Sorry my english..
Hi all.
I modified the HelloWorld aplication for experimentation with locales,
I undestood that the locale specifies the reference point of the objects,
so if I have two locales with two Canvas and two Views and only one scene
and the two locales are at 0,0,0 I can see the objects in the two views but
if I change the reference point in one locale the object is viewed at the same
place, I think I am doing somthing bad.
And of curse Mery Cristmas for my Java 3D friends and my best hopes
for you for the next year. :-)
