Detailed Description

sort polydata along camera view direction

vtkPolyDataSilhouette extracts a subset of a polygonal mesh edges to generate an outline (silhouette) of the corresponding 3D object. In addition, this filter can also extracts sharp edges (aka feature angles). In order to use this filter you must specify the a point of view (origin) or a direction (vector). given this direction or origin, a silhouette is generated wherever the surface's normal is orthogonal to the view direction.

Warning:: when the active camera is used, almost everything is recomputed for each frame, keep this in mind when dealing with extremely large surface data sets.

Member Function Documentation

static vtkPolyDataSilhouette* vtkPolyDataSilhouette::New ( ) [static]

Instantiate object.

Reimplemented from vtkPolyDataAlgorithm.

static int vtkPolyDataSilhouette::IsTypeOf ( const char * name ) [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 vtkPolyDataAlgorithm.

virtual int vtkPolyDataSilhouette::IsA ( const char * name ) [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 vtkPolyDataAlgorithm.

static vtkPolyDataSilhouette* vtkPolyDataSilhouette::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkPolyDataSilhouette::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

vtkPolyDataSilhouette* vtkPolyDataSilhouette::NewInstance ( ) const

Reimplemented from vtkPolyDataAlgorithm.

void vtkPolyDataSilhouette::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 vtkPolyDataAlgorithm.

virtual void vtkPolyDataSilhouette::SetEnableFeatureAngle ( int ) [virtual]

Enables or Disables generation of silhouette edges along sharp edges

virtual int vtkPolyDataSilhouette::GetEnableFeatureAngle ( ) [virtual]

Enables or Disables generation of silhouette edges along sharp edges

virtual void vtkPolyDataSilhouette::SetFeatureAngle ( double ) [virtual]

Sets/Gets minimal angle for sharp edges detection. Default is 60

virtual double vtkPolyDataSilhouette::GetFeatureAngle ( ) [virtual]

Sets/Gets minimal angle for sharp edges detection. Default is 60

virtual void vtkPolyDataSilhouette::SetBorderEdges ( int ) [virtual]

Enables or Disables generation of border edges. Note: borders exist only in case of non closed surface

virtual int vtkPolyDataSilhouette::GetBorderEdges ( ) [virtual]

Enables or Disables generation of border edges. Note: borders exist only in case of non closed surface

virtual void vtkPolyDataSilhouette::BorderEdgesOn ( ) [virtual]

Enables or Disables generation of border edges. Note: borders exist only in case of non closed surface

virtual void vtkPolyDataSilhouette::BorderEdgesOff ( ) [virtual]

Enables or Disables generation of border edges. Note: borders exist only in case of non closed surface

virtual void vtkPolyDataSilhouette::SetPieceInvariant ( int ) [virtual]
