I have a requirment to take a bunch of ball images, and animate their locations overtime following a curved path.

The scene should ultimately look like a bunch of balls bouncing around in a blower.

Then I would like to output that animation scene to an animated gif.

Are there any free applications that would be suited to this?

So far I have uncovered http://www.synfig.org/

The ultimate free tool for doing this sort of work, (but with quite a steep learning curve), is Blender 3D which is a modelling, rendering, animation, video creation and editing suite - there is even a physics engine that would allow you to make your animation real world accurate.

  • Free, Gratis & Open Source
  • Cross Platform
  • Selectable detail level up to hi-res photo realism
  • Physics Engine
  • Strong user community
  • Lots of online examples
  • You can either output as a video file or as a sequence of frames for later conversion to gif with Image Magick or GIMP as in this tutorial.

    Ok I will give it a try. I already have used blender for video editing and modelling. I should have known it does more.
