CS 511: Topics In Computer Graphics

Objectives

• Provide understanding of the techniques, mathematical concepts, and algorithms used in warping, morphing, and texturing, in geometric modeling, and in animation (so as to facilitate further study in the area of computer graphics).
• Provide pointers into the literature and exercise a team project based on a literature search and one or more research papers.
• Practice software implementation of different concepts and techniques covered in the course.
• Utilize graphics and scientific tools for relevant software implementation.

Prerequisites

• CS 411, Linear Algebra.
