1. BID Lab Opening, May 14, 2004

2. Design, Technology, and the Human Experience (the positive side) Carlo H. Séquin Computer Science Division

3. Technical Designs … CCD Camera, Bell Labs, 1973 Soda Hall, Berkeley, 1994 RISC chip, Berkeley, 1981 “Octa-Gear”, Berkeley, 2000

4. Aesthetic Designs … What is the role of the computer in: u aesthetic optimization, u the creative process ?

5. Collaboration with Brent Collins “Hyperbolic Hexagon II”

6. Brent Collins: Stacked Saddles

7. Scherk’s 2nd Minimal Surface Normal “biped” saddles Generalization to higher-order saddles (monkey saddle)

8. “Hyperbolic Hexagon” by B. Collins u 6 saddles in a ring u 6 holes passing through symmetry plane at ±45º u = “wound up” 6-story Scherk tower u Discussion: What if … l we added more stories ? l or introduced a twist before closing the ring ?

9. Closing the Loop straight or twisted

10. Brent Collins’ Prototyping Process Armature for the "Hyperbolic Heptagon" Mockup for the "Saddle Trefoil" Time-consuming ! (1-3 weeks)

11. “Sculpture Generator I”, GUI

12. V-art Virtual Glass Scherk Tower with Monkey Saddles (Radiance 40 hours) Jane Yen

13. Collins’ Fabrication Process Example: “Vox Solis” Layered laminated main shape Wood master pattern for sculpture

14. Slices through “Minimal Trefoil” 50%10%23%30% 45%5%20%27% 35%2%15%25%

15. u One thick slice thru sculpture, from which Brent can cut boards and assemble a rough shape. u Traces represent: top and bottom, as well as cuts at 1/4, 1/2, 3/4 of one board. Profiled Slice through “Heptoroid”

16. Emergence of the “Heptoroid” (1) Assembly of the precut boards

17. Emergence of the “Heptoroid” (2) Forming a continuous smooth edge

18. Emergence of the “Heptoroid” (3) Smoothing the whole surface

19. The Finished “Heptoroid” u at Fermi Lab Art Gallery (1998).

20. Various “Scherk-Collins” Sculptures

21. Rapid Prototyping by FDM

22. Hyper-Sculpture: “Family of 12 Trefoils” W=2 W=1 B=1 B=2 B=3 B=4

23. “Cohesion” SIGGRAPH’2003 Art Gallery

24. Snow-Sculpture, 12 Feet Tall

25. International Snow-Sculpting Championships Breckenridge, Colorado, January 2003

26. “Whirled White Web” Silver Medal Winner, Breckenridge 2003

27. “Whirled White Web” The Design Component: u Find a shape that has some aesthetic qualities as an abstract sculpture. u The shape should (roughly) fit the given snow block dimensions: 10  10  12 feet tall. u The shape must be strong enough to hold up as a snow sculpture. u The sculpture has to be constructible by a team of five during a 4-day period. u Also need a good title and a good story…

28. The Role of the Computer (1) Exploring different possibilities.

29. The Role of the Computer (2) Fine-tuning the most promising design

30. The Role of the Computer (3) Making a detailed 3D model

31. The Role of the Computer (4) Preparing construction drawings

32. Plenty of manual steps too … Making templates from computer prints, ( magnified with the classical grid method)

33. Removing lots of snow … Day 1

35. Day 2: Making a Torus

36. Day 3, pm: Flanges, Holes

37. Day 4: Geometry Refinement

38. Day 5, am: Surface Refinement

39. “House Cleaning”

40. “Whirled White Web”

41. Conclusions (1) u The computer plays an important role also for “Esthetic Engineering.” u Virtual Prototyping can save time and can tackle sculptures of a complexity that manual techniques could not conquer.

42. Conclusions (2) u The computer is not only a great visualization and prototyping tool, u It also is a generator for new ideas and u an amplifier for an artist’s inspiration.

43. Inspiration: Brent Collins’ “Pax Mundi”

44. UI for “Viae Globi” Shapes

45. Many Related Sculptures May Emerge

46. Discussion Topic What can we do in BID to help bridge the gap between Art and Engineering ?
