pyvista.CylinderStructured

CylinderStructured(radius=0.5, height=1.0, center=(0.0, 0.0, 0.0), direction=(1.0, 0.0, 0.0), theta_resolution=32, z_resolution=10)

Create a cylinder mesh as a pyvista.StructuredGrid.

The end caps are left open. This can create a surface mesh if a single value for the radius is given or a 3D mesh if multiple radii are given as a list/array in the radius argument.

Parameters:

radiusfloat | sequence[float], default: 0.5

Radius of the cylinder. If a sequence, then describes the radial coordinates of the cells as a range of values as specified by the radius.

heightfloat, default: 1.0

Height of the cylinder along its Z-axis.

centersequence[float], default: (0.0, 0.0, 0.0)

Location of the centroid in [x, y, z].

directionsequence[float], default: (1.0, 0.0, 0.0)

Direction cylinder Z-axis in [x, y, z].

theta_resolutionint, default: 32

Number of points on the circular face of the cylinder. Ignored if radius is an iterable.

z_resolutionint, default: 10

Number of points along the height (Z-axis) of the cylinder.

Returns:

pyvista.StructuredGrid

Structured cylinder.

Notes

Changed in version 0.38.0: Prior to version 0.38, this method had incorrect results, producing inconsistent number of points on the circular face of the cylinder.

Examples

Default structured cylinder

>>> import pyvista as pv
>>> mesh = pv.CylinderStructured()
>>> mesh.plot(show_edges=True)
