|
* This track is supposed to be Lighter in memory than CTrackKeyFramerTCBQuat, and also is maybe faster.
|
|
* The track is an oversampled version of CTrackKeyFramerTCBQuat (or any quat interpolator), to 30 fps for example,
|
|
* but each key is 9 bytes in memory, instead of 96.
|
|
* Only linear interpolation is performed (use CQuat::slerp) between 2 keys. And Keys are precomputed
|
|
* to be correctly on the same quaternion hemisphere from the preceding to the next.
|
|
*
|
|
* 9 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).
|
|
* 8 byte for a light normalized quaternion: x,y,z,w are stored in 16 bits.
