For the beach ball above, use the #Hoods - Basic Sphere
preset, on a new layer, as a starting point:
Change the Rainbow>Linear layer to Rainbow>Radial.
Move the crosshairs to an off-center position.
You can use the Rainbow>Beam filter for longitudinal
When you have the colors and frequency you want,
apply the preset.
As far as I know, most applications have a Spherize
filter. Use this to create the 3D effect. Easy huh?
If you have ugly striping at the focal point of the ball,
or want to draw more attention to the focal point, select inside this area
and fill it with the appropriate color. (See below.)
For an illusion of bouncing, create a
feathered ellipse on a layer below the ball, move, distort, blur
and change opacity to your own taste.
