ParametricConicSpiral(

b: float | None = None,

c: float | None = None,

n: float | None = None,

**kwargs,

) → PolyData

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, default: 0.2

The scale factor.

bfloat, default: 1

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

cfloat, default: 0.1

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

nfloat, default: 2

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

**kwargsdict, optional

See surface_from_para() for additional keyword arguments.

Returns:

pyvista.PolyData

ParametricConicSpiral surface.

Examples

Create a ParametricConicSpiral mesh.

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