Which versions support AR (Augmented Reality)
On Android it's supported in this app: https://play.google.com/store/apps/details?id=org.geogebra.android.g3d but your phone/tablet needs to support the ARCore Library: https://play.google.com/store/apps/details?id=com.google.ar.core
You can check a list of supported devices here: https://developers.google.com/ar/discover/supported-devices
On iOS https://itunes.apple.com/us/app/geogebra-3d-graphing-calc/id1445871976 you need to have a device with iOS 11 that supports ARKit ie iPhone 6S / iPad 5 or later: https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/DeviceCompatibilityMatrix/DeviceCompatibilityMatrix.html
Problems with Classic 5 and macOS Big Sur
Sorry, it's a bug that's outside our control https://bugs.openjdk.java.net/browse/JDK-8256465
As a workaround you can set the System Preferences -> General -> Prefer Tab to "never" (or use one of the newer apps)
My computer crashed, where's my work?
If you were using GeoGebra Classic 5, have a look in the computer's temporary folder and look for the most recent file like GeoGebraUndoInfo6533063557894725659.ggb
Quickest way in Windows: http://www.tomshardware.co.uk/faq/id-2082907/temp-folder-windows.html
or just type this in Windows Explorer
%temp%
then Enter.
What's happened to offline export as a webpage?
If you upload your worksheet to https://www.geogebra.org/materials then you can download it as an "Offline Worksheet (.zip)" for example https://www.geogebra.org/material/show/id/RHYH3UQ8#download-popup
Graphical Glitches in GeoGebra Classic 5 (Windows)
These are due to a bug in the graphics card drivers. If you can't find newer or older driver that work then you can try
- setting compatibility mode to Windows XP (Service Pack 3)
- setting a
J2D_D3D
environment variable - run from the command-line with
-Dsun.java2d.d3d=false
See https://help.geogebra.org/topic/geogebra-on-windows-10-graphical-bug and https://wiki.geogebra.org/en/Reference:Command_Line_Arguments
