Detailed Description

convert an arbitrary dataset to a voxel representation

vtkVoxelModeller is a filter that converts an arbitrary data set to a structured point (i.e., voxel) representation. It is very similar to vtkImplicitModeller, except that it doesn't record distance; instead it records occupancy. By default it supports a compact output of 0/1 VTK_BIT. Other vtk scalar types can be specified. The Foreground and Background values of the output can also be specified. NOTE: Not all vtk filters/readers/writers support the VTK_BIT scalar type. You may want to use VTK_CHAR as an alternative.

Constructor & Destructor Documentation

vtkVoxelModeller::vtkVoxelModeller ( ) [protected]

Set the Foreground/Background values of the output. The Foreground value is set when a voxel is occupied. The Background value is set when a voxel is not occupied. The default ForegroundValue is 1. The default BackgroundValue is 0.

vtkVoxelModeller::~vtkVoxelModeller ( ) [inline, protected]

Set the Foreground/Background values of the output. The Foreground value is set when a voxel is occupied. The Background value is set when a voxel is not occupied. The default ForegroundValue is 1. The default BackgroundValue is 0.

Member Function Documentation

static int vtkVoxelModeller::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 vtkImageAlgorithm.

virtual int vtkVoxelModeller::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 vtkImageAlgorithm.

static vtkVoxelModeller* vtkVoxelModeller::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkImageAlgorithm.

virtual vtkObjectBase* vtkVoxelModeller::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkImageAlgorithm.

vtkVoxelModeller* vtkVoxelModeller::NewInstance ( ) const

Reimplemented from vtkImageAlgorithm.

void vtkVoxelModeller::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 vtkImageAlgorithm.

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

Construct an instance of vtkVoxelModeller with its sample dimensions set to (50,50,50), and so that the model bounds are automatically computed from its input. The maximum distance is set to examine the whole grid. This could be made much faster, and probably will be in the future.

Reimplemented from vtkAlgorithm.

double vtkVoxelModeller::ComputeModelBounds	(	double	origin[3],
		double	ar[3]
	)

Compute the ModelBounds based on the input geometry.

void vtkVoxelModeller::SetSampleDimensions	(	int	i,
		int	j,
		int	k
	)

Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50)

void vtkVoxelModeller::SetSampleDimensions ( int dim[3] )

Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50)

virtual int* vtkVoxelModeller::GetSampleDimensions ( ) [virtual]

Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50)

virtual void vtkVoxelModeller::GetSampleDimensions ( int data[3] ) [virtual]

Set the i-j-k dimensions on which to sample the distance function. Default is (50, 50, 50)

virtual void vtkVoxelModeller::SetMaximumDistance ( double ) [virtual]

Specify distance away from surface of input geometry to sample. Smaller values make large increases in performance. Default is 1.0.

virtual double vtkVoxelModeller::GetMaximumDistance ( ) [virtual]

Specify distance away from surface of input geometry to sample. Smaller values make large increases in performance. Default is 1.0.

void vtkVoxelModeller::SetModelBounds ( double bounds[6] )

		double	xmax,
		double	ymin,
		double	ymax,
		double	zmin,
