Computer graphics is mainly concerned with producing images or sequences of images (animation) using a computer. The hardware and software systems are used to make these images. Producing these Photo-realistic images is an extremely complicated task, but this field has great demand because of the limitless variety of applications. Computer graphics has grown enormously over the past two decades, and many software systems have been developed for generating computer graphics of various sorts. This includes the systems producing 3-dimensional models of the scene, rendering software for drawing these images, and the associated user interface software and hardware.
