shadowOnly Library Method
Short Description: Control display of shadows on transition
Signature: t.shadowOnly ([enable])
Group: Light and Shadow
Class: transition Class
If enabled (enable=true or missing) then only the shadows on
the element are drawn, not the element itself. The idea is that
the user makes sure that the element itself is drawn using
HTML+CSS while taccgl™ draws just the shadows on top of that.
Note that in contrast to castShadow, which controlls the
shadows casted by this transition on other
transitions, shadowOnly controlls the shadows other
elements or objects cast on this transition.
Using LightAmbDiff and lightBgAmbDiff the color of the shadow
can be controlled.
The color and texture of the element becomes almost irrelevant, since
only the shadow but not the element is drawn. The texture is however
relevant in so far as no shadow is drawn where the texture is transparent
while there is no or a transparent background color given. If on the other
hand a non-transparent color is given, then shadows are shown throughout the
animated element and the texture becomes completely irrelevant.
