Detailed Description

quantizes x,y,z coordinates of points

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.

If you wish to operate on a set of coordinates that has no cells, you must add a vtkPolyVertex cell with all of the points to the PolyData (or use a vtkVertexGlyphFilter) before using the vtkCleanPolyData filter.

Member Function Documentation

static vtkQuantizePolyDataPoints* vtkQuantizePolyDataPoints::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkCleanPolyData.

static int vtkQuantizePolyDataPoints::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.

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

(

double

)

[virtual]

Specify quantization grain size. Default is 0.25

virtual double vtkQuantizePolyDataPoints::GetQFactor
