Choose Your Own Animated Background
A downloadable animation or 3D animation with the help of 3D animator usually happens in two ways. They are keyframe animation and motion capture. Keyframe animation is the most famous and oldest style of animation. In fact, these are examples of frame-by-frame animation. Modern keyframing techniques have arrived from early cartoons created by animation pioneers like Winsor McCay and Walt Disney. You may be surprised to learn that the keyframing techniques have not changed much. The thing that has changed is that the 3D software packages. These have made keyframing much easier to accomplish. This means a broader scope of artists can learn how to animate.
Keyframing is really changing the shape, place, spacing, or timing of an object in successive frames, with the major changes to the object being the key frames. In traditional 2D animation, every frame is generally drawn by hand. When frames are exposed in succession, as in a film, the small differences in each frame of animation create the illusion of motion. 3D software packages make keyframe animation easier by interpolating. When you are animating a falling ball, for example, one key frame might be of the ball in mid-air and the next key frame may be the ball touching the ground. Then the next key frame after that would be the ball squishing down as the impact deforms its shape.
Motion capture was first used sparingly because of the limitations of the technology, but it is witnessing increased acceptance in all things from video game animation to CG effects in films as the technique matures. Motion capture offers a nearness 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 . The data is then linked to the fix of a 3D character and they are translated into animation by the 3D software.
There are a couple of downsides to motion capture which makes it hard for beginning 3D animators to learn. Firstly is the cost of motion capture technology, which can run lots of money. This means that most new 3D artists should learn to include this animation style by importing motion capture data into a project from a commercially obtainable motion capture library.
