High-Quality Shape Design and Surface Representation

表面形状和质量对新产品设计和工业竞争力有着明显的影响。 这项研究解决了光滑连接多个表面件没有形状缺陷的根本挑战。 新方法将形状设计与曲面表示分离，在提供工业设计所需的标准表示的同时，给设计者更多的自由度，形状由曲面片段局部定义，称为引导曲面。 导向面只需要服从很少的约束。 在第二步中，每个引导表面的导数射流被采样并转换为标准表示中的曲率连续参数表面。 该研究的特点类的引导表面，设计自动引导表面的建设和形式化的战略，并分析在实际实施中的射流采样策略的属性。

Surface shape and quality have a visible impact on new product design and industrial competitiveness. This research addresses the fundamental challenge of smoothly joining multiple surface pieces without shape defects. The new approach separates shape design from surface representation and thereby gives more freedom to the designer while still delivering a standard representation required by industrial design cycles.In the new approach, shape is locally defined by surface fragments, called guide surfaces. Guide surfaces need only obey few constraints. In a second step, the derivative jets of each guide surface are sampled and converted to curvature continuous parametric surfaces in standard representation. The research characterizes classes of guide surfaces, devises strategies for automatic guide surface construction and formalizes and analyzes the properties of jet sampling strategies in practical implementations.
