Ctional light per pixel)In this section, we will change the previous shader code to the direction light calculated by pixel. We need to split jobs by two shader to determine which operations need to be performed by pixel.First, let's look at the information received by each vertex:• Normal• Semi-Vector• Light Source DirectionWe need to transform the normal to the viewpoint space and then normalize it. We al
