Hello,
I have used the ObjLoad class (application) distributed with
java3d 1.1 to display a surface. What I would like to do is to
allow the user to click on the surface and have the coordinates
of the nearest vertex be printend out to stdio. So I tried
the following code:
class SurfaceMouseListener extends MouseAdapter {
public void mouseClicked(MouseEvent evt) {
System.out.println("Mouse Clicked: " + evt);
Point3d p = new Point3d();
Transform3D xform = new Transform3D();
c.getPixelLocationInImagePlate(evt.getX(), evt.getY(), p);
System.out.println("The (x, y) mouse coordinates: " + p);
c.getImagePlateToVworld(xform);
System.out.println(xform);
xform.transform(p);
System.out.println("The point3d is: " + p);
}
}
and I used the above class to listen to the mouse. Keeping in mind
that the surface is made of vertices (that are point3D) of the form:
v 125.759003 147.942993 87.498398
v 29.879999 141.669998 87.336304
v 77.745796 219.962006 80.463097
v 82.861603 59.720299 95.204803
v 81.098099 142.345993 141.294998
v 78.962502 142.395996 43.585400
So from the above code I expect the value printed for "P"
to be one of the surface vertices. I also expect the value
of "p" to change as I rotate/translate the surface. This is
not the case though and I am wondering what I am doing wrong.
Please let me know if the above code is suppose to do what
I am wanting to do. If you have a sample code using
PickRay+PickClosest I would truly appreciate it if you
could send it to me.
Thanks,
- Abed
