In OpenWebGIS users can create not only a flat map (2D), but also 3D maps. To do this, OpenWebGIS uses Cesium JavaScript library. The article "3D maps, new version of Cesium JavaScript library and OpenWebGIS" tells about this in detail. On the first of February 2016 the new Cesium Version 1.18 was released:
"Here are the highlights of the new release:
- Reduced the amount of CPU memory used by terrain by ~25% in Chrome.
- Added a Sandcastle example to “star burst” overlapping billboards and labels.
- Added VRButton which is a simple, single-button widget that toggles VR mode. Cardboard for mobile is supported. More VR devices will be supported when the WebVR API is more stable.
For more details and the full list of changes, see the changelog.”
To improve the efficiency of work with maps for users of OpenWebGIS the decision was made to migrate to this new version of Cesium. A lot of work has been done to correct the source code for the new version of Cesium and besides several problems were fixed that the users previously encountered while visualizing 3D maps.
