Computer Graphics Tutorial

Computer graphics is a process to create pictures using computers. Usually, the term refers to computer-generated image data created in pixels with the help of specialized graphical hardware and software. It is also used for processing image data in pixels received from the physical world.

Multimedia is the field concerned with the computer-controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally.

This tutorial will help the students to understand the various algorithms of line drawing, circle drawing, transformations, line & polygon clipping, bezier & B-spline curve, compression etc. with interactive diagrams.

This tutorial app covers most of the major topics of computer graphics and multimedia subject. The contents of the tutorial are in PDF form. This tutorial describes all the given topics with clear diagrams. For the examination point of view, this app is very useful for all the students of computer science, information technology, and computer applications.
