Re: [JAVA3D] 3D scene serialization problem

[Olivier fillon]

There was a thread on this before.. No you can not serialize as far as i know a scene (at least with j3d 1.1.*; It is very sad but it is so...) I need to check if there is something new under 1.2 any help welcome as it is a common problem: I solved it by doing my own serialization( restricted to my specific case)..not very nice Olivier Fillon    Minestar Project [EMAIL PROTECTED]  Mincom Limited Ph.+61-7-3303-3344               61 Wyandra Street Fax+61-7-3303-3232               Teneriffe Qld. 4005.

Or some native code ?   How i think ,it may be applied in games and 3d-editors or somewhere else.   Thank for attention , Andrei Karii .
