ITCS 3120/6120-8120

Computer Graphics

Fall 2019

Dr. Zachary Wartell

 

Overview

General:  Introduction to Computer Graphics is a standard course on computer graphics as a discipline in computer science. This differs from a computer graphics course found in an industrial art and design department or a course found in a two year degree program that might cover how to use computer graphics applications or how to program in a 4th generation programming/scripting languages to develop 2D or 3D visual media presentations (VRML, Macromedia Flash, Unity 3D, etc.).   Other UNCC ITCS and ITIS courses cover such materials and topics.

ITCS 3120:
Course Catalog:
Introduction to graphics hardware; raster algorithms; event-based programming; shader programming; anti-aliasing methods; matrix algebra for change of coordinates and 2D geometric transformations; 2D viewing transformation and clipping; 2D curves and 2D splines."

Further, to the degree possible we also cover the basics of 3D transforms and viewing and basic lighting

Prerequisites: ITSC 2214 and MATH 2164 or permission of department.
ITCS 6120/8120:

Course Catalog:
Introduction to the design and implementation of interactive graphics systems. Raster and vector display systems, I/O devices; graphics primitives and their attributes; raster algorithms and clipping; 2D/3D geometric transformations; 3D viewing and projections; hierarchical and procedural models; surface representation; color and lighting models; rendering algorithms; global illumination and texture mapping.

Restriction(s): CCI graduate standing or permission of instructor.
Cross-listed as: ITCS 8120.
