Introduction

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