PolyDataFilters.curvature

PolyDataFilters.curvature#

PolyDataFilters.curvature(curv_type='mean', progress_bar: bool = False)[source]#

Return the point-wise curvature of a mesh.

Parameters:
curv_typestr, default: “mean”

Curvature type. One of the following:

  • "mean"

  • "gaussian"

  • "maximum"

  • "minimum"

For "maximum" and "minimum", points where the discrete Gaussian and mean curvatures are inconsistent are assigned the mean curvature.

progress_barbool, default: False

Display a progress bar to indicate progress.

Returns:
numpy.ndarray

Array of curvature values.

Calculate the mean curvature of the hills example mesh and plot it.

>>> from pyvista import examples
>>> hills = examples.load_random_hills()
>>> curv = hills.curvature()
>>> hills.plot(scalars=curv)
