// Class : VectorDataTransition
|
|
// Description : A VectorDataAttribute is a special data graph
|
|
// attribute that is used to pass around a complex
|
|
// number like a vector or a matrix. The Transition
|
|
// isn't often used, but it may contain a matrix that
|
|
// modifies the vector in the attribute. (Note that a
|
|
// LMatrix4DataAttribute actually derives from
|
|
// VectorDataAttribute, even though its base type is a
|
|
// matrix, not a vector.)
