This class is a container for an array of vectors. It will keep
|
||
|
|
track of whether the entire array of vectors is zero, and if not
|
||
|
|
where the non-zero vectors begin and end.
|
||
|
|
|
||
|
|
VectorChannelClass is used in exporting motion. Motion data
|
||
|
|
is broken into separate channels for X, Y, Z, and orientation.
|
||
|
|
Then if any of the channels are empty, they don't have to be stored.
|
||
|
|
The X,Y,Z channels all contain one-dimensional vectors and the
|
||
|
|
orientation channel contains four-dimensional vectors.
