2-DIMENSIONAL TRANSFORMATION
Modeling transformation is the mechanism to compose an image from modeling primitives. The modeling primitives are defined in their own coordinate system and then placed in the final scene by using geometric transformations. Using transformation, the whole image or only a part of the image can be changed.
