Mainly, three factors motivated me to start it:
- The existence of other spectacular virtual globes, like World Wind and Google Earth, (and others less spectacular like WW2D).
- Improve my knowledges about OpenGL, in concrete JOGL, basically to answer the questions: how works a virtual globe? and, how can I implement one?
- The knowledge of the existence of the NetBeans platform and the desire to learn to use it :)
