• Hierarchy of Transformations
  • Projective Transformations
  • Affine Transformations : A subgroup of P L(3) consisting of matrices having last row (0, 0, 1) is called an affine group.
  • Similarity Transformations : Similarity transformations are a subset of affine transformations.
  • Euclidean Transformations : Euclidean transformations are a subset of similarity transformations.
  • Isometry Transformation : Orientation preserving mappling
