All Implemented Interfaces:

java.lang.Cloneable

public class PointManipulationRendererJ3D
extends DirectManipulationRendererJ3D

PointManipulationRendererJ3D is the VisAD class for direct manipulation of single points

Field Summary

Fields inherited from class visad.DataRenderer

enabled, pickCrawlToCursor

Constructor Summary

PointManipulationRendererJ3D(RealType xarg, RealType yarg)
this DirectManipulationRenderer is quite different - it does not render its data, but only place values into its DataReference on right mouse button press; it uses xarg and yarg to determine spatial ScalarMaps

PointManipulationRendererJ3D(RealType xarg, RealType yarg, int mmm, int mmv)
xarg and yarg determine spatial ScalarMaps; mmm and mmv determine whehter SHIFT or CTRL keys are required - this is needed since this is a greedy DirectManipulationRenderer that will grab any right mouse click (that intersects its 2-D sub-manifold)

Method Summary

void	addPoint(float[] x)
float	checkClose(double[] origin, double[] direction) check if ray intersects sub-manifold
void	checkDirect() set isDirectManipulation = true if this DataRenderer supports direct manipulation for its linked Data
java.lang.Object	clone()
javax.media.j3d.BranchGroup	doTransform() don't render - just return BranchGroup for scene graph to render rectangle into
void	drag_direct(VisADRay ray, boolean first, int mouseModifiers)
CoordinateSystem	getDisplayCoordinateSystem()
java.lang.String	getWhyNotDirect()
static void	main(java.lang.String[] args) test PointManipulationRendererJ3D
void	setSpatialValues(float[][] spatial_values) set spatialValues from ShadowType.doTransform
void	stop_direct() discontinue dragging this DataRenderer; this method is not a general disable
