模型树 meaning in English
model navigator
model tree
Examples
- This paper presents a view dependent method to augment sequential point trees by embedding the hierarchical tree structures in the sequential list of hierarchical points . by the method , two kinds of indices are constructed to facilitate the points rendering in an order mostly from near to far and from coarse to fine
为此，我们提出视点相关的顺序点模型树，将层次化的树结构嵌入点的顺序化线形序列中，并生成两种索引以方便对点数据进行由近及远和由粗至细的处理。 - After studying parts manufacturability knowledge and parts themselves , summed up rotational parts " feathers and their parameters , advanced all kinds of information that the part ' s molding should be included , then gave the structure of the part ' s molding . the reasoning engine is designed with mixed reasoning direction , it uses part ' s feature - based molding tree as its facts
在对零件特征和对零件的可制造性分析知识进行研究的基础上，标准化了回转类零件在可制造性分析系统中的各类特征及其参数，提出用于可制造性分析的零件特征模型应包含的各类信息，进而给出零件特征模型树的结构。 - As a result , invisible points can be culled view - dependently in high efficiency for hardware acceleration , and at the same time , the advantage of sequential point trees could be still fully taken . therefore , the new method can run much faster than the conventional sequential point trees , and the acceleration can be highly promoted particularly when the objects possess complex occlusion relationship and viewed closely because invisible points would be in a high percentage of the points at finer levels
具体地说，从根结点开始，我们将点模型树按照广度优先的方式一层结点一层结点地顺序排列在排列一层结点时，我们引入迭代的z型序列来安排这些结点在序列中的位置，使得空间上邻近的点在序列中的位置也是靠近的而在每个非叶子结点，还记录它的儿子结点在序列中所处的片段位置。
