The Liang-Barsky Line Clipping Algorithm is a parametric line-clipping method that efficiently determines which portion of a given line segment is inside a rectangular clip window. The algorithm uses parametric equations and conditions to clip lines based on edge normals. --- ### Given Data We have a rectangle PQRS with coordinates: - P(2,3) - Q(6,3) - R(6,4) - S(2,4) The clipping window is defined by its opposite corners at (1,0) and (4,6). ### Step 1: Define the Clip Window Bounds The clip window is given by: - \( x_{\text{min}} = 1 \), \( x_{\text{max}} = 4 \) - \( y_{\text{min}} = 0 \), \( y_{\text{max}} = 6 \) Each edge of the window has a normal and an inequality condition: __________ _______ _____ _______ ________ ________ _______ ______ ____ ______ ______ _______.
