Non-linear Morphing

Standard morphing entails linear interpolation between two adjacent key frames. This is sufficient for most situations but fails to produce good results when there is rotational motion. Non-linear morphing which involves a cubic fit between 4 key frames products superior movement but does result in a larger swf file size. If the non-linear option is selected and there are less than 4 key frames of motion, standard morphing will automatically occur. Non-linear morphing is only available in the Cartooning interface style.
