Detailed Description

Structure that contain actual dimensions of data that is stored in volume texture.

It assumes that volume fills the cube [-1,-1,-1]..[1,1,1] and the texture coordinates scaled to [0,0,0]..[1,1,1] but volume itself can be less then whole texture. Correct coordinates of volume stored in texture could be computed as:

Xn = X * W Yn = Y * H Zn = Db + (Z - Do) * D

so X and Y just scaled, but Z should be modifyed according to proper range.
