# Create Connected Lines from Points
# ==================================

# Build a polyline from ordered points with `pyvista.MultipleLines()`.
import numpy as np
import pyvista as pv

# Create a winding polyline
# =========================

# The points are connected in the order they are given.
t = np.linspace(0, 1, 100)
points = np.column_stack(
    (
        6 * t - 3,
        np.sin(2 * np.pi * t),
        0.5 * np.cos(3 * np.pi * t),
    ),
)

line = pv.MultipleLines(points)
line['height'] = points[:, 1]
line

# Plot the line as a tube
# =======================

# Tubing the polyline gives it visible thickness in 3D.
pl = pv.Plotter()
pl.add_mesh(line.tube(radius=0.08), scalars='height', cmap='viridis')
pl.show()
