Study Notes

AutoCAD and Drawings

Autodesk's AutoCAD is a software commonly used for creating 2D and 3D CAD drawings
The file format typically associated with AutoCAD drawings is .dwg

Analog vs. Digital Graphics

The main difference between analog graphics and digital graphics is the way the images are represented and processed
Analog graphics use continuous signals, whereas digital graphics use discrete digital signals

AutoCAD Software

The purpose of using AutoCAD software is to create, modify, analyze, and optimize digital designs
AutoCAD software is not used for creating bitmap images

Image Resolution

The primary determinant of the resolution of a raster image is the number of pixels used to create the image
The technique used to smooth out jagged edges in raster images is anti-aliasing
DPI stands for Dots Per Inch, measuring the density of print resolution
Vector graphics are not resolution dependent

Graphics and Resolution

Raster graphics are more likely to suffer from pixelation when enlarged
The number of colors that can be assigned to an individual pixel in a bitmap image is determined by the bit depth

Computer Graphics

The primary purpose of rendering in computer graphics is to generate an image from a model
The main difference between 2D and 3D computer graphics is the addition of depth in 3D graphics
The role of animation in computer graphics is to create the illusion of movement by displaying a sequence of images

Graphics Types

A raster graphic is best described as a bitmap image composed of a grid of pixels
The primary components of computer graphics are input, processing, and output
A raster graphic differs from a vector graphic in that it uses a grid of pixels, whereas a vector graphic uses mathematical equations to draw shapes
