Randomly placed points and AnalyticSurface

[Autar]

Hello everyone,


I'm new to Worldwind, and new to GIS in general.

I've been tinkering with Worldwind for a few days now and I'm facing a problem. I want to display data. I have a collection of points (lat, lon, value) and I'd like to show a colored surface, like in AnalyticSufaceDemo (I don't need animation and 3D, a static 2D map is fine). I don't understand everything involved in the demo but it seems my problem comes from my points not being evenly placed.

As far as I know I need a grid of points to generate the AnalyticSurface. What I'd like to know is : Do I understand this right ? Does Worldwind provide tools to generate a grid of smoothed values from randomly located values ? If not, what are the general steps to take in order to get these values ?

Thanks :)
