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. |
