11.VEHICLES IN MOTION
The limits of animation as compared to live-action become very apparent when you desire to show a vehicle traveling along a road.The live camera can position itself wherever it is needed alongside or in the car and the background will recede into the distance as it does in real life.In animation,to get the same illusion you would have to animate the background and,indeed,this is a tchnique that can be used,although at quite a sacrifice.

You can put the car on a tilt pan,indicate it like this:

题目：运动中的车辆.
当你希望演示一辆从公路上经过的车时,动画的效果较之真实场景是相差甚远的.因为不管是需要在路旁摄影,还是尾随拍摄,或者在车中跟拍,相机都能够实时拍摄,及时调整位置.正如现实生活中的场景一样.背景会随之变化、拉长.
而在动画中,如果想得到同样的虚幻效果,绘制栩栩如生的背景.虽然某些技术能为之所用,实现同样的效果,但需要较大的成本.
但是,也有少数的办法能够显示出一辆运动中的车辆的状态.其中最简单的方法是,让一辆车移入能够反复的背景中.从而实现移进移出的效果,抑或缓慢的用镜头穿过场景.
你可以将此车辆放入一倾斜镜头,像这样：
里面有些专业术语,不大清楚,加上本人水平有限,只能这样了,大体还通顺吧,做了些润色.不过貌似这篇文章没有写完.
