Detailed Description

Intersect a mesh with an implicit surface.

This filter accepts a vtkm::ImplicitFunction that defines the surface to slice on. A vtkm::Plane is a common function to use that cuts the mesh along a plane.

Member Function Documentation

◆ DoExecute()

vtkm::cont::DataSet vtkm::filter::contour::Slice::DoExecute ( const vtkm::cont::DataSet & input )

overrideprivatevirtual

Reimplemented from vtkm::filter::contour::Contour.

◆ GetImplicitFunction()

const vtkm::ImplicitFunctionGeneral& vtkm::filter::contour::Slice::GetImplicitFunction ( ) const

inline

Get the implicit function that us used to perform the slicing.

◆ SetImplicitFunction()

void vtkm::filter::contour::Slice::SetImplicitFunction ( const vtkm::ImplicitFunctionGeneral & func )

inline

Set the implicit function that is used to perform the slicing.

Only a limited number of implicit functions are supported. See vtkm::ImplicitFunctionGeneral for information on which ones.
