opengl - Processing large image volumes -

i have huge 3d volume, sizes above 2gb. want load data, process , display in application 3d volume, in zooming , rotation of volume cn performed.

i saw applications loads huge info , displays it.

my uncertainty that, windows32 bit applications address space limited 2gb, technique used within these applications handle huge volume?

or

how can mange these huge info in application optimal performance?

my uncertainty that, windows32 bit applications address space limited 2gb

only on 32 bit systems.

then technique used within these applications handle huge volume?

using 64 bit system, gives address space of 234 gib. real bottleneck size of texture space on modern gpus. illustration doing such medical volume rendering , 2 gib gpu memory textures limited 1.5 gib still need space screen framebuffer , other resources.

how can mange these huge info in application optimal performance?

use 64 bit system. of course of study need amounts of scheme memory (ram). illustration toy workstation has 64 gib of memory.
