pointed tree meaning in English
尖顶树
Examples
- View dependent sequential point trees
视点相关的顺序点模型树 - Sequential point trees provide the state - of - the - art technique for rendering point models , by re - arranging hierarchical points sequentially according to geometric errors running on gpu for fast rendering
一般地，点模型以层次化树结构的方式对模型进行由粗至细的多分辨率表示，以方便多分辨率的绘制。 - 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。 - 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。
