Practicing Rotational animation



This exercise is designed to be an application of the information learned in Chapter 3 of the Animation Bootcamp course.

The assignment is to animate a ball rolling across the floor. This application will introduce you to rotational keys and f-curves, which are a-whole-nother animal compared to translational f-curves. It will challenge your curve-to-motion coordination.



  1. Download the Rolling Ball Bounce: Source Files from the Downloads tab. Unzip and open the included .blend file with Blender.
  2. Key as few key-poses as possible to achieve a rolling ball animation with settle-to-stop.
  3. Render your animation as an openGL viewport render.
  4. Upload your video to YouTube or Vimeo.
  5. Finally, submit your exercise by clicking the Submit Exercise button in the top-right corner of this page and pasting your video’s URL.

    I have tried to calculate a length of circumference – the distance ball have to rotate on 360 degrees – then did a correct animation, and figered out that pisycly correct does not mean realistic looking. The best realistic looking results I achived when ball slide a little. Here is not a quastion, just observation
