NURBS-Python v3.2.0

• The core library now utilizes Abstract and Multi modules
• Curve classes now have split() method for curve splitting at the given parameter and decompose() method for Bézier decomposition
• Shapes module upgrades

• Added decompose method to curve classes for applying Bézier decomposition
• Added add_list method to Multi module

NURBS-Python v3.1.3

A new version of NURBS-Python is released on GitHub and PyPI. To install: pip install NURBS-Python

Changes

• Minor bug fixes
• Added translate() function to curve classes

NURBS-Python v3.1.2

A new version of NURBS-Python is released on GitHub and PyPI. To install: pip install NURBS-Python

Bug fixes

• Fix a control points copy error in insert_knot() methods
• Increased stability of generate_knot_vector() function
• Some other minor fixes in exchange module

Updated features

• save_obj can save single or multiple surfaces to a single .obj file
• Curve and Curve2D classes have a new method, split(). This method splits the curve and returns 2 new instances as the split pieces of the initial curve. It doesn't modify the initial curve.

New features for preview

• Multi module is designed to operate on multiple curves and surfaces. Currently, it can only do multi curve and multi surface visualization (in 2D and 3D) on the same window. Documentation will come soon.
• Abstract module provides a base for further development of the NURBS algorithms. It will become the base class for B-Spline and NURBS curves and surfaces represented in NURBS-Python. Unfortunately, the module is still WIP and it could remain like that for a while.

Future work

• Extend split() for surfaces
• Add Bézier decomposition for curves and surfaces

• Performance improvements
• Documentation updates
