Detailed Description

estimate volume, area, shape index of triangle mesh.

Date:

2001/10/11 13:37:08

Revision:

1.19

Thanks:

Thanks to Abdalmajeid M. Alyassin who developed this class.

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 vtkProcessObject.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. 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 vtkTypeMacro 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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkProcessObject.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. 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.

double vtkMassProperties::GetVolume (    )  [inline]

Compute and return the volume. Definition at line 86 of file vtkMassProperties.h.

double vtkMassProperties::GetVolumeX (    )  [inline]

Compute and return the volume projected on to each axis aligned plane. Definition at line 91 of file vtkMassProperties.h.

double vtkMassProperties::GetVolumeY (    )  [inline]

Compute and return the volume projected on to each axis aligned plane. Definition at line 92 of file vtkMassProperties.h.

double vtkMassProperties::GetVolumeZ (    )  [inline]

Compute and return the volume projected on to each axis aligned plane. Definition at line 93 of file vtkMassProperties.h.

double vtkMassProperties::GetKx (    )  [inline]

Compute and return the weighting factors for the maximum unit normal component (MUNC). Definition at line 99 of file vtkMassProperties.h.

double vtkMassProperties::GetKy (    )  [inline]

Compute and return the weighting factors for the maximum unit normal component (MUNC). Definition at line 100 of file vtkMassProperties.h.

double vtkMassProperties::GetKz (    )  [inline]

Compute and return the weighting factors for the maximum unit normal component (MUNC). Definition at line 101 of file vtkMassProperties.h.

double vtkMassProperties::GetSurfaceArea (    )  [inline]

Compute and return the area. Definition at line 105 of file vtkMassProperties.h.

double vtkMassProperties::GetNormalizedShapeIndex (    )  [inline]

Compute and return the normalized shape index. This characterizes the deviation of the shape of an object from a sphere. A sphere's NSI is one. This number is always >= 1.0. Definition at line 111 of file vtkMassProperties.h.

void vtkMassProperties::Update (    )

void vtkMassProperties::SetInput (  vtkPolyData *    input )

vtkPolyData* vtkMassProperties::GetInput (    )

void vtkMassProperties::Execute (    )  [protected]
