“Object (with axis-angle rotation)” animation swings forth and back instead of doing a circular movement

Home / Page / “Object (with axis-angle rotation)” animation swings forth and back instead of doing a circular movement

Description

When animating a scene object using the “Object (with axis-angle rotation)” animation type with angles of 360° or more it can happen that instead of a circular movement the animation swings forth and back.

This happens if you use only three evenly distributed key frames to describe the circle (e.g. 0°, 180°, 360°). The animation algorithm always takes the shortest possible route to the next key frame. If there are only three keys defined the distance from 180° to 360° is the same as from 180° to 0° which causes the wrong behavior.

 

Solution

There are two possible solutions for this:

  1. Use four or more evenly distributed keys to describe the circular animation (e.g. 0°, 90°, 180°, 270°, 360°).
  2. Use the “Object (with Euler rotation)” animation type instead.
