WebTruncated Hierarchical B-Splines in Python. This repository contains a dimension-independent Python-implementation of truncated hierarchical B-splines, and methods … WebThe method uses a hierarchical quad-tree (2D) or octree (3D) structure to efficiently represent the surface details without a significant increase in the number of interior elements. Moreover, the geometry of the surface including normal information can be accurately incorporated in the model by using cubic (or higher-order) splines.
