Need some sandworms and then you got Dune :)

the funny thing about sand simulation is that you need more particles then in a watersimulation to get a realistic enough result. And in the real world its the other way around... :D

Good job. Just an idea to speed it up: it would seem that the particles in regions of high and homogeneous density do little, whereas the 'edge' particles at lower density *do* move. So maybe divide your system up into cells, compute the average density per cell, and then only simulate the particles in cells of lower density. (N.B. Rather than recompute the density on each iteration, pre-compute it and then keep track of changes in the density as the particles move.)

@Capeau bear in mind that in those videos, only water is simulated, not air. It behaves like water in a vacuum tube.
-
yes but not that extreme
-
@Capeau well, water bounces when hitting a surface with a certain kinetic energy. Did you ever watch sea waves hitting a wall? It behaves just like that.
-
not really.. that must be the most bouncy/rubbery water ever lol
-
@Capeau until you see vimeo dot com/17629485 and redefine your standards of realistic water simulation ;)
-
it could be used to train neural networks for earth moving machinery.you reaally should think about this...we'are talking autonomous construction machines turning deserts into cities here.

how exactly do you change the amount of particles anyway?

Would make a great destructible level for games like Scorched Tanks!
Nice work.

i'm working on something along those ideas gameplay wise, but it was going to be about ships, with particle based water and deformable/destructible ships.

Is it real-time?
Kethors 2 years ago
well, there are differing views on what is real-time, but i'll just say, this video is playing at the same speed it was recorded and is not sped up.
