ParametricConicSpiral

ParametricConicSpiral(a=None, b=None, c=None, n=None, **kwargs)

Generate conic spiral surfaces that resemble sea-shells.

ParametricConicSpiral generates conic spiral surfaces. These can resemble sea shells, or may look like a torus “eating” its own tail.

Parameters
afloat, optional

The scale factor. Default is 0.2.

bfloat, optional

The A function coefficient. See the definition in Parametric surfaces referred to above. Default is 1.

cfloat, optional

The B function coefficient. See the definition in Parametric surfaces referred to above. Default is 0.1.

nfloat, optional

The C function coefficient. See the definition in Parametric surfaces referred to above. Default is 2.

**kwargsdict, optional

See surface_from_para() for additional keyword arguments.

Returns
pyvista.PolyData

ParametricConicSpiral surface.

Examples

Create a ParametricConicSpiral mesh.

>>> import pyvista
>>> mesh = pyvista.ParametricConicSpiral()
>>> mesh.plot(color='w', smooth_shading=True)
