vispy.geometry.isocurve module

vispy.geometry.isocurve.isocurve(data, level, connected=False, extend_to_edge=False)

Generate isocurve from 2D data using marching squares algorithm.

Parameters
datandarray

2D numpy array of scalar values

levelfloat

The level at which to generate an isosurface

connectedbool

If False, return a single long list of point pairs If True, return multiple long lists of connected point locations. (This is slower but better for drawing continuous lines)

extend_to_edgebool

If True, extend the curves to reach the exact edges of the data.
