Volume rendering problem

Hi all,

I downloaded and tested the AMD volume rendering example and it works fine.

But if I use an anisotropic volume (dowloaded from volvis, for example with spacing 1:1:4), the output isn't correct.  The object size seems incorrect and it doesn't rotate around its center. In the kernel code, there is the following comment:

" If the volume data is in format : 1:1:2 then sample z at a double rate"

I tried to change the z-coordinate used to read the input image and the object size seems correct, but the rotation center is wrong.

Any ideas?
