    • Various embodiments of a system and methods for generating a manifold surface of an object from a set of 3D curves which define the shape of the object are described. The set of 3D curves may be directly tessellated in the 3D domain to form a manifold surface with boundary. The tessellation may be a Delaunay tetrahedralization which represents the set of 3D curves. The surface of the tetrahedralization may contain a set of possible manifold surface solutions. A dual complex form of the tetrahedralization may be generated to reduce the number of possible manifold surface solutions. Surface patches may be generated from the dual complex form, dependent on a set of metrics that may further reduce the number of possible manifold surface solutions. Compatible surface patches may be combined to form a set of possible manifold surface solutions which may be displayed to a user.
    • 描述了用于从限定对象的形状的一组3D曲线生成对象的歧管表面的系统和方法的各种实施例。 3D曲线的集合可以在3D域中直接镶嵌形成具有边界的歧管表面。 曲面细分可能是Delaunay四面体化,它代表一组3D曲线。 四面体化的表面可能包含一组可能的歧管表面溶液。 可以产生双重复合形式的四面体化以减少可能的歧管表面溶液的数量。 表面斑块可以从双重复杂形式产生,取决于一组度量,其可以进一步减少可能的歧管表面溶液的数量。 可以组合兼容的表面贴片以形成可以向用户显示的一组可能的歧管表面解决方案。
