// Description : This is an abstract template class that encapsulates
|
|
// all transitions that involve some kind of matrix,
|
|
// either a 4x4 or a 3x3, either float or double. It
|
|
// templates on the matrix type.
|
|
//
|
|
// It's the base class for a number of scene graph
|
|
// transitions like TransformTransition and
|
|
// TexMatrixTransition.
