Introduction of Polygon Rendering and Ray Tracing Method
Different type of sources of light and the reflections generated by the object in exposure of these sources. As an object is exposed to light different phenomena arise as reflection, refraction, and so on. Out of them shading is most significant as similar helps in achieving the realism in computer graphics. We have also discussed the idea of polygon rendering, and ray tracing that are helpful in achieving photo realism of a 3-D scene.
De Casteljeau algorithm: The control points P 0 , P 1 , P 2 and P 3 are combined with line segments termed as 'control polygon', even if they are not actually a polygon although

Assumptions for Area Subdivision Method a) ¾ Plane of projection is z=0 plane b) ¾ Orthographic parallel projections c) ¾ Direction of projection as d= (0,0,-1) d
Problems at Shared Vertices - Modeling and Rendering Shading discontinuities can arise while two adjacent polygons fail to share a vertex which lies along their common edge.
What is Aspect ratio? The ratio of vertical points to the horizontal points essential to produce length of lines in both directions of the screen is known as the Aspect ratio.
