Standard_Real GetDeflection () const
 Returns absolute deflection used by this algorithm. This value is calculated on the basis of the shape's bounding box. Zero might be returned in case if the underlying OCCT shape is empty or invalid. Thus check the returned value before passing it to OCCT meshing algorithms! More...

Detailed Description

OCC implementation of IMesher interface.

Mesher produces shape data using implementation of IShapeData interface for VTK and then result can be retrieved from this implementation as a vtkPolyData:

Then the resulting vtkPolyData can be used for initialization of VTK pipeline.

◆ GetDeflection()

Standard_Real IVtkOCC_ShapeMesher::GetDeflection ( ) const

Returns absolute deflection used by this algorithm. This value is calculated on the basis of the shape's bounding box. Zero might be returned in case if the underlying OCCT shape is empty or invalid. Thus check the returned value before passing it to OCCT meshing algorithms!
