# Some Ideas for Your CS285 Course Project . . .

## The more of the official course topics: "Procedural Design" -- "Solid Modeling" -- "Rapid Prototyping" a project can cover, the better!

• "A_MAZE_ing Shapes" -- Put a maze on the Stanford Bunny.
Make a simple maze generator for a square region. Suitably place and connect such maze-squares on a quadrilateral mesh of the Stanford bunny model (or some other fancy non-polyhedral shape). Kaplan's Tiled Bunny

• 3D Escher Tiling
Create a fancy 3D shape that tiles 3D space. It may be of a genus larger than zero!
Demonstrate stackability with a few solid tiles fabricated on the FDM machine. My 2008 Bridges paper

• Bas Reliefs
Creating an interesting bas-relief with FDM, using a method similar to:
Weyrich et al.: “Digital Bas-Relief from 3D Scenes”

• Sophisticated Gear Clusters
Create some planetary gear like this one or some fancy polyhedral gear like this or like this ...

• Non-circular 2.5D Gears
Fabricate some unusual, non-circular gear combinations -- inspired by:  http://www.mekanizmalar.com/

• Jitterbug Linkages and Hoberman Spheres
Design, analyze, and model as a kinematic (SLIDE?) file a cluster of mechanical linkages that transforms in intriguing ways.

• Generator for Urban Models
Write a program module that generates houses, city blocks, or larger urban structures.

• Some Shape Generator
Design a program for the production of stylized flowers, weird creatures, or some artistic geometric shapes.

• Unusual Bells
Design an intriguing bell shape with a few parameters to change this shape
-- and possibly simulate its FEM model for sound analysis.

• Symmetry Finder
Try to find the inherent (approximate) symmetries in the shape of a scanned in object or some other (irregular) mesh ... (perhaps by eigen-analysis?).

• Construction Kit Prototype
Design a system of tiles that can snap together into 3-dimensional, non-2-manifold cellular structures.

• A Better(?) Lego Block
Design novel "lego" bricks with interesting assembly possibilities;
-- for instance,
based on the decomposition of space into rhombic dodecahedra (closes sphere packing);
-- or inspired by the two rhombic Zonohedra bricks that allow aperiodic (Penrose) tiling of 3-space.

Also take some inspiration from the project titles from previous years:
• 2007:
• Mark Howison: "7-around Surface"
• James Andrews & Ming-Hay Luk: "FiberMesh++"
• Bryan Klingner: "SpaceKnit"
• 2006 Project Icons

• 2002:
• Sean Kim: "4D to 3D Projections in Tcl/SLIDE"
• Bryan Liu: "Wankel Engine model (FDM)"
• Jeff Schoner: "Non-circular Gears (FDM)"
• Ali Lakhia: "From Point Cloud to 3D Printing"
• Larry Miller: "Klein-Surface Decomposition"
• Young Shon: "Escher Tiling on the Torus"
• Kiha Lee: "Injection Mold for Triacontrahedral Tile"

• 2000 Project Titles:
