COMPUTER GRAPHICS - Implement Sutherland Hodgeman polygon clipping algorithm.
Experiment No.07 A.1 Aim: Implement Sutherland Hodgeman polygon clipping algorithm. A.2 Prerequisite: 1. C Language. 2. Geometric Concepts. 3. Concept of 2D basic Transformations. 4. Clipping Concepts. A.3 Outcome: After successful completion of this experiment students will be able to, Apply the transformations and clipping algorithms on graphical objects. A.4 Theory: The Sutherland-Hodgman algorithm clips a polygon against all edges of the clipping region in turn. The Sutherland - Hodgman algorithm performs a clipping of a polygon against each window edge in turn. It accepts an ordered sequence of verices v1, v2, v3, ..., vn and puts out a set of vertices defining the clipped polygon. This figure represents a polygon (the large, solid, upward pointing arrow) before clipping has occurred. The following figures show how this algorithm works at each edge, clipping the polygon. Clipping against the left si...
