Class RMTrackballControl

  • All Implemented Interfaces:
    java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, javax.swing.Scrollable

    public class RMTrackballControl
    extends RMViewer
    This class implements the trackball widget. It is an optional replacement for the Scene3DControl.

    Trackball inherits the RMScene3D's behavior, which is that mouse motion in the x direction changes the pitch, and mouse motion in the y direction changes the yaw. The controll adds rotation about the z axis (roll) by clicking on a ring outside the trackball.

    Note that this particular behavior quickly goes wrong, since Rotate(y,x,z) * Rotate(dy,dx,dz) != Rotate (y+dy, x+dx, z+dz)

    To make the behavior more reasonable, we could try any of : 1. Make Scene3D keep a matrix,instead of the euler angles and just keep rotating that by dx,dy,dz 2. Get the matrix, rotate by dx,dy,dz, decompose into new euler angles and set those 3. Use quaternions (gasp)
