java3D gradient stepped shadows.
I am turning off the default java3d shadow spot to do interpolated, calulated shadows.
I have understood how to calculate and position a 3D shadow shape, and even how to have it transparent.
However, if I want a realistic shadow with curved or straight gradient stepping (as appropriate), I have a slight problem.
SE java contains the GradientPaint and RadialGradientPaint classes. However, they can only be used in 2D,
and don't automatically extend to 3D.
If I don't want to use static Textures and want an object and its shadow moving, is there a free for use GPL or similar
set of Shape3D gradient stepping classes?
