Aims

To expose students to the challenges and potential of geometry processing in relevant application areas.

To explain how to use acquire 3D model, and subsequently process, analyze, and manipulate the data. 

To familiarize students with handling real data sets.

Learning Outcomes

Students successfully completing the module should be able to:

1. Read and understand recent advancements in this area. (theory)

2. Have a grasp of the key tools in geometry processing. (theory)

3. Gain necessary practical skills to work directly with real-world 3D data. (practice)

4. Be able to formulate and solve problem using the geometric tools they learn as part of the module. (practice)

The course introduces basics of geometry processing covering important aspects of acquisition, analysis, and manipulation of 3D data. The course will consist of a mix of theory and applications to real-world scenarios.

The course intends to introduce students to the various stages of a typical geometry processing pipeline. With recent growth in popularity of 3D acquisition devices and modeling frameworks, geometry processing is increasing becoming important in a diverse set of applications including city planning, architectural geometry, reverse engineering, interactive modeling, etc.

Topics will include but not restricted to mesh representations, mesh smoothing, remeshing, mesh reconstruction, and shape analysis. Necessary topics in differential geometry will be covered in the course.
