1. Collaborative Evolution of 3D Models Juan C. Quiroz1, Amit Banerjee2, Sushil J. Louis3, Sergiu M. Dascalu3 1Independent Contractor 2Pennsylvania State University, Harrisburg 3University of Nevada, Reno Wednesday, June 25, 2014

2. Outline 1. Creativity in Design 2. Collaborative Interactive Genetic Algorithms 3. Case study: 3D Modeling 4. Experiments and Results 5. Future Work

3. Design Creativity has the potential to occur when a designer purposely shifts the focus of the search space Goal oriented shifts while brainstorming and exploration are crucial to creativity Designers understanding of the problem changing over time or considering additional variables

4. Collaborative Interactive Genetic Algorithm

5. 3D Models Vertex programs sin(x) x + 10 cos(time)

6. X, YZ, Z Y, Z

7. Experimental Setup Design Phase 1. Individual 2. Collaborative 3. Individual 4. Collaborative 5. Individual 6. Collaborative 20 Computer Science Students

10. Evaluation 20 Computer Science Students Assess Creativity Novelty Value useful

11. Evaluation Statements A creative transformation is a transformation that is new, unexpected, and valuable. The transformation is creative. Extremely Creative Not Creative At All 1 7

12. Evaluation Statements The transformation is novel. Very True Not True At All The transformation can be used in a video game. Very True Not True At All 1 7

18. Online Evaluation Best individually created models Best collaboratively created models Evaluation Criteria Which of the two rows did you like the most? Which of the two rows is the most creative?

19. Results Which of the two rows did you like the most? 8 participants picked the individual row 7 participants picked the collaborative row 1 participant did not answer Which of the two rows is the most creative? 3 participants picked the individual row 13 participants picked the collaborative row Individual Collaborative NA Individual Collaborative

20. Discussion Different 3D models Lack of context Online Evaluation Scoring the row of individually created models first

21. Contributions and Future Work A new computational model of creative design Subjective exploration of solutions Integrates collaboration Expanding search space by adding variables Our model substantially changes resulting designs Future Work User studies addressing priming and confounding variable issues Do higher level transformations Machine learning
