// .NAME vtkHomogeneousTransform - superclass for homogeneous transformations
// .SECTION Description
// vtkHomogeneousTransform provides a generic interface for homogeneous
// transformations, i.e. transformations which can be represented by
// multiplying a 4x4 matrix with a homogeneous coordinate.
// .SECTION see also
// vtkPerspectiveTransform vtkLinearTransform vtkIdentityTransform

// Description:
// Apply the transformation to a series of points, and append the
// results to outPts.

// transform is Updated first, to guarantee that the matrix
// is valid.
void GetMatrix(vtkMatrix4x4 *m);
// Description:
// Get a pointer to an internal vtkMatrix4x4 that represents
// the transformation. An Update() is called on the transform
// to ensure that the matrix is up-to-date when you get it.
// You should not store the matrix pointer anywhere because it
// might become stale.

// This will calculate the transformation without calling Update.
