Computer Graphics Complete Reference Guide APK

Computer graphics is an art of drawing pictures on computer screens with the help of programming. It involves computations, creation, and manipulation of data. In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images.
The primary output device in a graphical system is the video monitor.
The operation of CRT is very simple −
The electron gun emits a beam of electrons (cathode rays).
The electron beam passes through focusing and deflection systems that direct it towards specified positions on the phosphor-coated screen.
When the beam hits the screen, the phosphor emits a small spot of light at each position contacted by the electron beam.
It redraws the picture by directing the electron beam back over the same screen points quickly.

Some excerpts are mentioned below.
“Animation means giving life to any object in computer graphics. It has the power of injecting energy and emotions into the most seemingly inanimate objects. Computer-assisted animation and computer-generated animation are two categories of computer animation. It can be presented via film or video.
The basic idea behind animation is to play back the recorded images at the rates fast enough to fool the human eye into interpreting them as continuous motion. Animation can make a series of dead images come alive. Animation can be used in many areas like entertainment, computer aided-design, scientific visualization, training, education, e-commerce, and computer art.”
“A keyframe is a frame where we define changes in animation. Every frame is a keyframe when we create frame by frame animation. When someone creates a 3D animation on a computer, they usually don’t specify the exact position of any given object on every single frame. They create keyframes.
Keyframes are important frames during which an object changes its size, direction, shape or other properties. The computer then figures out all the in-between frames and saves an extreme amount of time for the animator. The following illustrations depict the frames drawn by user and the frames generated by computer.”
