Detailed Description

+This track is supposed to be Lighter in memory than CTrackKeyFramerTCBVector, and also is maybe faster. +

+The track is an oversampled version of CTrackKeyFramerTCBVector (or any vector interpolator), to 30 fps for example, but each key is 13 bytes in memory, instead of 96. Only linear interpolation is performed between 2 keys. And Keys are precomputed +

+13 bytes per key is achieved by encoding this way: 1 byte for the length/key time, measured in samples, and not in second (hence we can skip at max 255 keys). 12 byte for the position. May be compressed in future to 6 bytes. +

+Build the track from a list of keys nlassert if ! same length. +

+

+Parameters:
+ + + + + +
timeList  +the list of key time. First must be ==0. nlassert if difference between 2 keys is > 255
keyList  +the list of keys, not yet compressed (done internally in future)
beginTime  +map to the timeList[0] time.
endTime  +map to the timeList[size-1] time.

+Evaluation of the value of the track for this time. +

+The result is internaly stored to simplify access at the polymorphic values. To get the value, call ITrack::getValue(). +
