I am trying to display a colored surface in Worlwind Java, where the colors depend on latitude/longitude located values (e.g temperature) from a set of irregularly located data. I'm using the example found in the gov.nasa.worldwindx.examples.analytics package. There is a class Interpolator2D there but it doesn't seem to be able to compute irregularly located data.
As far as I know I'm missing only one thing in order to do that : a way to generate a grid of regularly placed points from a set of randomly located points. So far I don't have a way to do that.
Putting aside all the WWJ stuff, what I need is a way to generate a interpolated (and maybe extrapolated) grid of values from a set of arbitrary located values.
Any idea, code, API or algorithm is welcome. It doesn't matter if the solution is not working in lat/lon coordinates, arbitrary coordinates are fine.
PS : Basically what I want is to do this in java : https://stackoverflow.com/a/3867302/1435322
