Greetings,It's been a few days since I've asked an alpha question, so here goes (sorry):
For comparrison and curiosity purposes, I decided to try my application with an upgraded java2 and java3d. I'm finding a difference in how my transparent wedges (created by Irregular2DSets) are rendered.
Using the older java:[java 1.4.2 (build 1.4.2-b28) and java3d-sdk-1.2.1_03 (blackdown) & VisAD circa May 2003]
I get this image: http://www.cimms.ou.edu/~kmanross/VCPRPE/VisADSamples/Alpha_noPattern_oldJava.gif With the newer java[java 1.4.2_03 (build 1.4.2_03-b02) and java3d-sdk-1.3.1 (blackdown) & VisAD Feb 2004]
I get: http://www.cimms.ou.edu/~kmanross/VCPRPE/VisADSamples/Alpha_Pattern_newJava.gif Notice in the purple areas of the newer version the wavy pattern.Is this a java issue and/or is there anything I can do to remedy this? I have tried using different transparency modes (NICEST, FASTEST) with no change in behavior.
Also, for more "standard" shapes, this does not seem to be an issue. I.e., plotting triangular wedges and making them transparent does not cause the wavy pattern for either version of java.
Many thanks!! -kevin. -- +------------------------------------------------------------+ Kevin L.
