Cohen Sutherland algorithm
Point clipping is very simple. All you need to check is whether a point is inside the window extremes in x- and y-directions. For line clipping several algorithms have been introduced over the years and many refinements have also been suggested by people in order to improve the performance of the algorithms. One of the first algorithms that is still being used in applications is Cohen Sutherland algorithm.
Define clipping and covering (exterior clipping)? Clipping is the process of cutting a graphics display to neatly fit a predefined graphics region or the view port. This is
Consider the line segment AB in 3-Dimentional parallel to the z-axis along with end points A (- 5,4,2) and also B (5,-6,18). Carry out a perspective projection upon the X=0 plane;
Scenes - polygon rendering and ray tracing methods In the context of ray tracing, a scene is a set of objects and light sources which will be viewed through a camera. All of

Raster and Random Scan Display Technologies For display or printing graphics objects, various technologies have been invented. Research and development is still on for getting
De Casteljau Algorithm For computation of Bézier curves an iterative algorithm known as de Casteljau algorithm is used. The algorithm uses repeated linear interpolation.
Background Texturing is like wallpapering; you are pasting an image onto the OpenGL Quad primitive. Recall that GL_QUAD is specified by four vertices. An image, or a texture,
