Animation is defined as the rapid display of a sequence of images in order to create an illusion of movement. There are several techniques used in animation, namely traditional animation, stop motion animation, and computer animation. Nowadays, computer animation seems to be the way to go whether it be for a motion picture, video program or any other means of presenting animation.
Computer animation covers a plethora of techniques, with the unifying factor being that it is digitally created on a computer. There are two kinds of computer animation, namely 2D animation and 3D animation.
2D animation figures are created on the computer using 2D bitmap graphics or vector graphics. This includes computerized versions of a number of traditional animations techniques. 3D animation is digitally modeled and manipulated by an animator. While the results of the two techniques vary greatly, 3D animation actually relies on many of the same algorithms used in 2D animation.
A lot goes in to making a 3D animation, namely a variety of algorithms, mathematical functions, simulated fur or hair, effects such as fire and water and so much more. These can be achieved by using different techniques, including photo realistic animation, cel-shaded animation and motion capture.
Photo realistic animation is used mainly if the animator?s goal is for the animation to resemble real life. Using advanced rendering techniques, an animator can make detailed skin, plants, water, fire, clouds and just about everything under the sun, as close to real life as they can. Cel-shaded animation is used to mimic traditional animation using computer graphics software. Animators can make shading look stark and lessen the blending of colors. Motion capture is when a live actor wears a special suit that allows computer to copy their movements into computer generated characters. And that?s just a few of the techniques that fall under 3D dynamics. I believe that this is what makes 3D animation so popular these days.
3D animation techniques allow an animator to create a virtual world in which characters and objects move and interact. These techniques, when applied one on top of the other, also allows the images to seem more realistic. It is for this reason that many 3D animations are used as visual effects for movies, or make up whole movies, that have been released for the better part of the past decade.
Now you can produce 3d animations and 3d max animation like Pixar or Walt Disney easily and quickly from the comfort of your home…. with the same software that leading European studios are using. Visit 3DMagix.com – The advanced animation studio suite.
