Detailed Description

sort poly data along camera view direction.

Date:
2001/10/11 13:37:24
Revision:
1.7
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]

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,
