// Description : Stores the total set of VertexSliders that the
|
|
// vertices in a particular GeomVertexData object might
|
|
// depend on.
|
|
//
|
|
// This is similar to a TransformTable, but it stores
|
|
// VertexSliders instead of VertexTransforms, and it
|
|
// stores them by name instead of by index number.
|
|
// Also, it is only used when animating vertices on the
|
|
// CPU, since GPU's don't support morphs at this point
|
|
// in time.
