根据林分三维可视化对树木模型在大小、分级显示LOD、交互、生长的需求,提出一种基于onyxtree的树木模型构建方法。以杉木为例,在Onyx Tree软件输出的初级树木模型将野外实测数据输入到树模型中,修改其外形、树叶长度、疏密等等,然后通过3ds Max软件、PS软件,将野外采集的树皮纹理进行加工,再打开Deep Exploration,将杉木模型修改成实际高度,贴树皮、树叶纹理,最后输出杉木林分三维可视化树木模型。 According to the requirement of three-dimensional visualization of tree models in terms of size, hierarchical display of LOD, interaction and growth, a tree model construction method based on onyxtree is proposed. Take fir as an example, the primary tree model output by Onyx Tree software inputs the field measured data into the tree model, modifies its shape, leaf length, density and so on. Then, through 3ds Max software and PS software, Skin texture processing, and then open Deep Exploration, the fir model modified to the actual height, posted bark, leaf texture, and finally output three-dimensional visual fir tree forest model.
