CAD Tools for Aesthetic Engineering

Abstract

The role of computers and of computer-aided design tools for the creation geometrical shapes that will be judged primarily by aesthetic considerations is reviewed. Examples are the procedural generation of abstract geometrical sculpture or the shape optimization of constraint curves and surfaces with some global “cost” functional. Different possibilities for such “beauty functionals” are discussed. Moreover, rapid prototyping tools based on layered manufacturing now add a new dimension to the visualization of emerging designs. Finally, true interactivity of the CAD tools allows a more effective exploration of larger parts of the design space and can thereby result in an actual amplification of the creative process.
