Very cool, we look forward to anything you can share about the field test.
Cesium runs on iOS, for example, check out the Waterway Information for Vessels app from LSU.
Is it through Chrome on IOS?
Safari or Chrome will be similar since Chrome is basically a wrapper around Safari’s engine on iOS.
When running, does it support KML with network links? Will it support the various scene modes?
Yes and yes. Cesium has the same support for these on iOS as it does on desktop.
The most prominent limitation is iOS’s lack of support for the EXT_frag_depth WebGL extension, which creates limitations and artifacts for ground-clamped polygons. This will not be a problem in WebGL 2.
