Detailed Description

generate scalars from dot product of vectors and normals (e.g., show displacement plot).

Date:

2000/12/10 20:08:57

Revision:

1.25

vtkVectorDot is a filter to generate scalar values from a dataset. The scalar value at a point is created by computing the dot product between the normal and vector at that point. Combined with the appropriate color map, this can show nodal lines/mode shapes of vibration, or a displacement plot.

Member Function Documentation

virtual const char* vtkVectorDot::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 vtkDataSetToDataSetFilter.

int vtkVectorDot::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 vtkDataSetToDataSetFilter.

virtual int vtkVectorDot::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 vtkDataSetToDataSetFilter.

vtkVectorDot* vtkVectorDot::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 vtkDataSetToDataSetFilter.

void vtkVectorDot::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 vtkSource.

vtkVectorDot* vtkVectorDot::New (    )  [static]

Construct object with scalar range is (-1,1). Reimplemented from vtkDataSetSource.

virtual void vtkVectorDot::SetScalarRange (  float   , float    )  [virtual]

Specify range to map scalars into.

void vtkVectorDot::SetScalarRange (  float   [2] )

virtual float* vtkVectorDot::GetScalarRange (    )  [virtual]

Get the range that scalars map into.

virtual void vtkVectorDot::GetScalarRange (  float    data[2] )  [virtual]

void vtkVectorDot::operator= (  const vtkVectorDot &    )  [inline, protected]

Definition at line 80 of file vtkVectorDot.h.

void vtkVectorDot::Execute (    )  [protected, virtual]

Reimplemented from vtkSource.
