摘要： A method and system for computer aided design (CAD) is disclosed for designing geometric objects, wherein interpolation and/or blending between such objects is performed while deformation data is being input. Thus, a designer obtains immediate feedback to input modifications without separately entering a command(s) for performing such deformations. A novel N-sided surface generation technique is also disclosed herein to efficiently and accurately convert surfaces of high polynomial degree into a collection of lower degree surfaces. E.g., the N-sided surface generation technique disclosed herein subdivides parameter space objects (e.g., polygons) of seven or more sides into a collection of subpolygons, wherein each subpolygon has a reduced number of sides. More particularly, each subpolygon has 3 or 4 sides. The present disclosure is particularly useful for designing the shape of surfaces. Thus, the present disclosure is applicable to various design domains such as the design of, e.g., bottles, vehicles, and watercraft. Additionally, the present disclosure provides for efficient animation via repeatedly modifying surfaces of an animated object such as a representation of a face.
摘要翻译：公开了一种用于设计几何对象的计算机辅助设计（CAD）的方法和系统，其中在输入变形数据的同时执行这些对象之间的插值和/或混合。因此，设计者获得即时反馈以输入修改，而无需单独输入用于执行这种变形的命令。本文还公开了一种新颖的N侧表面生成技术，以有效且准确地将高次多项式的表面转换成较低表面的集合。例如，本文中公开的N侧表面生成技术将七个或更多个边的参数空间对象（例如，多边形）细分到子多边形的集合中，其中每个子多边形具有减少的边的数量。更具体地，每个子多边形具有3或4个边。本公开对于设计表面的形状特别有用。因此，本公开可应用于各种设计领域，例如瓶子，车辆和船舶的设计。另外，本公开通过重复地修改动画对象的表面（诸如面部表示）来提供有效的动画。

摘要： A method and system for computer aided design (CAD) is disclosed for designing geometric objects, wherein interpolation and/or blending between such objects is performed while deformation data is being input. Thus, a designer obtains immediate feedback to input modifications without separately entering a command (s) for performing such deformations. A novel N-sided surface generation technique is also disclosed herein to efficiently and accurately convert surfaces of high polynomial degree into a collection of lower degree surfaces. E.g., the N-sided surface generation technique disclosed herein subdivides parameter space objects (e.g., polygons) of seven or more sides into a collection of subpolygons, wherein each subpolygon has a reduced number of sides.
