CAD genetic algorithms for evolutionary form and function design

This paper describes research into the use of genetic algorithms within a computer aided design tool. In the early work the genetic algorithm allows the evolution of designs against a subjective rating carried out by the designer. Shapes considered by the designer to contain pleasing characteristics are used to generate subsequent generations of different but related shapes. Examples are given where the technique is used to generate ‘animal sculptures’ and a variety of concepts for seating. Current work concerned with the quantification of aesthetic measures and their inclusion within the genetic algorithm is briefly introduced.
