Possible to Animate by Variable?

Posted: Thu Mar 21, 2019 9:59 am
I've been toying occasionally with CF for a few years and I see the current version has an animation option when rendering. This seems to animate the rendering process itself, which is interesting, but something I would really like to do is create an animation where each frame is a full rendering and what changes between them is the value of a variable.

Is there are way to do this?

Perhaps is there a way to render from the command line with overrides for global variables passed as parameters? Then I could create animation by writing a script to render a series of frames.

This recent design shows how to make arbitrary animations.

There are two functions, frame() and ftime(), that allow for complex animation. If you don't use these functions and don't use time adjustments then animation simply animates the rendering process.

Time adjustments allow you to control which frames a shape is visible on. Using frame() or ftime() allows you to make you cfdg grammar change for each frame. I think that the time adjustment feature is too complicated. I don't think anyone has ever used it. I may add visibility mode to each shape that indicates whether the shape is visible in the current frame.

It is true that there should be a way to provide global variables at the command line (configuration variables too).
