The use of qualitative shape synthesis for the display of 3-D binary objects, is presented. Instead of the commonly used shading approaches, we propose that intrinsic shape features of the object(s) be the means for the display. The proposed approach is applicable to multi-object scenes and to outdoor scenery as well. It makes use of a new method, the diffusion process, that simulates diffusion of particles within the interior of a 3-D discrete object. Starting with initial concentrations of particles at the boundary-voxels, the diffusion procedure simulates the propagation of these particles inwards. Boundary voxels of the object are colored according to the concentration of particles obtained by suspending the diffusion process. This method assists shape characterization by providing a qualitative measure of boundary curvature and was used in achieving display of a variety of voxel-based objects. Examples of the use of this approach on synthetic, terrain, and range data, are provided.
