cos^4 for 5D integral of calculating the radiant intensity. depending on the distance between the lens hole and the plane. the degree to the pixel area, area of the lens, area of the pixel, and time.

I don't quite understand what the 5D integral is for. I understand the formula itself and the math we are doing but, I am wondering more of why. Why exactly do we need a 5D integral for the instance of the hummingbird picture? And what would we lose in that image if we took only a 3D integral?
