INTERACTIVE EVOLUTIONARY DESIGN • Evolutionary DesignComputer techniques that simulate principles of biological evolution to generate designs • InteractiveA person chooses which objects are ‘fittest’ and go on to createa new generation of designs
DEMONSTRATION • A person sits at a computer screen and decides which objects they like from a group (population) of 14. They can simply select objects or give some objects scores out of ten • These objects reproduce to form a new population • In a matter of minutes a series of generations are produced, generating interesting 3D geometry with no direct CAD manipulation
10 7 Generation One • Objects are created by interacting geometric primitives • Objects can be viewed individually using the CAD interface • The first population is randomly generated • In this case two objects are given ratings
7/10 The two objects rated from Generation One 10/10
Generation Two • The white object from the previous generation (given a score of 10)has produced the most children • From this population the white object is selected - no score is given, the object is just ‘clicked’ • A few of these objects have been affected by mutations
Generation Three • A whole population is produced from mutations of the selected object from the previous generation • From this population two objects are selected
1 10 1 Generation Four • Users control how influential the objects are via fitness scores • The curly shape is given 10 as it looks like a suitable form for an earring • Scores of 1-9 are probabilities, 10 guarantees selection as a parent.
10/10 The three objects rated from Generation Four 1/10 1/10
5 10 Generation Five • This population contains 7 new variations of the earring shape • The ring shape carries the same visual DNA as the earring shape • And a mutation that produces a ring shape! • The 10 rating will ensure it dominates the next generation
5/10 The two objects rated from Generation Five 10/10
Generation Six • Now we have a population containing 10 different ring variations • And a few other interesting shapes resulting from recombinations and mutations
Generation Six – Highlighted Objects • Since the system runs within CAD, material properties can be added
Generation Six – Highlighted Objects • The CAD system can also be used to edit the objects’ geometry
Generation Five – Highlighted Objects • There is no limit to the number of generations that can be produced
Generation Five – Highlighted Objects • Unique, interesting and useful forms are created with no need for CAD skills
