CSE5280 Mid-Term Topics

Below is a list of study topics for the mid-term exam:

• Classification or types of input devices
• Identify common display technologies (i.e. CRT, LCD,Active Matrix, Plasma) and their characteristics
• Have an understanding of shadow mask technology
• Definitions for flourescense, phosphorescence, flicker, critical fusion frequence (CFF), etc.
• Be prepared to determine if 2 lines are parallel, the midpoint computation, distance between 2 lines
• Identify 2 harcopy technologies, be prepared to discuss their key characteristics and how they work.
• Understand how to set up common 2D Transformation, including a shear transform.
• Understand the characteristics of affine transformations.
• Use catenation or composition to combine multiple primitive transformations using matrix multiplication. Why use composition?
• Why express points in homogenous coordinates? Must illustrate.
• Be able to describe the sequence of transformations that will transform the window shown to the viewport indicated, and give the matrix required for each. Calculate the coordinates of the labelled point or object where it appears on the screen.
