How does animation work?
Basically, the program controls a scene, with several parameters.
Some parameters describe object positions, and others control the
camera. Each of the parameters may change through time.
To create an animation, the following loop repeats:
- increment time by one step.
- update the scene parameters.
- re-draw the updated scene.
What happens after the scene is updated? One of two things:
- nothing.
- the current frame (image) is saved to disk.
We save frames to disk, so that we can assemble them into a movie
file. I have prepared some instructions
on creating an MPEG movie file.
