An advanced WebGL debugging toolkit
About
WebGL Inspector is a tool inspired by gDEBugger and PIX with the goal of making the development of advanced WebGL applications easier. What Firebug and Developer Tools are to HTML/JS, WebGL Inspector is to WebGL.
Note: this is alpha software - if you find bugs, let me know (or better yet, fork and fix them! :)
Check out the readme on github for more information.
Status
There hasn't been an update in awhile, but the project is not dead! I'm currently working on a rewrite that enables a whole bunch of cool new features (plus a much better UI), however my new job at Google is eating up a lot of my time. v2 will go up when it's ready :)
Features
- Extension for injecting into pages
- Embed in an existing application with a single script include
- Capture entire GL frames
- Annotated call log with stepping/resource navigation and redundant call warnings
- Pixel history - see all draw calls that contributed to a pixel + blending information
- GL state display
- Resource browsers for textures, buffers, and programs
Live Demo
Click here to view a live demo (in a browser that supports WebGL, of course):
You can embed the inspector on your own pages like this if there is no extension for your browser or if you don't want to install it.
Install
ATTENTION: The extension is now hosted on the Chrome Web Store. If you have previously installed the extension you *must* remove and reinstall the Web Store version to get updates!
Chrome/Chromium extension (20+)
Browse to a page with WebGL content and click the 'GL' button that appears on the toolbar to embed the inspector.
