pyvista_wasm.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. The shrink is computed in JavaScript at render time as a manual implementation because vtkShrinkPolyData is not registered with the vtkDeserializer in VTK.wasm’s rendering-mode binary.

Parameters:

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.

Returns:

A new mesh with shrunk cells.

Return type:

PolyData

Examples

Try it with JupyterLite!

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

Render the shrunk mesh:

>>> shrunk.plot()
