NURBS-Python 3.4.1

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

NURBS-Python consists of the following modules and components:

• Core library

• Multi module

• Exchange module

• Visualization component

• Shapes component

Core Library

The core library 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 altering 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

Starting from version 3.2, NURBS-Python provides abstract Curve and Surface base classes in geomdl.Abstract module.

Multi Module

NURBS-Python provides container-like classes for working with multiple curves and surfaces in geomdl.Multi module. Please see the documentation for details.

Exchange Module

NURBS-Python can export Surface types in OBJ and STL format using geomdl.exchange module. This module contains 2 major functions:

• save_obj for saving surfaces as .obj files

• save_stl for saving surfaces as .stl files in ascii or binary format (default is binary)

Visualization Component

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

Shapes Component

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