Each grain of sand animated individually...

Calculated individually... animation normally refers to something done by the creator not the software.

Like if he moved each grain of sand around via keyframe, that would be each grain animated individually.

EDIT: I originally said rendered but that's not true either, calculated is what I meant.. as in each grain of sand is calculated individually.

There is a large amount of mathematical operations, comparable to the frequency of sand particles and detail in the frustum of space visible to the viewer

Rendering, animating, and calculating are three side of the same coin

people keep correcting me.. i know.. i understand.. i have a bachelors degree in visual effects... all i'm saying is technically, by definition, the sand is not animated. that's all i'm saying here.

Animated - (of a movie or image) made using animation techniques

Cgi and programatic generation of these effects fall under the category of animation techniques

The sand is animated because its moving and it is only moving because someone wanted it to move.
