Property Value

Type: SoMFFloat
Remarks

A time stamp represents the time at which a control point must be reached; the "scale" of the time is independent of the animation time. However, it is proportional to it. For example, if point 1 has a time stamp value of 10, point 2 has a time stamp value of 30, and point 3 has a time stamp value of 40, it means that the interpolation will take twice as long to go from point 1 to point 2 (20 time units) as it will to go from point 2 to point 3 (10 time units). The actual time to complete an animation, and therefore the overall speed, is determined by the time it takes for the OIV.Inventor.Engines.SoTrackFollower.alpha value to go from 0 to 1. In other words, the overall speed is controlled by the application or another engine which is updating the alpha input.

If a time stamp has a value of SO_UNDEFINED_TIME_STAMP (default value), then the computed time stamp is proportional to the distance between the previous and the next control point, i.e., speed is constant. If all the time stamps are set to SO_UNDEFINED_TIME_STAMP or are not set at all, they are all computed to be proportional to the distance between the points, and speed is constant over the entire track.

If the time stamp field contains one more value than the points field, the last time stamp is assumed to apply to the first/last control point in a loop. If fewer than 3 time stamps are provided, the track is interpolated proportional to the distance between control points.
