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.
