Oh, interesting. I was confused by the float-to-int-and-back-again conversions in queryMatMap, so I thought this is precisely to prevent any interpolation and make sure the correct "slice" of the 3D texture is sampled. With this in mind I still think the texture array is a better option, and transition could be achieved by sampling twice from it. But at the moment with the current textures it does not make much of a difference anyway.
