vispy.geometry.curves module

vispy.geometry.curves.calc_sq_distance(x1, y1, x2, y2)
vispy.geometry.curves.curve3_bezier(p1, p2, p3)

The vertices returned by this function can be passed to a LineVisual or ArrowVisual.

Parameters
p1array

2D coordinates of the start point

p2array

2D coordinates of the first curve point

p3array

2D coordinates of the end point

Returns
coordslist

Vertices for the Bezier curve.
