-        Possible interactions between the volume and the light traveling through the medium. In this example, it first loses $\sigma_a L(x, \omega)$ radiance due to the material absorbing a portion of the light, then loses further $\sigma_s L(x, \omega)$ due to out-scattering. Then it gains $\sigma_s L_i(x, \omega)$ radiance from light scattered at another part of the volume. Lastly, it gains $\sigma_a L_e(x, \omega)$ light due to the material's emission.
