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]
- relief polylines by aw:isolines
- simulated water level polylines
- Geojson to be displayed in aw:Category:Georender
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
- !HEALPix#grid cells
- squares or rectangles like in aw:Isolines#QuadTree
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]
- for simplicity compressibility, temperature, salinity are ignored
- from conservation laws only Conservation of rest mass is guaranteed, wikipedia:Conservation of linear momentum, wikipedia:Conservation of angular momentum are restricted
- we may use wikipedia:Conservation of energy law with concepts like potential and kinetic energy but it will be harder to achieve accuracy
- world (water and solid) is presented by basins of different sizes; basins cannot penetrate each other
- every basin has coordinates and mass
- collisions should be detected
- fundamental interactions between basins should be simulated as gravitational and electromagnetic
- aw:gravity is calculated from basins to the Earth center
- centrifugal force from Earth rotation axis is calculated
- for optimization there is Basins grouping that forms "Areas" (group of basin that has closed contour)
- accuracy and precision should be controlled
- accuracy of centrifugal force depends on basin size
- solid forms crystals but water cannot form crystals
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]
done[edit | edit source]
- start
- loop through all relief, form basins
- check forces at basins borders - must be 0
- Meridional approximation
- mean relief data
- axis change influences
- on geoidNormal
- calculate how water should be reassigned between basins
- reassign water
- not done: calculate some contour and go to 2.
- export-import
- initial conditions: geiod, relief accuracy
- algorithms run
- resulted basins grouped by K
- eddy visualization
basin has properties
