动作动画的19个常见缺陷（19 common defects in motion animation）

动作动画的19个常见缺陷（19 common defects in motion animation） 19 common drawbacks of CG animation (reasons and solutions) Author: Jeremy Pictures Imageworks2002 Sony Cantor animation director in May 4th Compile: Luonaldo Date: August 13, 2004 1) Fear Technology Reason: we are always afraid of things we dont know. The fear of computers, or the belief that it is omnipotent, is due to the lack of a good understanding of the basic working principles of computers. The solution: to know enough about computers so as to know their strengths and limitations. Remember, computers arent magic devices. It can not think. It only runs programs. It cant do what no one can do; it just does it faster. Its just a tool. A very complicated pencil. If the user has learned how to speak the language of the computer, then he is the master of the tool. There is no other way. 2) exercise is too mechanical... Rectilinear Reason: let the computer simply draw a linear f-Curves without slowing in and out. The solution: understand how f-Curves is converted into motion. Learn and apply the basic principles of animation. Appropriate manual addition of slow in and slow out key frames. The software I used for computer animation first created only linear key frames, and there was no f-Curves editor at all. I cant bend the ramp straight to make slow and slow, so I have to rely on the traditional animation principle to achieve this effect 3) or on the contrary: exercise is too curve, soft, computer feeling too strong Reason: let the computer do too many unsupervised work. The CG software usually creates a smooth f-Curves automatically when you set the keyframe, and the soft movement comes from just letting the f-Curves stay in its default shape. Thats why the eraser is the easiest animation in the CG, because the default f-Curves curve leads to an elastic movement. The solution: dont trust the computer to make the correct shape of the f-Curves. Learn how f-Curves is translated into motion, and accordingly deal wit
