Detailed Description

estimate volume, area, shape index of triangle mesh

vtkMassProperties estimates the volume, the surface area, and the normalized shape index of a triangle mesh. The algorithm implemented here is based on the discrete form of the divergence theorem. The general assumption here is that the model is of closed surface. For more details see the following reference (Alyassin A.M. et al, "Evaluation of new algorithms for the interactive measurement of surface area and volume", Med Phys 21(6) 1994.).

Warning:: Currently only triangles are processed. Use vtkTriangleFilter to convert any strips or polygons to triangles.

Member Function Documentation

vtkMassProperties* vtkMassProperties::New ( ) [static]

Constructs with initial values of zero.
Reimplemented from vtkAlgorithm.

virtual const char* vtkMassProperties::GetClassName ( ) [virtual]

Reimplemented from vtkProcessObject.

int vtkMassProperties::IsTypeOf ( const char * type ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkProcessObject.

virtual int vtkMassProperties::IsA ( const char * type ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkProcessObject.

vtkMassProperties* vtkMassProperties::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkProcessObject.

void vtkMassProperties::PrintSelf ( ostream & os,

vtkIndent indent

) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkProcessObject.
