Can I interpolate a raster from a 3D point cloud at a given elevation plane?

[David_Brooks]

I have a 3D point cloud of isosurfaces for soil types. The points contain a field for soil type, and the z values are such that the points exist in isosurfaces for each soil type.

However, I would like to generate rasters at horizontal height intervals (e.g every metre in Z), with pixels colour coded by soil type. This way, I will be able to build up a Multidimensional Raster Dataset, and then try to convert to Voxel model after this.

example of fixed elevation rasters. Mine would be coloured by 21 soil types
