algorithm - Render local DEM on NASA world wind -


i trying render local elevation data on world wind. , use world wind's tessellation algorithm tessellate data , render on globe. know localelevationmodel. , able store dem file using this:

    localelevationmodel localelevationmodel = new localelevationmodel();     string filepath = "";     localelevationmodel.addelevations(filepath);

i can access model using lookupelevation method on max,min lat log localelevation data. don't know how proceed forward. have looked rectangulartessellator class couldn't understand how use it. clues on how can this?

ps:i looking @ source code couldn't understand make scene out of it. wanted know more it.

pps: if not possible can guide me easy implement , optimized algorithm rendering of terrain. supports various lods of generated mess.

thanks,
