Happy New Year all!
I've been playing with the alpha/transparency attributes of VisAD and
have run into a problem with how I want to use it. I've read the
previous posts about alpha blending and am unsure whether this is the
same problem or not.
The basic problem is that I have several filled Irregular2DSets that I
am displaying with with ConstantMaps that include Display.Alpha. Many
of these Irr2DSets overlap and I was hoping that the overlapping
portions would "blend" the two colors and/or opacity of the respective
ConstantMaps.
To clarify, please see the right panel of:
http://www.cimms.ou.edu/~kmanross/VCPRPE/VCPRPE_AllBeamWidthsFilled.gif
Note the "filled beam widths", each of which has its own ConstantMap (as
well as DataReferenceImpl).
If we zoom in on the upper right corner of the right panel we have this
image:

Hopefully you can see how the beam widths overlap. The current behavior
is to simply overlay the next ConstantMap color, but I am wanting to
blend or merge the two ConstantMap colors and/or have their opacity
merged. Is there a way to do this?
Thank you very much for your help and time!
-kevin.
