Motivation

1972, at Bell Labs, I was laying out integrated
circuits one transistor at a time by hand.

1982, UCB, in the RISC_1 and RISC_2 chips,
most of the transistors were drawn and placed
by a computer program.

1992, major portions of most CPU chips are
designed and optimized by a IC compiler.

Study and accelerate this trend for the domains
of solid modeling and mechanical part designs.

Procedurally Designed Parts
My Examples:

Mathematical Objects, 4D Polytopes
(exact geometry, projections from 4D space)

Sculpture Families
(freeform, aesthetics, parameterize for variety)

Gears, Joints, Assemblies, Mechanisms
(interaction, vary gear ratios)

Puzzle or “LEGO” Pieces
(parameterize for mutual fit, tension)

Teaching Method
Learning by Doing

Listening alone is almost worthless.
Confusion before Understanding

You need to (want to) find a problem solution
yourself to understand it and remember it.
Teaching Style : ‘Socratic Method’

Relies on active participation of all students.

Some short homework assignments are
‘Design Exercises’ that have the purpose
to get your thinking started about some subject,
before the material is covered in class,
so that a more meaningful discussion can result.

Course Mechanics
Group Assignments:

Some assignments are individual, others in groups;
I may define those groupings initially, to make you
get to know one another and to foster collaboration.

Final Course Projects can be done alone or in pairs.
Grading Guidelines:

40% course project (several phases)

20% homework assignments (various sizes)

20% class participation (be here, on time, awake…)

20% paper presentations & (quiz ?)
