Rotate a 3D wave

So in imageJ I would just use the reslice command for this, but I cant remember how to do this in Igor in a simple way without iterating thru the entire chunk.

Lets say I have a wave that has dimensions (2048,512,512). How do I rearrange it so I am looking down at (512,512,2048) without actually rearranging the data points in relation to each other?
You could try:
ImageTransform /G=3 transposeVol yourMatrix
It will put p,q,r to r,q,p
