The One Euro CHOP implements the One Euro Filter as described here: http://cristal.univ-lille.fr/~casiez/1euro/ After initially making this custom operator, the functionality was also included into the build in Filter CHOP. The one Euro Filter is especially useful when a person is in an interaction loop with TouchDesigner and wants quick response: It responds quickly to large changes in value, and it smooths out jitters in the input.
- Cutoff Frequency (Hz) - Decrease it if slow speed jitter is a problem.
- Speed Coefficient - Avoids high derivative bursts caused by jitter. (The research paper implementation fixes this value to 1Hz but defaults to )
- Slope Cutoff Frequency (Hz) - Increase if high speed lag is a problem.
