Use streamtubes to visualize polylines.

Parameters:

lineslist: list of N curves represented as 2D ndarrays
colorsarray (N, 3), list of arrays, tuple (3,), array (K,): If None or False, a standard orientation colormap is used for every line. If one tuple of color is used. Then all streamlines will have the same colour. If an array (N, 3) is given, where N is equal to the number of lines. Then every line is coloured with a different RGB color. If a list of RGB arrays is given then every point of every line takes a different color. If an array (K, 3) is given, where K is the number of points of all lines then every point is colored with a different RGB color. If an array (K,) is given, where K is the number of points of all lines then these are considered as the values to be used by the colormap. If an array (L,) is given, where L is the number of streamlines then these are considered as the values to be used by the colormap per streamline.

Notes

Streamtubes can be heavy on GPU when loading many streamlines and therefore, you may experience slow rendering time depending on system GPU. A solution to this problem is to reduce the number of points in each streamline. In Dipy we provide an algorithm that will reduce the number of points on the straighter parts of the streamline but keep more points on the curvier parts. This can be used in the following way:

from dipy.tracking.distances import approx_polygon_track
lines = [approx_polygon_track(line, 0.2) for line in lines]

Alternatively we suggest using the line actor which is much more efficient.

Examples

>>> import numpy as np
>>> from fury import actor, window
>>> scene = window.Scene()
>>> lines = [np.random.rand(10, 3), np.random.rand(20, 3)]
>>> colors = np.random.rand(2, 3)
>>> c = actor.streamtube(lines, colors=colors)
>>> scene.add(c)
>>> #window.show(scene)

Create an actor for one or more lines.

Parameters:

lineslist of arrays
colorsarray (N, 3), list of arrays, tuple (3,), array (K,): If None or False, a standard orientation colormap is used for every line. If one tuple of color is used. Then all streamlines will have the same colour. If an array (N, 3) is given, where N is equal to the number of lines. Then every line is coloured with a different RGB color. If a list of RGB arrays is given then every point of every line takes a different color. If an array (K, 3) is given, where K is the number of points of all lines then every point is colored with a different RGB color. If an array (K,) is given, where K is the number of points of all lines then these are considered as the values to be used by the colormap. If an array (L,) is given, where L is the number of streamlines then these are considered as the values to be used by the colormap per streamline. If an array (X, Y, Z) or (X, Y, Z, 3) is given then the values for the colormap are interpolated automatically using trilinear interpolation.
