Modifiers That Affect Surface Rendering

Rendering is the process by which a 3D program draws an image of a 3D scene. There are a number of variables to take into account: the point of view; the system of projection; the position of objects; lighting; object properties such as color and visibility; the mode of display; and so on.

To speed up rendering, 3ds max shades only the outside surfaces of objects unless you set it to do otherwise. This means that each face is shaded only on one side—the side that the surface normal projects from. By comparing the angle of a normal to the source of light, the program determines how much intensity, or brightness, of light it should use to render each individual face (Figure 6.64).
