I am not that familiar with the js language and any js project.
But I'm now quite interested in the Cesium.
Thus I want to fork one in the github.com and make some modification on it to get own thoughts working.
However, I have been trying to trace the process of the terrian(from downloading to displaying) for a few days; to my regret, i get no door to get in.
So, I am posting to look for some help or some suggestions,
about: 1) how should i get a clue to trace into the system or where should i start
2) any recommendations about reading js project
