Polyhedral Splines is an add-on for Blender that allows artists to convert quad-dominant meshes into B-spline patches. This allows for real-time editing of spline surfaces using Blender’s existing modeling capabilities. The add-on offers smooth surfaces without the need for subdividing the mesh, which can be computationally and storage-intensive. It also enables easy computation of moments like volume, center of mass, and axes of inertia. Polyhedral splines preserve the polyhedral character of the input, extending the capabilities of bi-2 and bi-quadratic splines. The add-on includes features for mesh inspection, B-spline patch generation, and interactive modeling. There are implemented algorithms and configurable options for the user.
