Computer Graphics Pdf Computer Graphics Pixel This is a pdf version of a free on line book that is available at math.hws.edu graphicsbook . the pdf does not include sample programs, but it does have external links to those files, shown in blue. the pdf also has internal links, shown in red. these links can be used in acrobat reader and some other pdf reader programs. Vector and bitmap graphics there are two basic types of graphics used in computer applications: bitmap and vector. vector graphics consist of lines and curves, that are defined by mathematical objects called vectors. shapes that we draw using computer softwares are vector graphics. Given two vectors use dot product (which will be in the graphics processor) to find the cosine of the angle between them. cosine is used extensively in computer graphics, for example in lighting calculations and in back face culling, which we’ll see as the semester progresses. Vector graphics are a flexible and scalable way to create images using mathematical equations and geometric shapes, unlike pixel based raster graphics. this method ensures that images maintain high quality and sharpness at any size, making them ideal for logos, illustrations, and other designs.

Vector graphics are a flexible and scalable way to create images using mathematical equations and geometric shapes, unlike pixel based raster graphics. this method ensures that images maintain high quality and sharpness at any size, making them ideal for logos, illustrations, and other designs. Shapes in vector graphics •the shapes in a vector graphics editor are usually restricted to those with simple mathematical representation, such as •rectangles (and squares) •ellipses (and circles) •straight lines •polygons •smooth curves •shapes built up out of these elements can be filled with color, patterns, or gradients. C. structured graphics 1. structured or vector (or object oriented) graphics treat the image as a collection of graphic objects such as lines, curves, and figures 2 represent objects using equations not pixels computer graphics. represent objects using equations, not pixels 3. resolution independent and scalable a. no pixelation 4. Vector graphics: in vector graphics, the image is represented in the form of continuous geometric objects: line, curve, etc. vector images are not based on pixel pattern.
