Folks,

Where do we find instructions of how to make a minimum install for Cesium, all the downloads seem to have example files and imagery that are not required.

Thanks

Ian

Hello Ian,

All the files included in the Build/Cesium folder (including files in the Assets, ThirdParty, Widgets and Workers directories) are used in some way by Cesium. Assets include images used to create the scene in the Textures folder, and data to compute transformations in the IAU2006\_XYS folder. The files in ThirdParty and Workers are used to draw primitives asynchronously, and the Widgets folder contains all CSS files needed to style the various widgets added when you create a new Cesium.Viewer.

Best,

Hannah

Yes, all files in the Build/Cesium folder are used in some way by Cesium.

OK thanks.  
So does that mean I can remove Apps, Source and Specs ?

Yes, you only need the contents of the Build/Cesium folder.
