Re: [JAVA3D] Out of memory

I remind that there was a bug (it was in j3d 1.2x) due ImageTexture using jpg's bigger then 1mb (or any rasterimage..unsure)... try to downsample bigger jpgs... thats the way I'd managed this 3 years ago...maybe today there's a better solution... I never try that what goalsgoals2004 has written...but sounds better :-) best regards rolf

Alessandro,
Thank you for your hint. However I am up to 512MB (I have 2GB in my computer but any more than -Xm512M makes the ATI driver blue screen â a question for another day.) Eventually whatever value I use I get the out of memory problem back. KRK in his problem got the out of memory problem only after repeated additions and deletions from his branch group â this is very similar to mine as I frequently change the scene graph.

Mike

an old topic.I find a mail about it on 2004-07-30:
ããOpen the Java Plug In Control Panel (Start|ControlPanel|JavaPlugIn) and click "Advanced" tab and at "Java Runtime Parameters" write -Xmx256m

You can increase the amount of max memory available to JVM just setting a value greater than 256. DO NOT forget the m sufix, for megabytes.
On Unix system (Linux included) the Control Panel can be found in the JRE
folder.

try to launch java -ms300m ...... where 300 mb is the maximum heap

you want for the applet (or application) . Of course your memory

be different...
Hope this helps

  Subject: [JAVA3D] encounter "OutOfMemory" when Applet reads 3D models
larger than about 5MB
  Hi,
I wrote an Applet that reads and displays VRML files. Everything
is fine
when the .wrl file is no larger than about 5MB. But when the total
size of
the .wrl file and it's .jpg texture excess 5MB, the JVM will always
throw a
"outOfMemory" exception. I'm sure the physical memory is sufficient
for the
program (512M RAM, WinXP). Has anyone encountered and solved this
problem?
Please help, thank you.

    Colleagues,
    In December 2000 KRK posted a note
    http://archives.java.sun.com/cgi-bin/wa?A2=ind0012&L=java3d-interest&F=&S=&P=36521
    
<http://archives.java.sun.com/cgi-bin/wa?A2=ind0012&L=java3d-interest&F=&S=&P=36521>
    to the list. His application runs out of memory when he attaches
    and detaches screen graphs in succession. I canât find any reply,
    but I have the same problem. Someone some where must know the answer.
    Thanks
