Detailed Description

Place points on terrain data.

vtkTerrainDataPointPlacer dictates the placement of points on height field data. The class takes as input the list of props that represent the terrain in a rendered scene. A height offset can be specified to dicatate the placement of points at a certain height above the surface.

Usage:: A typical usage of this class is as follows:
pointPlacer->AddProp(demActor); // the actor(s) containing the terrain.

rep->SetPointPlacer(pointPlacer);

pointPlacer->SetHeightOffset( 100 );

Member Function Documentation

◆ New()

static vtkTerrainDataPointPlacer* vtkTerrainDataPointPlacer::New ( )

static

Instantiate this class.

◆ IsTypeOf()

static int vtkTerrainDataPointPlacer::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkTerrainDataPointPlacer::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 vtkPointPlacer.

◆ SafeDownCast()

static vtkTerrainDataPointPlacer* vtkTerrainDataPointPlacer::SafeDownCast ( vtkObjectBase * o )

vtkTerrainDataPointPlacer* vtkTerrainDataPointPlacer::NewInstance ( ) const

◆ PrintSelf()

void vtkTerrainDataPointPlacer::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 vtkPointPlacer.

virtual void vtkTerrainDataPointPlacer::RemoveAllProps ( )

virtual

◆ SetHeightOffset()

virtual void vtkTerrainDataPointPlacer::SetHeightOffset ( double )

virtual

This is the height above (or below) the terrain that the dictated point should be placed. Positive values indicate distances above the terrain; negative values indicate distances below the terrain. The default is 0.0.

◆ GetHeightOffset()

virtual double vtkTerrainDataPointPlacer::GetHeightOffset ( )

◆ ComputeWorldPosition() [1/2]

virtual int vtkTerrainDataPointPlacer::ComputeWorldPosition	(	vtkRenderer *	ren,
		double	displayPos[2],
		double	worldPos[3],
		double	worldOrient[9]
	)

virtual

Given a renderer and a display position in pixel coordinates, compute the world position and orientation where this point will be placed. This method is typically used by the representation to place the point initially. For the Terrain point placer this computes world points that lie at the specified height above the terrain.

Reimplemented from vtkPointPlacer.

◆ ComputeWorldPosition() [2/2]

virtual int vtkTerrainDataPointPlacer::ComputeWorldPosition	(	vtkRenderer *	ren,
		double	displayPos[2],
		double	refWorldPos[3],
		double	worldPos[3],
		double	worldOrient[9]
	)

virtual

Given a renderer, a display position, and a reference world position, compute the new world position and orientation of this point. This method is typically used by the representation to move the point.

Reimplemented from vtkPointPlacer.

◆ ValidateWorldPosition() [1/2]

virtual int vtkTerrainDataPointPlacer::ValidateWorldPosition ( double worldPos[3] )

virtual

Given a world position check the validity of this position according to the constraints of the placer

Reimplemented from vtkPointPlacer.

◆ ValidateDisplayPosition()

virtual int vtkTerrainDataPointPlacer::ValidateDisplayPosition	(	vtkRenderer *	,
		double	displayPos[2]
	)

virtual

Given a display position, check the validity of this position.

Reimplemented from vtkPointPlacer.

◆ ValidateWorldPosition() [2/2]

virtual int vtkTerrainDataPointPlacer::ValidateWorldPosition	(	double	worldPos[3],
		double	worldOrient[9]
	)

virtual

Given a world position and a world orientation, validate it according to the constraints of the placer.

Reimplemented from vtkPointPlacer.

◆ GetPropPicker()

virtual vtkPropPicker* vtkTerrainDataPointPlacer::GetPropPicker ( )

virtual

Get the Prop picker.
