Lighting in computer graphics refers to the placement of lights in a scene to achieve some desired effect.. Lighting is very important part of an image synthesis.. It is used to create 3D effect by separating foreground from background.. You will be able to demonstrate consistent layering of pencil crayon and value changes with this exercise.. Ribbon Shading.
