DESCRIPTIONThis action computes transformation matrices for a given subgraph. It computes the cumulative transformation matrix and its inverse, along with a cumulative texture transformation matrix and its inverse. This ​action is unlike most others in that it does not traverse downwards from groups. When applied to a node, it computes the matrix for just that node. (This makes sense for transformation nodes, but not for ​others, really.) It is much more useful when applied to a path. When applied to a path, it gathers the transformation info for all nodes in the path and those that affect nodes in the path, but it stops ​when it hits the last node in the path; it does not traverse downwards from it as other actions (such as rendering) do. This behavior makes the most sense for this action.

METHODS\f8SoGetMatrixAction\*(Cr(const SbViewportRegion &newRegion)
Constructor takes viewport region to use for picking. Even though the matrix computation may not involve a window per se, some nodes need this information to determine their placement. \f8setViewportRegion\*(Cr(const SbViewportRegion &newRegion)
\f8getViewportRegion\*(Cr() const
Sets/returns current viewport region to use for action. \f8getMatrix\*(Cr()
\f8getInverse\*(Cr()
Returns cumulative transformation matrix and its inverse. Warning: the matrices returned by these routines should not be changed (unless you are implementing your own transformation nodes). \f8getTextureMatrix\*(Cr()
\f8getTextureInverse\*(Cr()
Returns cumulative texture transformation matrix and its inverse. Warning: the matrices returned by these routines should not be changed (unless you are implementing your own transformation nodes).
