This article explains how to enable the use of the WebGL graphics library by an internet browser. WebGL, English acronym for "Web Graphics Library" is a JavaScript API that allows you to render graphics in 2D and 3D using a compatible browser.
Steps
Method 1 of 3: Google Chrome
Step 1. Start Google Chrome by clicking on the icon
The latter is characterized by a red, yellow and green circle with a blue sphere in the center. Click on the Google Chrome icon in the Windows "Start" menu or in the Mac "Applications" folder to start the program.
Step 2. Type the chrome: // settings command in the address bar
The latter is located at the top of the browser window. A new tab will appear containing all the Google Chrome configuration settings.
Step 3. Scroll down the menu and click on the Advanced item
It is located at the bottom of the "Settings" menu.
Step 4. Make sure "Use hardware acceleration when available" is checked
It is listed in the "System" section visible at the bottom of the section reserved for advanced Chrome settings. The cursor on the right of the indicated item should be blue.
Step 5. Type the command chrome: // flags inside the address bar
The latter is located at the top of the browser window. This will bring up the list of experimental Chrome features that can be turned on or off as needed.
Step 6. Select the "Enable" option from the drop-down menu of the "WebGL 2.0 Compute" item
Scroll down the list to locate the "Webgl 2.0 Compute" feature. At this point click on the corresponding drop-down menu, located on the right, to select the option " Enabled".
If the "WebGL 2.0 Compute" item is not available, it means that the system drivers or graphics card installed in your computer may be in a list of incompatible or not to be used items. To circumvent this restriction select the " Enabled"from the drop-down menu under" Override software rendering list ", even if it is a configuration change that is not recommended to be made.
Step 7. Click on the Relaunch button
It is blue in color and located in the lower right corner of the window. Google Chrome will automatically restart and use of the WebGL API will be active.
Method 2 of 3: Firefox
Step 1. Launch Firefox
It features an icon of a blue globe and an orange fox. The Firefox icon is visible in the Windows "Start" menu or in the "Applications" folder on the Mac.
Step 2. Type the about: config command into the address bar
The latter is located at the top of the window.
Step 3. Click the Accept the risk and continue button
It is blue in color and placed in the center of the page. The first time you view the indicated page you will be warned that you are accessing a very important Firefox configuration page and that making mistakes could compromise the stability of the browser, its performance and data security. Click on the blue button to continue.
Step 4. Type webgl.disabled into the search bar
The latter is visible at the top of the page. The current status of the "webgl.disable" configuration parameter will be displayed.
Step 5. Double click on the webgl.disabled entry if the value "true" is present
If the value of the parameter in question is "true", double-click the corresponding name to set the value "false".
Step 6. Type the about: support command into the address bar
A summary page of some Firefox technical information will be displayed.
Step 7. Check the name of the graphics card listed under "Render WebGL Driver"
Both "Render WebGL Driver 1" and "Render WebGL 2 Driver" parameters are listed in the "Graphics" section of the page. If the name of a graphics card appears next to both of the entries, it means that the use of the WebGL library is active. Otherwise the graphics card in your computer may not be compatible
If the graphics card name is not displayed, you can solve the problem by opening the Firefox configuration page at this URL about: config, looking for the "webgl.force-enabled" parameter and setting it to "true". However, this is a configuration change that is not recommended to be made
