overview
Recent advances in 3D digital geometry processing have created a plenitude of novel concepts for the mathematical representation and interactive manipulation of geometric models. This course covers the fundamentals and some of the latest developments in geometric modeling and digital geometry processing. Topics include surface modeling based on polygonal meshes, surface reconstruction, mesh improvement, discrete differential geometry, interactive shape editing, skinning animation, architectural and structure-aware geometric modeling, geometry for 3D computational fabrication.
Course objectives
The students will learn how to design, program and analyze algorithms and systems for interactive 3D shape modeling and digital geometry processing.
Course work and performance assessment
There will be 4 mandatory programming + "pen-and-paper" assignments and one slightly larger programming project. A code framework will be provided that allows you to experiment with various algorithms without having to bother much about software infrastructure. The weight of the homework assignments in the final grade will be 80%. There will be a short written exam (multiple choice, 60 minutes) at the end of the semester, amounting to 20% of the final grade.
Prerequisites
Introduction to Computer Graphics or Visual Computing or a similar course, experience with C++ programming. Some background in geometric computing is helpful, but not necessary.
