"We've removed painting from the bottleneck in Servo" More info about WebRender: https://github.com/servo/webrender/wiki https://github.com/servo/webrender/wiki If you want try it at home, you "just" need to build servo: http://github.com/servo/servo http://github.com/servo/servo (git clone, then ./mach build -r) and run servo with webrender: ./mach run -r -- -w http://wikipedia.org http://wikipedia.org (edit: removed the bit about chrome's gpu rasterization - see pcwalton's comment below)

Re the building, if you're on mac with homebrew, it should be as easy as: brew install --HEAD servo/servo/servo and servo -w http://wikipedia.org http://wikipedia.org Keep in mind though, servo has a long way to go.

  Is it a compiled bottle? I remember last time trying Rust I had to wait maybe half an ahour to compile everything. I think it was the time when servo was compiling their own version of Rust :)

    Servo now downloads a Rust snapshot. But you still have to compile everything else needed to build Servo.

  What about for using it as a headless browser with javascript and Rust manipulation of the DOM? We have a http proxy that would like to analyze html responses and rewrite parts of the page. Is servo ready for that or should we use something like PhantomJS? Thanks!

    Side note if this is something you're interested in doing, you might want to check out the FastBoot project from the Ember camp. It's built on top of non-Ember-specific libraries that let you do server-side DOM manipulation without needing something like PhantomJS, just node.

    I'm not involved with the project...just an admirer. I do know that it has a headless option in the command line invocation.

Chrome's approach is fundamentally different: it's the main difference I was describing at the beginning of the talk, by contrasting Chrome's immediate mode approach with WebRender's retained mode. (By the way, Safari, IE 9 and up, and Firefox on Vista and up all use immediate mode GPU painting backends like Chrome does.) Incidentally, I don't deserve the lion's share of the credit here. Veteran game developer Glenn Watson is really the brains behind the project—my role has mostly consisted of picking off a few scattered features and optimizations to implement.

  Great work guys. Will help push the web forward! Vulkan/Android coming anytime soon?
  - pcwalton 11y ago
    Android is working already. As for Vulkan, I answer that at the end of the talk, but the basic story is that we're Vulkan-ready architecturally, but nobody has done the port yet.
    - dharma1 11y ago
      Awesome. What's the perf like on Android? Is there an apk to try?
- vanderZwan 11y ago
  Have you been able to make use of hardware accelerated path rendering? Like the stuff Mark Kilgard is working on? (I mean, "painting on the GPU" doesn't say how you use the GPU, and I've been wondering if there's anything new happening in path rendering land after seeing a video on Kilgard's work years ago)
  - pcwalton 11y ago
    We actually aren't doing any path rendering yet; CSS as used on the Web is all boxes and triangles, aside from glyphs. One of the neat things about WebRender is the observation that triangles are pretty much all you need for CSS. A future extension to support SVG and glyphs on the GPU would be pretty interesting though!
