1. ArchiDNA: A Generative System for Shape Configuration Doo Young Kwon Design Machine Group Dept. of Architecture, University of Washington

2. Outline 1. Motivation & Research Question 2. Related Work 3. ArchiDNA & Demonstration 4. Conclusion & Future Work

3. Motivation  Computer in a schematic design process  However, for designers still difficult to learn and control it.  To be a creative partner  easy to learn  easy to control  design knowledge  support inspiration

4. Research Question Can we program “DESIGN STYLE” into a set of “RULES” ? Can we program “DESIGN STYLE” into a set of “RULES” ? If so, can we “USE THE RULES” to develop a “GENERATIVE CAD SYSTEM” which expresses the design style?

5. (Stiny, 1977) Ice-Ray Grammar (Rule: 1)(Rule: 2)(Rule: 3)(Rule: 4) Part of derivations

6. (Stiny & Mitchell, 1978) Palladian Villa Grammar

7. (Koning & Eizenberg, 1981) Frank Lloyd Wright Prairie House Grammar

8. Design Style in ArchiDNA Peter Eisenman  The formal from the conceptual  Biocentrum Building Project (Biological Research Center, Germany, 1986)  Design Concept: DNA (A, G, C, T)

9. Eisenman’s 2D Drawing

10. Eisenman’s 3D Model

11. Rule Sequence Rule 1: Move Rule 2: Rotate Rule 3: Size Rule 4: Repeat anchor-edge

12. Derivation 1 B A B A A A A A A: applier-shape B: base-shape

13. Derivation 2 + B II B + A1A2 A1 A2 A1 A2 A1 A: applier-shape B: base-shape

14. Derivation 3 ++ I A3 I A1 + B + A4 A2 A: applier-shape B: base-shape

15. 3D Generation Rule B A C 1. Calculate the area of each shape 2. Assign the areas to the heights

16. 3D Generation Rule B A C 3. Compare areas with a “THRESHOLD” and decide up and down Extrusion of small shape B upward Extrusion of large shape C downward

17. Overview of ArchiDNA Define applier-shape Select base-shape 2D Shape Configuration 3D Form Generation

19. Conclusion & Future Work Conclusion  Creative partner which has a design style  Easy to use and easy to control  One shape to stylistic shape configurations  Very short time to generate formal design idea  Various 3D form generation Future work  Let the people use it !  Write a primer  Show various design examples  Use in a Design Studio  Extend to 3D form configurations *
