By displaying a plan view of the camera and target, you can see where the clipping planes are located and visualize their effect on the scene. If the Camera Preview window is open, the clipping is displayed in the preview. Exercise 21-1 www.g-wlearning.com/CAD/ Complete the exercise on the companion website. Animation Preparation Animation Preparation The tools presented in this chapter make it easy to lay out a path, plan camera angles, and record the movement of the camera. The resulting animation can be directly output to a number of movie fi le types that can be shared with others. However, there are some decisions to make fi rst. It is important to plan exactly what you want to see in the animation. Think like a movie director and plan the “shots.” Ask these questions: • What will be visible from each camera angle? • Is there a background in place? • Is the lighting appropriate? • Will a simple walkthrough suffi ce or will a fl yby be necessary? • How close is the viewer (camera) going to be to the objects in the scene? The answers to these questions will help determine the modeling detail required. Do not model anything that will not be seen. Also, do not place detailed materials on objects that are not the focus of the animation.
