Web20 de dez. de 2012 · Angle Ranges for the Thumb and Index Fingers. The index finger can turn between 60 and 120 degrees around the COG, while the thumb can move between 120 and 200 degrees. I arrived at these angles through trial-and-error, and they assume that the hand is orientated straight up. Web4 de mar. de 2013 · angle range is unspecified (neither before nor after). Also algorithm's implementation doesn't define even width/height relations (can be swapped with 90 degree angle adjustment). For example, if we want to force width >= height, then angle range's size should be 180 degrees.
