Im Keyframe Reduction

This tool performs keyframe reduction on an AnimationClip by using polynomial fitting.

The core script is licensed under CC0 1.0. It utilizes MathNet.Numerics, which is under the MIT license.

Usage

• Import the ImKeyframeReduction.unitypackage.
  • If you have already imported the MathNet.Numerics package, simply copy the core script into your project.
• Open the Window/Im/Keyframe Reduction window.
• Set the original AnimationClip, and leave the Output Clip field empty, then click Execute.
  • If the Output Clip field is not empty, the process will overwrite the existing Output Clip.

Note

• It is recommended to use Brute Force Mode to obtain accurate results.
  • Looking to fix...
• (TODO: UPM?)

Example

Input: TestInput.anim (983KB)

Output: TestOutput.anim (232KB), processed with default configuration (threshold = 1e-06, dt = 1/60, non-brute force mode).
