Polyhedral splines

Polyhedral splines

Polyhedral Splines is an add-on that converts quad-dominant meshes into B-spline patches. It enables artists to edit spline surfaces in real-time, leveraging Blender’s existing polyhedral modeling capabilities.

Key Features:

  • Smooth Surfaces Without Subdividing Mesh: Unlike Blender’s default subdivision and smooth operator, this add-on maintains a manageable vertex count while achieving smooth surfaces.
  • Computation of Moments: Allows for the easy and exact computation of various metrics such as volume, center of mass, and axes of inertia.
  • Preservation of Polyhedral Character: The add-on retains the polyhedral nature of the input mesh, using low-degree splines that generalize bi-2 and bi-quadratic splines.
  • Mesh Inspection: Features a mesh inspection tool to highlight connectivity not supported by the algorithm.
  • B-spline Patch Generation: Facilitates the generation of multiple patch objects from a mesh, useful for larger meshes.
  • Interactive Modeling: Users can interactively edit the shape by manipulating control points.
  • Visibility Controls: Includes options to show or hide the boundary of patches and faces of the control polygon.
  • Patch Coloring: Allows setting different colors for patches generated by different configurations.
