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.
Polygon -Rendering Methods Now we will see the application of an illumination model to execute the rendering of standard graphics objects that are formed along with polygonal
