Triquadratic Reconstruction for Interactive Modelling of Potential Fields (figures 1 and 2)

Abstract

We present a data structure for three-dimensional fields C continuous in the modelling space. Regular grids storing the field values discretely are combined with a triquadratic approximation filter to define volume objects. This association of a grid and an approximation/interpolation filter allows the field to be defined by a C continuous real function and… (More)
