rvb Save Animation Frames

rvb animation snippet example

This snippet will show you how to automate frame recording with rhinoscript. We used this as part of the script for the parametric kinetic wall design. It is particullarly suitable for users who do not use Bongo, and would like to create animations. Also, you can try to turn this piece of code into a class for even easier reuse. Do not hesitate to contact us for further information on its possible uses.
