NURBS-Python 3.2.1

NURBS 2D/3D curve and surface evaluation library in native Python

Description

NURBS-Python provides Non-Uniform Rational B-Spline (NURBS) surface and 2D/3D curve data structures and computation algorithms in native Python. The library is fully object-oriented and does not depend on any external libraries.

Features

The package contains 4 modules:

• geomdl.BSpline contains Non-Uniform B-Spline (NUBS) evaluation and storage functionality

• geomdl.NURBS contains Non-Uniform Rational B-Spline (NURBS) evaluation and storage functionality

• geomdl.CPGen contains simple control points grid generation algorithms

• geomdl.utilities contains helper functions for generating and manipulating knot vectors and control points

geomdl.BSpline and geomdl.NURBS modules contain 3 classes for geometric evaluation:

• Curve for evaluating 3D curves

• Curve2D for evaluating 2D curves

• Surface for evaluating surfaces

geomdl.CPGen module contains 2 classes for grid generation:

• Grid for generating inputs for geomdl.BSpline.Surface class

• GridWeighted for generating inputs for geomdl.NURBS.Surface class

Examples

Please see the Examples repository for more details and example scripts on how to use NURBS-Python.

Visualization

NURBS-Python comes with an experimental visualization module, geomdl.visualization, for plotting the generated 2D/3D curves and surfaces directly.

Shapes

Starting from NURBS-Python v3.1, a new experimental module geomdl.shapes is shipped with the package. The aim of this module is providing an easy way to generate the most common curves and surfaces, such as circles and cylinders.
