Abstract

Generic methods for the description of a complex system are sandpile (avalanche models), cellular automata, and couple map lattice (CML). The emergent phenomenology of these is broadband, but it is represented on a-finite grid. To study the three-dimensional evolution of a CML model of a sandpile as a function of control parameters, a semi-immersive VR environment has been used. Sandpile profiles are calculated in real time and are superimposed over the color grid that represents one of the control parameters. This represents a generic problem of visualizing multi-scale structures in data sets derived from nonlinear systems. The software modules were developed in OpenGL and Glut library and will ultimately be implemented in semi-immersive VR on an ImmersaDesk. To achieve sufficient speed in real-time display, the full data set is represented graphically in a compact form.
