Parallel program design and analysis is a complex activity, where many difficulties stem from the principle inadequacy of pure textual formalism to specify parallelism in an understandable fashion. In this paper we report on a visual system, which uses a three dimensional model to describe the data dependencies in the computational domain and to visualise transformations of this domain relevant to the main steps in parallel program design. We believe three dimensional interactive graphics provides an extra degree of freedom for conveying information. Using 3D graphics, we can visualise all the data dependencies evolving in time as a three dimensional graph, displaying it on a screen. Visual abstraction, animation of transformations and visualisation of their effects will shift information to the perceptual level to help assimilate mathematical notions.
