The Metasurface: Applying Natural Neighbour Interpolation to Two-to-Many Mapping

This report describes The Metasurface - a mapping interface supporting interactive design of two-to-many mappings through the placement and interpolation of parameter snapshots on a plane. The Metasurface employs natural neighbour interpolation, a local interpolation method based on Voronoi tessellation, to interpolate between parameter snapshots. Compared to global field based methods, natural neighbour interpolation offers increased predictability and the ability to represent multi-scale surfaces. An implementation of the Metasurface in the AudioMulch software environment is presented and key architectural features of AudioMulch which facilitate this implementation are discussed.
