java - Interpolating irregularly located data to -


i trying display colored surface in worlwind java, colors depend on latitude/longitude located values (e.g temperature) set of irregularly located data. i'm using example found in gov.nasa.worldwindx.examples.analytics package. there class interpolator2d there doesn't seem able compute irregularly located data.

as far know i'm missing 1 thing in order : way generate grid of regularly placed points set of randomly located points. far don't have way that.

putting aside wwj stuff, need way generate interpolated (and maybe extrapolated) grid of values set of arbitrary located values.

any idea, code, api or algorithm welcome. doesn't matter if solution not working in lat/lon coordinates, arbitrary coordinates fine.

ps : want in java : https://stackoverflow.com/a/3867302/1435322

thanks.
