交运算 meaning in Chinese
meet (mathematics)
Examples
- An efficient rejection test for ray triangle mesh intersection
一种用于光线与三角形网格求交运算的有效剔除算法 - Then curvatures and highlight lines are used to estimate fairness of curve and surface respectively
在船体曲面造型设计中，常用到曲面与平面的求交运算。 - The integral area ' s shape can be arbitrary , its shape is the intersecting part of physical grid and mathematics grid , so , the generation of integral area of unit is an intersection operation of two polygons
摘要由数学覆盖和物理网格形成的流形单元的积分区域可以有任意形状，其形状为物理网格和数学网格的相交部分，所以流形单元积分区域的形成为两个多边形（数学网格和物理网格）的求交运算。 - The main conclusions are as follows . firstly , among operations of fuzzy relations , the inverse does not change any transitivity at all and the complement changes some transitivity properties whereas the operations union and intersection fail to preserve most transitivity properties . secondly , we carry out a detailed investigation into the relationships of t - transitivity , negative s - transitivity , r - s - semitransitivity and t - s - ferrers properties under some conditions , such as completeness , strong de morgan triple , positive / - norm etc . , and have some expected conclusions
其研究内容与结果归纳如下：首先，通过对模糊关系运算的传递性讨论，我们得到，若一个模糊关系具有某种传递性，则其逆关系不改变其传递性性质，余关系仅改变一些第一类传递性性质，不改变第二类传递性性质；若两个模糊关系具有某种传递性，它们的模并、模交运算不保持大多数传递性性质。 - In some time - critical situation , continuous ssi is computation bottleneck of some solid modeling system . conventional approach for solving continuous ssi often uses intersection algorithm iteratively without taking the characteristic of the surface into account to simplify computation . the dissertation analyzes the intersect curve structure of continue surface , from the point of intersect curve ' s evolution , it describes the relationship between topology of offset surface intersect curve and topology transmit point ( ttp )
等距曲面和运动曲面在cad cam领域中有着重要的应用，在一些时间敏感场合例如数控加工动态仿真，等距曲面和运动曲面等连续变化曲面求交运算已成为这些系统的计算瓶颈，连续变化曲面求交问题的通常解法是采用曲面求交算法反复迭代计算交线，没有考虑连续变化曲面交线之间的相似性进行求交简化，效率上一直不能有很大的提高。
