Animation is the illusion of motion. It can be predefined, meaning the user cannot interact with it; or it could be dynamic, which is created by code and allows users to interact with the animation. You can move around 3D objects, the camera, and the light source. But animation is not only about moving things; changing the color, transparency, or shape of an object is also animation.
We have walked through several pieces of code that you can add in the render method and that enables the user to interact with the scene. In these examples, the concept of easing was introduced.
We have discussed Tweener, one of the available open source tweening engines, which can be used in combination with Papervision3D. A tweening engine lets you create and control tweens in an easy way. Tweener allows you to use quadratic Bézier curves, which are equations that define curved paths, meaning that we can tween the camera (or other objects) over a predefined curved path.
We have extended the basic keyboard...
