geomdl 5.4.0

Object-oriented B-Spline and NURBS evaluation library

Introduction

NURBS-Python (geomdl) is a pure Python, self-contained, object-oriented B-Spline and NURBS spline library.

Features

NURBS-Python (geomdl) provides convenient data structures and highly customizable API for rational and non-rational splines along with the efficient and extensible implementations of the following algorithms:

• Spline evaluation

• Derivative evaluation

• Knot insertion

• Knot removal

• Knot vector refinement

• Degree elevation

• Degree reduction

• Curve and surface fitting via interpolation and least squares approximation

NURBS-Python (geomdl) also provides customizable visualization and animation options via Matplotlib, Plotly and VTK libraries. Please refer to the documentation for more details.
