论文摘要
我们介绍了具有准确边界控制的修剪型NURBS表面，简要称为ABC-Surfaces，以解决构建水密或光滑的臭名昭著的问题（$ g^1 $和$ g^2）$多斑点表面在标准CAD/CAM系统功能范围内，以及相关文件交换格式。我们的构造基于基本表面的适当混合物，该基础表面可以追踪预期的全局形状，以及一系列重新训练的丝带，这些丝带占据了边界附近的形状。
We introduce trimmed NURBS surfaces with accurate boundary control, briefly called ABC-surfaces, as a solution to the notorious problem of constructing watertight or smooth ($G^1$ and $G^2)$ multi-patch surfaces within the function range of standard CAD/CAM systems and the associated file exchange formats. Our construction is based on the appropriate blend of a base surface, which traces out the intended global shape, and a series of reparametrized ribbons, which dominate the shape near the boundary.
