...beyond low-level geometric representations of 3D shape, is an element of shape intelligence: constructs that capture the essence of the shape, and facilitate meaningful interactive manipulation that automatically preserves important aspects of both form and function of the shape.

This course is designed to serve three purposes:

• to teach students fundamentals of 3D shape modeling: curve and mesh-based representations and geometric processing concepts such as curvature, deformation, segmentation and symmetry.

• to allow students to explore shape modeling in the context of interaction and fabrication using pen and touch, motion capture, VR/AR devices, laser cutters and 3D printers.

• to read, understand and present state of the art research papers in shape modeling and fabrication.

The course will also feature guest lectures by researchers and designers on approaches to go from visual concept to digital shape. As a graduate course in the Department of Computer Science, a solid background in computer science is expected. A background in computer graphics, HCI and an artistic sense are useful. The course format is 12 weeks of one meeting a week. Roughly 1/2 the meetings will be lectures and the rest will be tutorials, demos and paper presentations by students. The students will be graded on their technical and creative contribution to a modeling project (done in groups of 3 or less) that will account for 40% of the grade. A project report will account for 10% of the mark. A small assignment to design and model a physically functional object illustrating principles in Don Norman's Design of Everyday Things (groups of 3 or less) will be worth 25%.  The remaining 25% will be based on the presentation of a research paper in class.

   

Grading scheme

• modeling assignment 25%.
• paper presentation 25%.
• project 40% + report (1-4 pages) 10% (a mid-term evaluation will be worth 10 of the 40%).

Duration

 

First class will meet 15 Sept. 2015.

The class will meet once a week T 3-5 in BA 5187, the Dynamic Graphics Project lab (http://www.dgp.toronto.edu).
