  1. Séquin’s Professional Interests Design CAD-CAM Graphics HCI Geometry Art Art-Math

  2. I Love to Build Things … CCD Camera, Bell Labs, 1973 Soda Hall, Berkeley, 1994 RISC chip, Berkeley, 1981 “Octa-Gear”, Berkeley, 2000

  3. CADAM: Rapid Prototypingwith Paul Wright (ME) Physical Rapid Prototypes: • For early user testing, • and hands-on feedback • in application context. Zcorp 3D-printer FDM

  4. EE – ME Design Domain Coupling(with Paul Wright, ME) Button Mote Design from NEST Group Coupling • PCB Contact Pads and Lid Access Holes are considered features. • Access Holes are coupled to Contact Pads geometrically by position and size. • Alteration of center location of Contact Pads (Electrical Domain) will drastically effect Access Holes (Mechanical Domain) center locations.

  5. Art-Math Connection

  6. V-art VirtualGlassScherkTowerwith MonkeySaddles(Radiance 40 hours) Jane Yen

  7. Brent Collins “Hyperbolic Hexagon II”

  8. Snow-sculpting Championship 2003

  9. CAD tools for Ideation, Informal Prototyping • Mimick the best of: clay, wire, paper, scotch-tape, styrofoam … • Without the adversity of: messy glue, gravity, strength limits … • Make available pseudo-physical materials that bend as nicely as steel wire, and stretch like a nylon hose, but are strong as titanium, and as transparent as quartz …

  10. Tele- Collaborative VR Workstation for Designing Across the Internet(with Sara McMains, ME) See in 3D, Touch, feel, Annotate, Modify, Share, Discuss …

  11. Collaborative VR Workstation A student interacting with a Ford Explorer model displayed on the workstation (simulated 3D effect showing the part where the user perceives it to be).

  12. Model Annotation Drawing on a virtual bunny with a brush tool with haptic force-feedback.

  13. Better Surface Design Tools • Based on optimization of a functional • E.g., MVS for aesthetics(Minimum [curvature] Var.) • Fewer controls to manipulate • Explicit consideration of constraints • Automatic attainment of some quality objectives.

  14. Smooth Lines on Smooth Surfaces(+ partitioning along these lines) • Given a smooth surface, and some tiling symmetry group:  cut the surface up accordingly with smooth boundaries.

  15. Escher-like Tiling Patterns on Higher-Genus Surfaces 60 Tiles on Genus-0  168 Tiles on Genus-3

  16. The New CITRIS Building • Extension of Berkeley Walkthru: • Visualization, Energy Analysis, Emergency Response …(thousands of sensors).
