Transformation Pipeline
The entire transformation pipeline that defines either a shape transformation or a group transformation is represented by the matrix T, defined at the end of this subsection.
Scaling and translation are produced by the following matrix:
.
The following matrix translates the bounding box to the origin in preparation for rotation and flipping:
.
Rotation and flipping are produced by the following matrix:
.
The entire transformation pipeline for one step in the group hierarchy is represented by the matrix
