CENG789 - Digital Geometry Processing
Objective: Digital Geometry Processing is a subfield of Computer Graphics. This introductive course teaches the geometry processing pipeline, which involves reconstruction, analysis, manipulation, visualization, and fabrication. The practical applications implemented throughout the course content will make the student comfortable in engineering, medical, scientific visualization, entertainment (VFX/games), and many other related disciplines that make use of mesh models.
