Abstract: One embodiment of the present application sets forth a computer-implemented method for generating a three-dimensional (3D) surface model. The method includes joining a first 3D object having a first closed surface mesh and a second 3D object having a second closed surface mesh to produce an irregular surface mesh. The method further includes computing a first intersection contour for the irregular surface mesh. The method further includes removing at least one portion of the irregular surface mesh proximate to the first intersection contour to produce a first boundary. The method further includes growing the first boundary towards at least one other boundary. The method further includes connecting the first boundary to the at least one other boundary to produce a portion of a non-manifold surface mesh that comprises at least a portion of the 3D surface model.

Abstract: A single model engine for receiving and processing a 3D surface model representing the surface of a 3D object, the 3D surface model comprising at least two distinct surface regions associated with at least two different materials. The single model engine automatically produce a set of interior sheets inside the 3D surface model, the set of interior sheets defining interior boundaries and interior volumes of the different materials for the 3D object. The single model engine combines the 3D surface model with the set of interior sheets to produce a single unified model that represents the surface and interior volumes of the 3D object that comprise a single solid object having at least two different materials. At print time, the single model engine performs an export technique to produce an exportable form of the single unified model that can be received and printed by a 3D printer.

Abstract translation: 用于接收和处理表示3D对象的表面的3D表面模型的单一模型引擎，所述3D表面模型包括与至少两种不同材料相关联的至少两个不同的表面区域。 单一模型引擎在3D表面模型内自动生成一组内部纸张，该组内部纸张定义了3D对象不同材质的内部边界和内部体积。 单一模型引擎将3D表面模型与内部纸张组合以产生单个统一模型，其表示构成具有至少两种不同材料的单一固体物体的3D对象的表面和内部体积。 在打印时，单一模型引擎执行导出技术，以生成可由3D打印机接收和打印的单一统一模型的可导出形式。
