$\vec n = \frac{\vec \nabla P }{\left \| \vec \nabla P \right \|}$

$n 2 * sinΘ t = n 1 * sinΘ I$

${I_{1}\over I_{0} } = e^{\epsilon l c}$

${I_{1}\over I_{0} } = {absorption}^{l}$

$\vec n_{near} \ = \cos (\rho). \vec x + \sin (\rho). \vec y$

$\vec n_{left} \ = \sin{(\rho + fov)}. \vec x\ - \cos{(\rho + fov)}. \vec y$

$\vec n_{right} \ = -\sin{(\rho - fov)}. \vec x\ + \cos{(\rho - fov)}. \vec y$

$w s u n = p o w (cos(Θ v i e w - s u n a n g l e), p o w e r)$

$c s k y t e m p = w s u n * c w h i t e + (1 - w s u n) * c b l u e 1$

$w s a t = m i n (m a x (ρ v i e w / ρ g r a d i e n t,0),1)$

$c s k y = (w s a t) * c s k y t e m p + (1 - w s a t) * c b l u e 2$
