2D Transformation and Viewingtopics include: 2d translation, rotation and scaling, matrix representations, 2d transformations and reflection, 2d viewing, window to viewport coordinate transformation, clipping operations, cohen-sutherland and liang barsky line clipping, sutherland-hodgeman polygon clipping, polygon clipping algorithms, curve, text and exterior clipping. 2D transformation is a process that modifies and repositions existing graphics in a two-dimensional space. It involves applying mathematical operations to the coordinates of points or vertices to achieve the desired... Show more
