VISUAL TECHNIQUES IN ANIMATION

Introduction:

Animation:

To ‘animate’ is literally, to bring into life . Although people often think of animation as synonymous with, it covers all changes that have a visual effect. It thus includes the time varying position, shape, colour, transparency, structure, and texture of an object, and changes in lighting, camera position, orientation, and focus, even changes of rendering techniques.
Animation is a graphic representation of drawings to show movement within those drawings. A series of drawings are linked together and usually photographed by a camera. The drawings have been slightly changed between individualized frames so when they are played back in rapid succession (24 frames per second) there appears to be seamless movement within the drawings.

Animation is widely used in the entertainment industry, and also being applied in education, in industrial application such as control systems and heads-up displays and flight simulators for aircraft, and in scientific research. The scientific applications of the computer graphics, and especially of animation, have come to be group under the heading scientific visualization. Visualization is more than the mere application of graphics to science and engineering, however, it can involve other disciplines , such as signal processing , computational geometry, and database theory. Often the animations in real visualization are generated from simulation of scientific phenomena. The result of the simulations may be large database presenting 2D and 3D data; these data are converted into images than then constitute the animation. At the other extreme, the simulation may generate positions and locations of physical objects, which must then be rendered in some form to generate the animation. This happens for example in chemical simulation , where the positions and orientation happens of various atoms in a reaction may show a ball and stick view of each atom or may show overlapping smoothly shaded spheres representing each atom. In some cases , the simulation program will contain embedded animation language , so that the simulation and animation processes are simultaneous.
