Optimal 3D representation???

What would be the most efficient way of representing a 3D object?
In my application I'll need to apply convolution to a 3D object; this is not a problem for 1D or 2D:
1D. Ipp32f* myArray = ippsMalloc_32f( sizeX ); ...; ippsConv_32f( ... );
2D. Ipp32f* myMatrix = ippsMalloc_32f( sizeX * sizeY ); ...; ippiConvValid_32f_C1R( ... );
3D. ??? Maybe a vector of sizeZ, but then how to apply the convolution in the 3rd dimension
or a Ipp32f**, but again the same problem as before. And a really big Ipp32f* [sizeX * sizeY * sizeZ] gives me the same problem, how to apply the convolution on the 3rd dimension.
Thanks for any help and suggestion,
Boris

You might want to try using the Vector Statistical part of the Intel Math Kernel Library http://software.intel.com/en-us/articles/intel-mkl/ it handles multidimensional convolution which would include 3D convolution

Thanks for the tip Walter, it seems that MKL has what I need. However I was wondering if you know about future plans for IPP to include a multi-dimensional approach (Convolution, Fourier). I like these libraries very much and I would like to stay with them if possible. Thanks again for the suggestion,
Boris
