I am working on a project that shows geospatial data using worldwind Java library. We are currently working of the generation of PNG images that displays different locations.
As worlwind relies on JOGL underneath for rensdering its contents, I wirte you to ask for a way of exporting displayed data to PNG. Furthermore, if PNG generation can be done headlessly without the need of displaying the GLJPanel.
We have triaed several way but we only get black images after all.
