Hi,
I am trying to draw lines that are always displayed on
top of Canvas3D. The lines should be visible no matter
what objects are in the SceneGraph.
Here is the code used to get the point from image
space(x, y) to 3D space (Point3d). In order to draw
lines that appear on top of Canvas3D, the points must
be further projected to the near clipping plane to be
able to achieve the objective.
Is there better or easier way to do this?
Thanks!

public Point3d getWorldCoordinate(Canvas3D canvas,
int x, int y ) {
Canvas3D canvas;
Transform3D ipToVworld = new Transform3D();
Point3d point = new Point3d();
//get the transformation
canvas.getImagePlateToVworld(ipToVworld);
canvas.getPixelLocationInImagePlate( x, y,
point );
//Get coordinate in world coordinate system.
ipToVworld.transform(point );
return point;
}
