Computer-assisted vs. computer-generated




To animate means, figuratively, to "give life to". There are two basic methods that animators commonly use to accomplish this.

Computer-assisted animation is usually classed as two-dimensional (2D) animation. Drawings are either hand drawn (pencil to paper) or interactively drawn (on the computer) using different assisting appliances and are positioned into specific software packages. Within the software package, the creator places drawings into different key frames which fundamentally create an outline of the most important movements. The computer then fills in the "in-between frames", a process commonly known as Tweening. Computer-assisted animation employs new technologies to produce content faster than is possible with traditional animation, while still retaining the stylistic elements of traditionally drawn characters or objects.

Examples of films produced using computer-assisted animation are The Little Mermaid, The Rescuers Down Under, Beauty and the Beast, Aladdin, The Lion King, Pocahontas, The Hunchback of Notre Dame, Hercules, Mulan, The Road to El Dorado and Tarzan.

Computer-generated animation is known as three-dimensional (3D) animation. Creators design an object or character with an X, a Y and a Z axis. No pencil-to-paper drawings create the way computer-generated animation works. The object or character created will then be taken into a software. Key-framing and tweening are also carried out in computer-generated animation but so are many techniques unrelated to traditional animation. Animators can break physical laws by using mathematical algorithms to cheat mass, force and gravity rulings. Fundamentally, time scale and quality could be said to be a preferred way to produce animation as they are major aspects enhanced by using computer-generated animation. Another positive aspect of CGA is the fact one can create a flock of creatures to act independently when created as a group. An animal's fur can be programmed to wave in the wind and lie flat when it rains instead of separately programming each strand of hair.

A few examples of computer-generated animation movies are Toy Story, Antz, Ice Age, Happy Feet, Despicable Me, Frozen, and Shrek.

46)All-woman BSF bikers create historical past with Republic Day presentación; Twitterati beam with take great pride in

India Republic Day -- To celebrate Indias 69th Republic Morning a grand parade was held in Rajpath in New Delhi like every year after Best Minister Narendra Modi paid homage to the nations martyrs by laying a wreath at Amar Jawan Jyoti. But this time around the on-lookers were in for a splendid wonder when a newly-formed Border Security and safety Forces Womens Motor Cycle crew Seema Bhawani made a spectacular debut with their daredevil stunts at the parade. Led by means of Sub-Inspector Stanzin Noryang the actual squad performed breathtaking stunts for the audience including a salute to the President! Out of the 12 stunts an d acrobatics fish riding side riding faulaad prachand baalay shaktiman hoke fighting sapt rishi seema prahari bharat ke mustaid prahari sarhad ke nigheban and flag march pyramid were the highlights.

Animation methods

In most 3D computer animation systems, an animator creates a simplified representation of a character's anatomy, which is analogous to a skeleton or stick figure. They are arranged into a default position known as a bind pose, or T-Pose. The position of each segment of the skeletal model is defined by animation variables, or Avars for short. In human and animal characters, many parts of the skeletal model correspond to the actual bones, but skeletal animation is also used to animate other things, with facial features (though other methods for facial animation exist). The character "Woody" in Toy Story , for example, uses 700 Avars (100 in the face alone). The computer doesn't usually render the skeletal model directly (it is invisible), but it does use the skeletal model to compute the exact position and orientation of that certain character, which is eventually rendered into an image. Thus by changing the values of Avars over time, the animator creates motion by maki

Explanation

To trick the eye and the brain into thinking they are seeing a smoothly moving object, the pictures should be drawn at around 12 frames per second or faster. (A frame is one complete image.) With rates above 75-120 frames per second, no improvement in realism or smoothness is perceivable due to the way the eye and the brain both process images. At rates below 12 frames per second, most people can detect jerkiness associated with the drawing of new images that detracts from the illusion of realistic movement. Conventional hand-drawn cartoon animation often uses 15 frames per second in order to save on the number of drawings needed, but this is usually accepted because of the stylized nature of cartoons. To produce more realistic imagery, computer animation demands higher frame rates. Films seen in theaters in the United States run at 24 frames per second, which is sufficient to create the illusion of continuous movement. For high resolution, adapters are used.
