方法。具体有以下两个步骤:通过投票算法获取树木的三维概形;通过八叉树来实现三维形态的分级多层显示。

At present, the extended-reality technology to synthesize real scenery and an imaginary scenery has been attracted a great deal of attention. In the evaluation of natural scenery, a real representation of three-dimensional form of the tree occupies an important position. We proposed the hierarchical multi-scale modeling method of the trees for efficient indication corresponding to the change in viewing distance. The concrete steps as following: 1) Acquisition of the outline form of trees by the voting metho...
