At the moment, the main principles of working with 3D Globe in OpenWebGIS are following:
- 1. What you see on 2D map, you can see on 3D on the map when starting 3D map. But you can choose other base layers.
- 2. All changes and data editing, you can do only on 2D map. To see your changes on 3D map - click on the Update button over the globe.
- 3. You can set the automatic data update on the 3D map – to do it, check the checkbox "refresh" and set the refresh time in milliseconds, but keep in mind that this process can be very resource-intensive for your CPU, so think before you set the refresh time is very small.
The WebGL is disabled by default in Safari. Follow the instructions below to enable WebGL. The WebGL support in Safari is experimental. The 3D interactive visualization may or may not work well. Open the Safari menu and select Preferences.
• Click the Advanced tab in the Preferences window.
• Check the Show Develop menu in menu bar checkbox at the bottom of the window.
• Open the Develop menu in the menu bar and select Enable WebGL.
I am using mobile phone / tablet.
The 3D interactive visualization may or may not work on a mobile device. It could work in Chrome on Android and Windows 8 devices. But it also depends on the model of your mobile device.
My computer is very old.
The grahpic card of your computer must support WebGL to make The 3D interactive visualization work. Almost all video cards from NVIDIA and AMD since 2004 support WebGL. Recent Intel video cards also work well. If the 3D interactive visualization does not work in Chrome on your desktop computer, you maybe consider using another computer instead."
