Dear all:
please look carefully at this mail. i know there is a shape3D involved, but
i dont know which vintage it really occurs. the code in my
mouseClicked(MouseEvent e) shows hows i try to get the cone. the error that
it throws is shown below:
i create a cone and set all the Capabilities for it like ;
// create the cone and add it to the coneTG
Cone cone = new Cone(coneRadius, coneHeight,
Cone.ENABLE_GEOMETRY_PICKING|Cone.GENERATE_NORMALS|Cone.ENABLE_APPEARANCE_MO
DIFY, appearance);
cone.setCapability(Geometry.ALLOW_INTERSECT);
cone.setCapability(Shape3D.ALLOW_GEOMETRY_READ);
cone.setCapability(Shape3D.ALLOW_GEOMETRY_WRITE);
then when the mouse is clicked, i have this code below:
public void mouseClicked(MouseEvent e)
{
String stdev;
JSObject win = JSObject.getWindow(this);
pickCanvas.setShapeLocation(e);
PickResult pickResult = pickCanvas.pickClosest();
if (pickResult != null)
{
Cone pickedCone = (Cone) pickResult.getNode(PickResult.PRIMITIVE);
Switch thisSwitch = (Switch) pickResult.getNode(PickResult.SWITCH);
}
}
i keep getting this same error , but i am wondering what i am really
doing wrong, what should i do to avoid this error ?
the error is shown below:
thanks,
Isaac
