Detailed Description

sort poly data along camera view direction.

Date:

2000/12/10 20:08:23

Revision:

1.3

Thanks:

Scott Hill for implementing this class

vtkDepthSortPolyData rearranges the order of cells so that certain rendering operations (e.g., transparency or Painter's algorithms) generate correct results. To use this filter you must specify the direction vector along which to sort the cells. You can do this by specifying a camera and/or prop to define a view direction; or explicitly set a view direction.

Warning:

The sort operation will not work well for long, thin primitives, or cells that intersect, overlap, or interpenetrate each other.

Member Function Documentation

vtkDepthSortPolyData* vtkDepthSortPolyData::New (    )  [static]

Instantiate object. Reimplemented from vtkPolyDataSource.

virtual const char* vtkDepthSortPolyData::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 vtkPolyDataToPolyDataFilter.

int vtkDepthSortPolyData::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 vtkPolyDataToPolyDataFilter.

virtual int vtkDepthSortPolyData::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 vtkPolyDataToPolyDataFilter.

vtkDepthSortPolyData* vtkDepthSortPolyData::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 vtkPolyDataToPolyDataFilter.

void vtkDepthSortPolyData::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.

virtual void vtkDepthSortPolyData::SetDirection (  int    )  [virtual]

Specify the sort method for the polygonal primitives.

virtual int vtkDepthSortPolyData::GetDirection (    )  [virtual]

void vtkDepthSortPolyData::SetDirectionToFrontToBack (    )  [inline]

Definition at line 87 of file vtkDepthSortPolyData.h.

void vtkDepthSortPolyData::SetDirectionToBackToFront (    )  [inline]

Definition at line 89 of file vtkDepthSortPolyData.h.

void vtkDepthSortPolyData::SetDirectionToSpecifiedVector (    )  [inline]

Definition at line 91 of file vtkDepthSortPolyData.h.

virtual void vtkDepthSortPolyData::SetCamera (  vtkCamera *    )  [virtual]

Specify a camera that is used to define a view direction along which the cells are sorted. This ivar only has effect if the direction is set to front-to-back or back-to-front, and a camera is specified.

virtual vtkCamera* vtkDepthSortPolyData::GetCamera (    )  [virtual]

void vtkDepthSortPolyData::SetProp3D (  vtkProp3D *    )

Specify a transformation matrix (via the vtkProp3D::GetMatrix() method) that is used to include the effects of transformation. This ivar only has effect if the direction is set to front-to-back or back-to-front, and a camera is specified. Specifying the vtkProp3D is optional.

vtkProp3D* vtkDepthSortPolyData::GetProp3D (    )

virtual void vtkDepthSortPolyData::SetVector (  double   , double   , double    )  [virtual]

Set/Get the sort direction. This ivar only has effect if the sort direction is set to SetDirectionToSpecifiedVector(). The sort occurs in the direction of the vector.

virtual void vtkDepthSortPolyData::SetVector (  double   [3] )  [virtual]

virtual double* vtkDepthSortPolyData::GetVector (    )  [virtual]

virtual void vtkDepthSortPolyData::GetVector (  double    data[3] )  [virtual]

virtual void vtkDepthSortPolyData::SetOrigin (  double   , double   , double    )  [virtual]

Set/Get the sort origin. This ivar only has effect if the sort direction is set to SetDirectionToSpecifiedVector(). The sort occurs in the direction of the vector, with this point specifying the origin.

virtual void vtkDepthSortPolyData::SetOrigin (  double   [3] )  [virtual]

virtual double* vtkDepthSortPolyData::GetOrigin (    )  [virtual]

virtual void vtkDepthSortPolyData::GetOrigin (  double    data[3] )  [virtual]

virtual void vtkDepthSortPolyData::SetSortScalars (  int    )  [virtual]

Set/Get a flag that controls the generation of scalar values corresponding to the sort order. If enabled, the output of this filter will include scalar values that range from 0 to (ncells-1), where 0 is closest to the sort direction.

virtual int vtkDepthSortPolyData::GetSortScalars (    )  [virtual]

virtual void vtkDepthSortPolyData::SortScalarsOn (    )  [virtual]

virtual void vtkDepthSortPolyData::SortScalarsOff (    )  [virtual]

unsigned long vtkDepthSortPolyData::GetMTime (    )  [virtual]

Return MTime also considering the dependent objects: the camera and/or the prop3D. Reimplemented from vtkObject.

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

Definition at line 137 of file vtkDepthSortPolyData.h.

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

Reimplemented from vtkSource.

void vtkDepthSortPolyData::ComputeProjectionVector (  double    vector[3], double    origin[3] )  [protected]
