Thats the disadvantage of not having a delete keyword. I am still not
comfortable with this gc crap

Subject: Re: [JAVA3D] Out of memory!
I have no solution to your problem, since this is my problem too. Your
mail inspires me to seriously demand the guys at SUN to get garbage
collection working for Java3D. In my opinion it's by far!!! the most
important problem that needs to be solved, if you want to do at least
some useful things (more than a rotating cube) with Java3D. Perhaps
some of the Java3D developers have 256 MB of memory or more installed
in their computers (the bare minimum for serious work I think), but
how many of the users of the Java3D programs have this amount of
memory available?
Best regards,
Ingo
