| 摘 要： | 图形处理、显示速度与数据量之间的矛盾(简称时空矛盾)能否缓解一直是OpenGL仿真成败、置信度高低的关键.作者提出的"动态网格"数据结构突破传统网格的静态切分的局限,采用"关键点控制网格节点"的方法,能任意改变自己的形状和密度以适应各种型面及精度的需要,使数据冗余趋近于零,很好地缓解了时空矛盾,提高了仿真置信度.成功应用于楔横轧模具加工过程的三维仿真.

| Abstract: | The contradiction between the speeds of graphic processing & showing and amount of data can or not be alleviated is the key of OpenGL simulation success or failure and reliability high or low.A dynamic mesh method which adopts "the key point control mesh node" is provided.It breaks the restrict of the traditional static split meshes,can change its own shape and density arbitrarily to adapt various type surface and precision,makes the data redundancy nearly null,which alleviate the time-space contradiction,and raised simulation reliability.The method is successfully applied to NC machining simulation of wedge roller. |
