John, the memory requirements for ValueGridPortrayal3D and
ObjectGridPortrayal3D are ghastly, due to certain of Sun's inefficient
design mistakes in Java3D. As discussed in the README file for
sim/app/particles3d, you need to increase Java's default memory heap.
It doesn't matter that your machine has 512 megs of memory: Java always
tops out with a small heap (20 megs or so is not uncommon). You can
increase the heap by running Java differently. On a Mac or OS X, it's
done like this:
java -Xmx200m sim.app.particles3d.Particles3DWithUI
I cannot say how to do it on Windows.
