The script in frame 3 duplicates the lines and points into the appropriate levels and sets initial values for some of the variables that will be used in the movie. It also sets some stage objects to invisible until theyΓÇÖre needed later in the animation.
Of special note is the variable "perspective" which has a value that will be used to calculate the ΓÇÿcamera lens angleΓÇÖ or the amount of perspective distortion. The lower the number, the more perspective distortion will occur. It is used in conjunction with "depth" in frame seven to distort the view to simulate a depth of field effect.
The next series of frames are responsible for the actual animation, user interactivity, 3D calculations etc. and consist of two frames that continually loop while calling scripts from the remainder of the frames. They are:
2. Main Looping Script
Frame 4 (label: Main Looping Script):
This frame contains the main looping script that calls the scripts to be executed in frames 6,7 and 8.
