    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
