Computer graphics learning notes two dimensional geometric transformation

The operation applied to the geometric description of an object and changing its position, direction or size is called geometric transformation. Geometric transformations are sometimes referred to as modeling transformations. Modeling transformation is generally used to construct scenes or give hierarchical descriptions of complex objects comp ...
