You could use textures byref (by reference) and swap them back and forth.
Doing that would keep your memory at 2 textures, instead of 3.

Subject: Re: [JAVA3D] changing textures on the fly problem (fwd)
Ok, let me also ask this: when i modify the imagebuffer which i got from
one image component and then assign to anothe imagecomponent, isn't memory
allocated for the imagebuffer? if so, then it is pointless for me to
implement this "double buffering" which i was hoping to use to relieve the
need of allocating memory for every texture change. Isn't there a way to
change a texture and not allocate more memory, where i only need to change
one pixel or two pixels in the texture image?
