Advice about simple way, or plugin, to animate flowing particles representing stylized large scale geological processes (erosion).
In short, I would like to make an animation to illustrate an aspect of erosion of the ground, including soft soil, sediment rock and bedrock as well as mountain formations, and comparisons between those).
The animation is not meant to be a very detailed simulation with exact natural parameters, suffice to illustrate amounts of (natural rates) erosion over longer periods of time. Think like low confines of grains slowly grinding down the initial mass while spreading out filling up some lower areas around it, etc.
The animation doesn’t have to illustrate actual natural looking geological or geographical features, it’s more important to just grinding down and lover the level of particles spreading it out, and then perhaps lift up the eroded material again and start over eroding it again back an fourth aso.
So what I’m asking for is a convenient way, or suitable plugin, to represent the movement of eroded particles the particles where I can mess around with heaps of particles back and fourth. Stylized large scale geological processes meant to illustrate displacement of volumes over time, which is why true representation of geology or geography is less important in this case. If possible to make it cool looking while at it, isn’t a bad thing, though.
