Introduction

NURBS-Python (geomdl) is an object-oriented B-Spline and NURBS surface and curve library for Python with implementations of advanced computation algorithms in an extensible way. It comes with on-the-fly shape visualization options, knot vector and surface grid generators, and more.

NURBS-Python (geomdl) is a pure Python library, therefore there are no external C/C++ or FORTRAN dependencies or any compilation steps during installation. It is tested with Python v2.7.x, Python v3.3.x and later versions. The Python 2 and 3 compatibility library six will be automatically installed during NURBS-Python setup.

Please see the Examples Repository for details on library usage and integration scenarios.

Note: This package replaces the old NURBS-Python with new and improved features. Please see the Installation documentation page on removing the old package and installing the new package.

Features

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.

The Core Library module of NURBS-Python is self-contained. It implements all the necessary maths and linear algebra operations without needing any other external modules.

Exchange Module

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

Visualization Component

geomdl.visualization component contains extensible and customizable classes for plotting curves and surfaces on-the-fly. The users have options to use Matplotlib and/or Plotly visualization libraries. These libraries are not automatically installed during NURBS-Python setup and they are left for users’ discretion.

More Features

NURBS-Python (geomdl) is more than a simple NURBS library. It has many features and they are customizable for your needs. Please see the Modules documentation page for the list of modules and features.
