Summary This component genarates temporal interpolating trajectories from a keypoint list. The linier function and quadratic function can be used as interpolating functions.
Strong Points Users can choose extracting mode: "ErrFix" mode, "KeyPointNumFix" mode and "IntervalFix" mode. The "ErrFix" mode fixes maximum interpolation error. The "KeyPointNumFix" mode fixes total key point number. And the "IntervalFix" mode fixes interval time between keypoints.
Limitations The maximum number of KeyPointNum is 256.
Known Problems NONE
Parameters ExMode = Select "ErrFix", "KeyPointNum" or "IntervalFix" for specify using
extracting mode.
Degree = Specify the degree of interpolating functions : 1 or 2.
ErrLimit = Specify the maximum error limit of "ErrFix" mode.
KeyPointNum = Specify the total key point number of "IntervalFix" mode.
Interval = Specify the Interval time of "IntervalFix" mode.
