the difference of Java3d 1.6 version and 1.5 version

I want to know the difference of Java3d 1.6 version and 1.5 version ? From an understanding of the situation， java3d fusion JOGL；what's the very big change of java3d 1.6? for example:Rendering,Shadow，Efficiency,or more.Who can help me answer it, I am very interested, thank you so much.

I have change my 3D soft program from java3d 1.5 to 1.6, but i don't see a huge change, from The surface. Does it need some change in 1.6?

Hi

The public API of Java3D has mostly remained unchanged from the version 1.5 to the version 1.6. The biggest difference is that Java3D 1.6 uses only the renderer based on JOGL 2 whereas Java3D 1.5 uses several renderers depending on the platform, including one based on JOGL 1. As a consequence, the installation has changed a bit, JOGL 2 is a lot easier to install and deploy than JOGL 1. I advise you to read this tutorial:
