+==== Notes on WebGL ====
+The technology required to display 3D scenes is WebGL2. This is supported from the following browser versions:
+  * Chrome from version 56
+  * Firefox from version 51
+  * Safari from version 15
+  * Edge from version 79
+  * Meta Quest Browser from Quest 1
+For Android devices, at least the following browser version must be available
+  * Chrome from version 124
+  * Firefox from version 125
+  * Samsung from version 7.2
+Source: https://caniuse.com/?search=webgl2
+If WebGL2 is not available, this message appears:
+//The configurator cannot be displayed without WebGL2 support. Please update the graphics card drivers and try again. You can find details about your device at [[https://webglreport.com/?v=2|WebGL2 Report]]//
+WebGL 2 support may be disabled when using a Firefox browser. Therefore, check this in Firefox:
+  - Enter ''about:config'' in the URL line
+  - Confirm that you want to edit the settings
+  - Filter for ''webgl2''
+  - Set the value ''webgl.enable-webgl2'' to ''true''
+{{:pasted:20240527-084451.png}}
+Also check the value ''webgl.disabled''. Here ''false'' is the correct value.
