Detailed Description

generate scalars along a specified direction

vtkElevationFilter is a filter to generate scalar values from a dataset. The scalar values lie within a user specified range, and are generated by computing a projection of each dataset point onto a line. The line can be oriented arbitrarily. A typical example is to generate scalars based on elevation or height above a plane.

Member Function Documentation

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

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

Reimplemented from vtkDataSetAlgorithm.

static int vtkElevationFilter::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 vtkDataSetAlgorithm.

virtual int vtkElevationFilter::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 vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

vtkElevationFilter* vtkElevationFilter::NewInstance ( ) const

Reimplemented from vtkDataSetAlgorithm.

void vtkElevationFilter::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 vtkDataSetAlgorithm.

virtual void vtkElevationFilter::SetLowPoint	(	double	,
		double	,
		double
	)		`[virtual]`

Define one end of the line (small scalar values). Default is (0,0,0).

virtual void vtkElevationFilter::SetLowPoint ( double [3] ) [virtual]

Define one end of the line (small scalar values). Default is (0,0,0).

virtual double* vtkElevationFilter::GetLowPoint ( ) [virtual]

Define one end of the line (small scalar values). Default is (0,0,0).

virtual void vtkElevationFilter::GetLowPoint ( double data[3] ) [virtual]

Define one end of the line (small scalar values). Default is (0,0,0).

virtual void vtkElevationFilter::SetHighPoint	(	double	,
		double	,
		double
	)		`[virtual]`

Define other end of the line (large scalar values). Default is (0,0,1).

virtual void vtkElevationFilter::SetHighPoint ( double [3] ) [virtual]

Define other end of the line (large scalar values). Default is (0,0,1).

virtual double* vtkElevationFilter::GetHighPoint ( ) [virtual]

Define other end of the line (large scalar values). Default is (0,0,1).

virtual void vtkElevationFilter::GetHighPoint ( double data[3] ) [virtual]

Define other end of the line (large scalar values). Default is (0,0,1).

virtual void vtkElevationFilter::SetScalarRange	(	double	,
		double
	)		`[virtual]`

Specify range to map scalars into. Default is [0, 1].

void vtkElevationFilter::SetScalarRange ( double [2] )

Specify range to map scalars into. Default is [0, 1].

virtual double* vtkElevationFilter::GetScalarRange ( ) [virtual]

Specify range to map scalars into. Default is [0, 1].

virtual void vtkElevationFilter::GetScalarRange ( double data[2] ) [virtual]

Specify range to map scalars into. Default is [0, 1].

int vtkElevationFilter::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)		`[protected, virtual]`

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.

Reimplemented from vtkDataSetAlgorithm.
