How to quantify a 3D picture

Hi
I have two questions. Firstly i have a project in which i need to quantify images of natural sand. For instance working out the diameter volume from images of natural sand. I can do this in 2-Dimension. However I have to do this 3-Dimension.
How do i incorporate 3d images into matlab and how can i quantify it.
Can anyone advise please?
Thank you

How are you generating the 3D image? Is it true volumetric 3D data like from a CT instrument, where you have an intensity for each and every x,y,z location? Or is it pseudo-3D data like from stereo cameras or a profilometer, where you don't have data at every x,y,z location but just at 1 z location (in essence it's a surface, not a volume)?

That does not look like a slice. It looks like a particle sitting on a black paper. If you do have actual slices, then you can cat them together like that (in fact I'm pretty sure that's my code that you got from somewhere). Many of the routines that work in 2D also work in 3D, so you can just go ahead and try it.
