Detailed Description

quantizes x,y,z coordinates of points.

Thanks:

Thanks to John Biddiscombe of the Rutherford Appleton Laboratory who developed and contributed this class.

vtkQuantizePolyDataPoints is a subclass of vtkCleanPolyData and inherits the functionality of vtkCleanPolyData with the addition that it quantizes the point coordinates before inserting into the point list. The user should set QFactor to a positive value (0.25 by default) and all {x,y,z} coordinates will be quantized to that grain size.

A tolerance of zero is expected, though positive values may be used, the quantization will take place before the tolerance is applied.

Warning:

Merging points can alter topology, including introducing non-manifold forms. Handling of degenerate cells is controlled by switches in vtkCleanPolyData.

Member Function Documentation

vtkQuantizePolyDataPoints* vtkQuantizePolyDataPoints::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkCleanPolyData.

virtual const char* vtkQuantizePolyDataPoints::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 vtkCleanPolyData.

int vtkQuantizePolyDataPoints::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 vtkCleanPolyData.

virtual int vtkQuantizePolyDataPoints::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 vtkCleanPolyData.

vtkQuantizePolyDataPoints* vtkQuantizePolyDataPoints::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 vtkCleanPolyData.

void vtkQuantizePolyDataPoints::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 vtkCleanPolyData.

virtual void vtkQuantizePolyDataPoints::SetQFactor (  float    )  [virtual]

Specify quantization grain size

virtual float vtkQuantizePolyDataPoints::GetQFactor (    )  [virtual]

Specify quantization grain size

virtual void vtkQuantizePolyDataPoints::OperateOnPoint (  float    in[3], float    out[3] )  [virtual]

Perform quantization on a point Reimplemented from vtkCleanPolyData.

virtual void vtkQuantizePolyDataPoints::OperateOnBounds (  float    in[6], float    out[6] )  [virtual]

Perform quantization on bounds Reimplemented from vtkCleanPolyData.
