Detailed Description

create surface from contours

vtkVoxelContoursToSurfaceFilter is a filter that takes contours and produces surfaces. There are some restrictions for the contours:

The contours are input as vtkPolyData, with the contours being polys in the vtkPolyData.
The contours lie on XY planes - each contour has a constant Z
The contours are ordered in the polys of the vtkPolyData such that all contours on the first (lowest) XY plane are first, then continuing in order of increasing Z value.
The X, Y and Z coordinates are all integer values.
The desired sampling of the contour data is 1x1x1 - Aspect can be used to control the aspect ratio in the output polygonal dataset.

This filter takes the contours and produces a structured points dataset of signed floating point number indicating distance from a contour. A contouring filter is then applied to generate 3D surfaces from a stack of 2D contour distance slices. This is done in a streaming fashion so as not to use to much memory.

Member Function Documentation

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

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

Reimplemented from vtkPolyDataAlgorithm.

virtual const char* vtkVoxelContoursToSurfaceFilter::GetClassName ( ) [virtual]

Reimplemented from vtkPolyDataAlgorithm.

static int vtkVoxelContoursToSurfaceFilter::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 vtkVoxelContoursToSurfaceFilter::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 vtkVoxelContoursToSurfaceFilter* vtkVoxelContoursToSurfaceFilter::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

void vtkVoxelContoursToSurfaceFilter::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.
