三角b样条是计算机图形学和几何建模领域中的一种功能强大的工具。 - 3 - d geometric matching and similarity research aims to achieve recognition , similarity measurement , and matching of 3 - d geometric objects , by means of object analysis , transformation , and feature extraction
三维几何匹配与相似性技术研究是通过对三维几何模型的分析、变换、特征提取等手段来实现对几何模型的识别、相似性度量、匹配等。 - In order to slove collision detection problem in virtual surgery , a fast collision detection algorithm based on oriented bounding box ( obb ) was presented , which simplifies geometric representation to facilitate the process of collision detection between complex geometric objects
摘要为了解决虚拟手术的快速碰撞检测问题，提出了一种新的基于方向包围盒层次树的快速碰撞检测算法，利用简化的几何模型表示一方向包围盒层次树来实现复杂物体间的实时碰撞检测。 - Research result shows that the object - oriented geographic spatial model has stronger representative ability , is easier understood and accepted ; using the concept of geometric data type unify the process method of attribute and spatial data , and simplify entity query and analyses . the topologic relations between entities , which are not been stored in explicit formulation in the model , can be achieved through collective operation of geometric object ' s hypergraph model . compared with traditional his , the query and analyses ability of which based on new model are stronger
研究结果表明，面向对象的地理空间模型具有更强的表现能力，并且容易被理解和接受；采用几何数据类型的概念，可以使对非空间数据和空间数据的处理方法相统一，而且会使对实体的各种属性数据(包括空间属性)的查询和分析模型更加简单；对于面向对象模型中不显式表示的地理实体间的空间拓扑关系，可以利用实体的几何对象的超图模型间的集合运算来求得；基于面向对象地理空间模型的实体查询和分析，也比基于传统gis数据库查询和分析具有强得多的功能。
