Objectives and Learning outcomes of the Course Unit - To introduce the postgraduates into the broad field of computer graphics.
- To educate the postgraduates with strong skills in scientific research methodologies.
- To educate the postgraduates for a research career or an academic career in geometric computing and computer graphics. - Be able to deliver a time performance analysis of at least two convex hull algorithms.
- Be able to describe an efficient geometric search algorithm such as, for example, the 2-nearest points algorithm.
- Be able to explain the importance of function theory in representing geometric objects (i.e., curves, surfaces, and solids); in particular, students must be able to distinguish parametric from implicit formulations of geometry.
- Be able to identify at least a representation scheme for solids that is useful in the segmentation of human anatomical shapes in 3D medical imaging.
- Be able to develop a novel algorithm in geometric computing.
