README.markdown

Gaining an intuitive understanding for b-splines is difficult without directly seeing the effects of different knot vectors and control point positions.

Curvey allows you to build b-spline curves by specifying the degree of the curve, control points, and the knot vector. This allows the user to see b-spline curves in its most general sense.

Setting Up

Download:

https://github.com/eshira/curvey/archives/master

If you like living on the edge, you can download the latest git snapshot:

$ git clone git://github.com/eshira/curvey.git

Curvey depends on Python an the Tkinter library, which is included in standard Python distributions. It has been tested on Python 2.6.

Using

To run the GUI version of Curvey:

$ python curvey.py --ui

You can also give Curvey an input file:

$ python curvey.py file
