goals[edit | edit source]

  • to be as simple as possible to allow simulation in browser (javascript)
  • water masses should be simulated, relief, in future other substances: rocks, electrofields will be simulated similarly

Societies simulation[edit | edit source]

server should give[edit | edit source]

we may say that wikipedia:Geoid is simulated

grids variants[edit | edit source]

let's start with with k=7(Npix=196608) or 8(Npix=786432 and is heavy for GPU) that corresponds to 1 or 2 of aw:zoom levels and later with

k=8 (Npix=786432) that corresponds to 2, 1024x1024 pixels
k=9 (Npix=3145728) that corresponds to 3 and to Earth2014#5 arc-min
k=11 (Npix=50milion) that corresponds to 5 and to Earth2014#1 arc-min

cells are fixed[edit | edit source]

water is moved not coordinates, however after Earch axis shift coordinates may be shifted too + the whole world ocean is covered easily

cells may be moved[edit | edit source]

obsolete

like in aw:SPH techniques

  • spheres

- complex calculations of depths, not needed during coastlines calculations

  • cylinders or cones with top in the Earth center

+ swirls may be modeled

physics[edit | edit source]

requirements:[edit | edit source]

1 version[edit | edit source]

  • Earth is the single solid and the single crystal
  • gravitational interaction is simulated but not electromagnetic
  • water velocity (friction and viscosity) is ignored

algorithm[edit | edit source]

contouring

done[edit | edit source]

  • start
  1. loop through all relief, form basins
  2. check forces at basins borders - must be 0
mean relief data
  • axis change influences
  1. on geoidNormal
  2. calculate how water should be reassigned between basins
  3. reassign water
  4. not done: calculate some contour and go to 2.
  • export-import
  1. initial conditions: geiod, relief accuracy
  2. algorithms run
  3. resulted basins grouped by K
  • eddy visualization

basin has properties

direction 
volume in/out shown by start thickness 
volumeOnDirection shown by length
