The marching shape: Extensions to the Ice-Ray shape grammar

Abstract

Contemporary voxel based CAD software uses a predetermined voxel space as a property placeholder for establishing relationships between boundaries and properties (weights). The Marching Shape algorithm, developed as an extension of the Ice Ray Shape Grammar, demonstrate how similar relationships between weights and boundaries can be developed without the fixed structure of Voxels. An extended Ice-Ray is presented that includes rules and schemas for polygons of more than 5 vertices, rules for the manipulation of weights as well as rules that establish relationships between them.
