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 );

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.

virtual int vtkTerrainDataPointPlacer::ComputeWorldPosition	(	vtkRenderer *	ren,

		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.

	)			[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.
