3D object comparison with geometric guides for Interactive Evolutionary CAD

© 2017 The authors and IOS Press. All rights reserved. 3D object comparison is presented as part of research into guided evolutionary Computer-Aided Design (CAD). CAD technology in development will combine human interaction and geometric optimization, within an existing evolutionary design system (EvoShape). Geometric Guides consist of simple 3D target objects (bounding volumes), to which evolving forms are compared. Before comparison, objects must be aligned and scaled, a process known as Pose Normalization (PN) in the literature. Both PN and object comparison have been implemented using standard geometric functions, enabling populations of evolving forms to be directed by the Geometric Guides. The algorithms and their implementation are presented alongside early results and analysis, discussion on limitations and robustness, and their suitability for Interactive Evolutionary CAD.
