need tutorial/help with 3D applet
I am looking for a tutorial on creating an applet in 3D. I copied this one
It is a 3D vector field. To get an idea of what I would like to demonstrate, set the following properties:
This gives the picture of a cylindrical 'tornado' sitting on the xy plane with its vertical axis perpendicular to the xy plane.
I would like to be able to deform the xy plane and maintain the constraint that the z axis of the field remain perpendicular to the xy plane. I would like visualize what happens to this new vector field.
