pyvista.Superquadric

Superquadric(center=(0.0, 0.0, 0.0), scale=(1.0, 1.0, 1.0), size=0.5, theta_roundness=1.0, phi_roundness=1.0, theta_resolution=16, phi_resolution=16, toroidal=False, thickness=0.3333333333333333)

Create a superquadric.

Parameters:

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

Center of the superquadric in [x, y, z].

scalesequence[float], default: (1.0, 1.0, 1.0)

Scale factors of the superquadric in [x, y, z].

sizefloat, default: 0.5

Superquadric isotropic size.

theta_roundnessfloat, default: 1.0

Superquadric east/west roundness. Values range from 0 (rectangular) to 1 (circular) to higher orders.

phi_roundnessfloat, default: 1.0

Superquadric north/south roundness. Values range from 0 (rectangular) to 1 (circular) to higher orders.

theta_resolutionint, default: 16

Number of points in the longitude direction. Values are rounded to nearest multiple of 4.

phi_resolutionint, default: 16

Number of points in the latitude direction. Values are rounded to nearest multiple of 8.

toroidalbool, default: False

Whether or not the superquadric is toroidal (True) or ellipsoidal (False).

thicknessfloat, default: 0.3333333333

Superquadric ring thickness. Only applies if toroidal is set to True.

Returns:

pyvista.PolyData

Superquadric mesh.
