webgl-diagnostic is a WebGL onboarding system to help users get a working WebGL implementation and, should an error occur, supply helpful system information to you in a bug report. The software is free and open source under the MIT Expat license which can be found in the LICENSE file.
- Up-to-date and accurate browser and platform detection (cf. get.webgl.org)
- Easy system profile report generation for high quality user bug reports
- A user support database in JSON with support for experimental implementations and plugins
- Plugin recommendations (e.g. Google Chrome Frame for IE users)
- WebGL extension detection
- Graphics driver detection and driver support links
- Easily skinnable support messages
- Easily localizable support messages
- WebGL capability sniffing
- Your contributions
You will need an XSLT 1.0 processor (e.g. xsltproc from libxml/libxslt) and a make program (e.g. GNU Make) to build localized HTML versions of the onboarder. If you have tools like these, you can run 'make' in example/ to generate example localizations.
Onboarding messages are provided in an ad-hoc XML dialect in lang/ organized by HTTP language code (ISO 639-1). A simple language resource processor is provided as lang/message.xsl.
Driver information is presently gleaned from the RENDERER string on a WebGL context unless the user is on Mac OS X, in which case the driver vendor is reported as "Apple".
The get.webgl.org/ directory contains the scripts that the author uses to stay up-to-date on changes to this onboarding site. These scripts make If-Modified-Since requests using curl to reduce the burden on the get.webgl.org host. Users of this software should monitor this repository or the get.webgl.org site directly to stay current on ecosystem changes and prevent bit-rot.
If this monitoring and maintenance is not possible or desirable, we recommend linking users to get.webgl.org.
The ext_reg/ directory contains the scripts that the author uses to stay up-to-date on new WebGL extensions. These scripts make If-Modified-Since requests using curl to reduce the burden on the Khronos host.
