Can anyone please tell me whether can I subload a 3D texture?

I am trying to render a 3D volume, but the size is bigger than my
texture ram (my system is a High Impact w/ 1 TRAM). Can I then use
PFTEX_SUBLOAD_FORMAT, to load part of the texture which is suitable for
the TRAM, and render the volume by repeating the process.

>From the man pages, I see that pfTexture::setLoadOrigin and
pfTexture::setLoadSize has only 2 parameters, so I reckon this can be
used only on 2D texture. I would like to know whether can
PFTEX_SUBLOAD_FORMAT be used on 3D textures in Performer.

Can anyone please advice me on how to carry out the rendering of a large
3D texture on my system?

Thanks,

richard
