Among its other technological breakthroughs: advances in volumetric clouds, which filter and scatter light like the real thing, and water and dust effects.

Large ice crystals have fewer surfaces to scatter light, which helps to make the ice appear clear.

Cataracts form when these proteins become damaged and the cells make opaque clumps that scatter light.

Emulsions tend to have a cloudy appearance because the many phase interfaces scatter light as it passes through the emulsion.

And each interface, inhomogeneity or imperfection can deviate, reflect or scatter light, reproducing the above mechanism.
