CS 285: SOLID MODELING

EXAMPLES OF SOLID MODELING TASKS
(and possible subsequent fabrication)

1. How would you create a CAD model for an ordinary plastic spoon ?

2. What is involved in defining the shape of the injection mold for the spoon above ?

3. Given a complicated shape such as this smiling, Happy Buddha, we need a computer model of it that can be used in making a replica of this shape on a milling machine or with one of the layered solid free-form fabrication techniques.

4. How might one define the shape of a geometrical sculpture such as this "Flame" by Bathsheba Grossman ?

5. Take Escher's "Wooden Ball with Fish" as an example. Or take any other tiling pattern, e.g., "Angels and Devils" and map that onto a sphere as a bas-relief, so that it can be fabricated with SFF or by milling.

6. Maple sculpture carved by M.C. Escher in the form of twelve flowers in a dodecahedral arrangement.

7. Create a description of the individual parts of this Octa-Gear (= eight identical gear wheels on the faces of an octahedron) so that the parts can be manufactured and assembled.

8. Create a CAD model for a mechanical part such as this crankshaft or this rod bearing.

9. Create a 3D model for interactive visualization or fabrication of the most symmetrtical genus-6 surface with the complete graph of 12 vertices (K12) embedded on its surface . The 44 three-sided patches, and the 66 (curved) edges should be clearly visible.

10. Skeleton of a Klein Bottle; a lattice of beams that illustrates the shape of this famous one-sided surface.

11. Brent Collins' "Pax Mundi". A meandering ribbon hugging the surface of a sphere.
    
    
12. "Dodeca Pentafoil Tangle". A globe of interlocking knots.
    
    
13. A 3D Hilbert curve. This is an analogon to the famous space-filling 2D Hilbert Curve, suitably "fattened" so that it can be manufactured.
