Without path dynamic response adaptation or path smoothing
The path-velocity characteristic has been obtained through deselection of path dynamic
response adaptation and path smoothing.
This corresponds to the following parameter settings:
$MC_ADAPT_PATH_DYNAMIC[1] = 1
$MC_LOOKAH_SMOOTH_FACTOR = 0%
With path dynamic response adaptation, without path smoothing
The path-velocity characteristic has been obtained through selection of path dynamic
response adaptation with minimum, and thus virtually inactive, path smoothing.
