I just manage to write a programm for a lense where light is brocken on both surfaces. My problem is that i wrote the Programm like:
The animation is working, but from time to time there comes a error sound, and the Computer is not stopping calculating the animation...
is this the wrong way how to note down the programming?
the source code is in the attachment.
