Points to Tube¶
This example will demonstrate how to to build a tube from a set of points in vtkPolyData.
Takes points from a vtkPolyData object and constructs a line of those points then builds a polygonal tube around that line with some specified radius and number of sides.
# sphinx_gallery_thumbnail_number = 2 import pyvista import numpy as np from PVGeo.filters import PointsToTube
def path(y): """Equation: x = a(y-h)^2 + k""" a = - 110.0 / 160.0**2 x = a*y**2 + 110.0 return x, y x, y = path(np.arange(0.0, 200.0, 25.0)) zo = np.linspace(9.0, 11.0, num=len(y)) points = pyvista.PolyData(np.c_[x,y,zo]) points.plot(point_size=10)
# Use the filter: here is vtkPolyData containing the tube tube = PointsToTube(nearestNbr=True).apply(points) tube.plot(color=True)
