It is a simplified way of formulating phong's illumination model.

It is denoted by H.

It is called halfway coz it's direction is halfway between the directions of the light source and the viewer.

For a given light source and viewer positions, vector H gives the orientation direction for the surface that would produce maximum specular reflection in the viewing direction.

Thus H is also called the surface orientation direction for maximum highlights.
