pyvista_js.PolyData.shrink

PolyData.shrink(shrink_factor: float = 0.8) → PolyData

Shrink the cells of a mesh towards their centroid.

This filter shrinks the individual cells of a mesh towards their centroids, producing visual separation between adjacent cells. It mirrors the PyVista shrink filter API.

注釈

The shrink is computed in JavaScript at render time by iterating over the cell array from the vtk.js source, moving each vertex toward its cell's centroid. vtk.js does not include vtkShrinkFilter, so this filter is implemented as a custom JavaScript pass.

パラメータ:

shrink_factor (float, optional) -- The factor to shrink each cell by, between 0 and 1. A value of 1.0 produces no change; lower values produce more shrinkage. Default is 0.8.

戻り値:

A new mesh with shrunk cells.

戻り値の型:

PolyData

サンプル

>>> import pyvista_js as pv
>>> sphere = pv.Sphere()
>>> shrunk = sphere.shrink(shrink_factor=0.8)
>>> isinstance(shrunk, pv.PolyData)
True

Render the shrunk mesh:

>>> shrunk.plot()
