>Subject: [JAVA3D] ??? Two Locales and Behavior bug (sample code) ???
>To: [EMAIL PROTECTED]
>
>Hi,
>
>I'm facing a problem using two different Locales with different scenes.
>It seems like the position of the first Locale influences a behavior in
>the other one.
>In my sample program (see code below), I create a VirtualUniverse with
>two Locales, each with its own view. The MainFrame displays two
>(overlapping) Canvas3D objects with the two scenes.
>
>The first scene (=Locale 1) contains a cube which is rotated by a
>MouseRotator. The funny thing is, the position of Locale2 seems to
>influence the function of the mouse rotator. If I place the Locales 10m
>apart, everything works fine. If I place them apart 1000m, the
>MouseRotator doesn't work anymore. This has got something to do with the
>scheduling bounds of the MouseRotator, since if I increase the radius of
>its BoundingSphere to 1000, everything works again.
>
>So, is this a bug? I don't think the function of a behavior should be
>influenced by the position of a completly different locale...?
>
>Maybe I should add that I'm trying this on a Linux machine with the J3D
>1.1-pre-release. It would be nice if some of you could check whether the
>code runs on your machines (in the version below, on my machine the
>program displays the cube, but doesn't rotate it, although it should in
>my opinion).
>
>Please forgive me for the messy code, but this is a quick-and-dirty
>approach.(I have included some comments in places related to the bug,
>though :-)) - compile and start with "java MainFrame"

>thx
