geomdl 4.0b5

NURBS curve and surface evaluation library in pure python

Description

NURBS-Python (geomdl) provides fully object-oriented Non-Uniform Rational B-Spline (NURBS) surface and curve data structures and extensible advanced computation algorithms in pure python. It allows users to directly visualize the computed curves and surfaces using various visualization libraries. Additionally, it comes with a surface generator.

Features

NURBS-Python consists of the following modules and components:

• Core library

• Exchange module

• Visualization component

• Shapes component

Core Library

The core library is responsible for data storage and evaluation. It is capable of handling B-Spline (NUBS) and NURBS curves and surfaces (single via geomdl.BSpline and geomdl.NURBS, multiple via geomdl.Multi modules). It provides an abstraction layer for easy extensibility (geomdl.Abstract), allows a variety of customizations and helper functionality, such as surface (geomdl.CPGen module) and uniform knot vector (geomdl.utilities.generate_knot_vector) generators.

Exchange Module

geomdl.exchange module can export control points and evaluated points of the Curve and Surface objects in common formats such as CSV, VTK, OBJ, OFF and STL.

Visualization Component

geomdl.visualization component contains customizable classes for plotting curves and surfaces directly.

Shapes Component

geomdl.shapes component provides an easy way to generate the most common curves and surfaces, such as circles and cylinders.
