3D Film Technology

Technology of Three dimension Animation is source of huge currency reserve and its Effects  on human health:

 The time have passed when children see cartoon on PTV before going to school.  But today children like 3 D movie instead of cartoon.  Now we see what is 3 D Technology.

With the  help of Computer graphics we can give motion to unmovable things that they give the sight of living things.  In fact this illusion create by  a camera system.  We can make many cartoon, games, and movies with 3D.  In 1980 the Walt Disney do best to promote it.  Thus 3D did a lot of work from 2000 to 2011.


Animators must have a keen understanding of motion, movement, and acting. It may surprise you that the best animators take acting lessons - this helps them understand how their own body moves, and makes it easier to transfer that understanding into believable animation.

Keen observation may be the most important skill to develop as an animator. Observe life around you, and how things move. Make sketches, take notes, and try to give meaning to what you observe. Don't study just animation. Learn from film, theater, and even comic books to understand how poses and movement create moods and nonverbally communicate messages.

Good and Bad for human:

There is no doubt that these technologies give a lot of currency reserve in its fruit.
As the last year we have acquired 100 million dollar and we can get easily and surprise recreation in our life. 

Mean while we face  its bad effect on human life that is it effect on our eye sight.
  Our sight is move with the motion of movie seen it give result heavy and unrefreshed mind.
 Heavy light and technology are used in 3D which directly effect on our mind and eye sight.
Vomiting, headache, and eye weakness is the main effects.

Precaution:
people should  used 3D glasses to see such type of movies.
The 3D film maker should keep in mind the standard of its perspective.

The Techniques of 3D Animation:
Animation in 3D applications  in two primary ways, in major productions, both may be used.


I. Keyframe animation:  Keyframe animation, is the most well-known and oldest style of animation. In fact, there are examples of frame-by-frame animation dating all the way back to 1600 B.C. Egypt! Modern keyframing techniques date back to the early cartoons created by animation pioneers like Winsor McCay and Walt Disney. What may surprise you is that keyframing techniques have not changed much since the early 1900's - most of the basic principles still apply today. What has changed is that 3D software packages have made keyframing much easier to accomplish, meaning a broader scope of artists can learn how to animate.
Keyframing is essentially changing the shape, position, spacing, or timing of an object in successive frames, with major changes to the object being the key frames. In traditional 2D animation, each frame is usually drawn by hand. When frames are shown in succession, as in a movie, the slight differences in each frame of animation create the illusion of motion. 3D software packages make keyframe animation easier by interpolating, or "twining," the in-between frames. When animating a falling ball, for example, one key frame might be of the ball in mid-air, the next key frame may be the ball touching the ground, and the key frame after that would be the ball squishing down as the impact deforms its shape. All of the in-between frames are then calculated by the software automatically, including the squish at the bottom, making actual process of animation a matter of creating a few great key frames.

2.  Motion capture:   Motion capture, or mocap, was first used sparingly due to the limitations of the technology, but is seeing increased acceptance in everything from video game animation to CG effects in movies as the technique matures. Whereas keyframing is a precise, but slow animation method, motion capture offers an immediacy not found in traditional animation techniques. Mocap subjects, usually actors, are placed in a special suit containing sensors that record the motion of their limbs as they move. The data is then linked to the rig of a 3D character and translated into animation by the 3D software.
