One way to create computer animations is to create objects and then render them. This method produces perfect and three dimensional looking animations. Another way to create computer animation is to use standard computer painting tools and to paint single frames and composite them. These can later be either saved as a movie file or output to video. One last method of making computer animations is to use transitions and other special effects like morphing to modify existing images and video.
Computer graphics are any types of images created using any kind of computer.
There is a vast amount of types of images a computer can create. Also, there are just as many ways of creating those images. Images created by computers can be very simple, such as lines and circles, or extremly complex such as fractals and complicated rendered animations. If you want to create your own computer graphics, no matter how simple or complex, you have to know a few things about computers, computer graphics, and how they work.
