• WebGPU/glTF case study

  • #gltf
  • #webgpu

  Over the last year or so I've been working on Chrome's implementation of the new WebGPU API, a successor to WebGL based on more modern graphics API patterns. While working on the API I've also been busy building a lot of demos and other community resources with it, and one topic has been brought up by people I've talked to probably more than anything else: How do you keep the API state manageable when loading something like a glTF model?So I wrote about it!If you're interested in WebGPU, glTF, o

• Early access to the WebXR Device API in Chrome Canary

  Hey, are you a web developer that wants to play with bleeding-edge browser VR APIs and influence their development? If so read on! The WebXR Device API is the next iteration of WebVR, and the API that we intend to release in stable browsers at some point and support going forward. It’s still a work in progress, but the first (mostly) working implementation is now available in Chrome Canary for Android and Windows behind a flag, and so it’s the perfect time for motivated developers to start playi

• New experimental WebVR builds for Android

  It's an exciting time for WebVR on mobile right now! Today the Chrome team announced that WebVR is available as an Origin Trial in the Chrome 56 Beta for Android. Oculus has also recently launched their Carmel browser preview, and Samsung is continuing to improve their implementation. On the desktop side Mozilla is continuing to make great progress, and the spec is making huge strides as all of the interested parties (like Microsoft, whose input has been invaluable!) identify the rough points an

  (This post was originally sent to the public-webvr mailing list, which you should totally follow if you're interested in the latest and greatest WebVR news!) Hello WebVR community! The Chrome team has been a little quiet on the WebVR front recently, and I apologize for that and thank you for your patience.

  By virtue of the WebVR work I've been doing I've been lucky enough to have a fair amount of access to VR hardware, and at this point feel like I've got a pretty good handle on where each of the newly released devices stand in relation to one another. Since it seems to be a popular topic lately I figured I'd give a brief overview of my thoughts on the Vive and Rift. To start with, they're both fantastic devices.

  Consumer VR is at our doorsteps, and it’s sparking the imagination of developers and content creators everywhere. As such it’s no surprise that interest in WebVR is booming. Publications like the LA Times have used WebVR to explore the landscape of Mars, and a doctor was able to save the life of a little girl by taking advantage of Sketchfab’s VR features.

And not some silly small asteroids game or anything like that. No! I wanted to build Shooters and Platformers and RPGs. The epic kind!

  It's taken me several days to get over my knee-jerk, emotional, Vader-esque "NOOOOO!!!" response regarding Facebook's purchase of Oculus. I wrote up a "Please cancel my DK2 pr-order" email immediately after hearing the news, but resisted hitting the send button because I knew that anything I did at that point would be out of spite and not because I truly no longer believed in the product. Now that I've had some time to think on the matter, though, I feel like I can actually enumerate my concerns

• Xbox One controller in Chrome on OSX

  I've been working lately on better Gamepad API support in Chrome (call it my "20% project"). It's been a fun change of pace from WebGL, primarily because it's much more straightforward code. In the process of learning the ropes, I decided to try something a little crazy: I noticed that our code path for supporting the 360 controller on OSX didn't rely on any drivers, but instead used IOKit to parse the data packets manually. (Check out that code here.) So I figured, hey! Why not try the same thi

• How Blink has affected WebGL, Part 2

  In a previous post I detailed some of the ways that the migration to Blink has affected the WebGL pipeline. The short version is that we were able to remove some layers of abstraction without changing the code which was executed, which cleaned up our dependency diagram a bit. At the time we ended up with a data flow that looked roughly like this: That was 8 months ago, and I've been busy in the mean time! So let's take a quick peek at the current state of affairs.

• Notch, WebGL, Dart, and ramping up quickly

  Just a little something I thought was worth pointing out. @notch, the creator of Minecraft, has been posting updates on his latest toy project to his Twitter account recently. I've found this very interesting because he's doing a WebGL app in Dart, which just makes me all sorts of happy. Ignoring that, however his tweets illustrate something that I feel is very important.

• failIfMajorPerformanceCaveat: With great blacklisting power comes the need for self restraint

  Chrome is gaining a new WebGL context creation attribute: failIfMajorPerformanceCaveat. In the words of the spec, when you've set this useful little boolean to true: Context creation will fail if the implementation determines that the performance of the created WebGL context would be dramatically lower than that of a native application making equivalent OpenGL calls. Essentially, if there's any reason why the browser feels that the requested WebGL context will have significant performance overhe

• Using WebGL on Chrome (AKA: "Why don't I have the WebGLs?!?")

  It occurred to me the other day that although WebGL is now available on more devices with Chrome than ever before, Google actually hasn't said a whole lot about who has it, how to get it, and what to look for if you don't have it. Today I'm going to try and fix that! The TL;DR version is that with some predictable exceptions most devices that run Chrome can get to WebGL at this point, and an increasing number of them have it turned on without any action on the part of the user.

• At last! Chrome D3D11 day has come!

  As of revision 223716, Chrome Canary will have the ability to use Direct3D 11 (via ANGLE) as the rendering backend! Woot woot! The new backend can be enabled using the "Enable D3D11" flag in about:flags. To tell which backend you are using visit about:gpu and look for the GL_RENDERER string. That's cool, but should have no impact whatsoever on your day to day Chrome use (and if it does, we want to hear about it!) So why do I bring it up?

• What's coming in WebGL 2.0

  The WebGL working group has just released a public draft of the WebGL 2.0 spec. Hooray! Of course, being a public draft things are still subject to change and there are still plenty of TODOs, so don't be too surprised if things get chopped, tweaked, added or completely reworked before WebGL 2.0 reaches a browser near you. The nice thing is, however, that since the entire goal of the spec is to bring OpenGL ES 3.0 capabilities to the browser the chances of things deviating too much from that spec

  Let's play a quick game: I'm going to describe a relatively recently announced web technology, and I want you to guess what it is. It was developed by a generally well respected company that focuses on moving the web forward. It was started to enable the web to move beyond the inherent limitations of javascript. It allows developers to run applications programmed in a language other than javascript. The company behind it encouraged others to join in its development, and has actively been improvi

• WebGL Draft Extensions in Chrome

  I mentioned this was coming in my last post, but it's a significant enough change that it's worth addressing on it's own. New Chrome builds, starting with today's Canary build, will begin including a new option in about:flags called "Enable WebGL draft extensions" (This can also be activated via the command line with the --enable-webgl-draft-extensions flag) When you enable this it will allow WebGL to access extensions that Chrome has implemented but are still in draft status on the WebGL Extens

• How Blink has affected WebGL?

  One of the topics that was suggested when I recently took a poll on Twitter/G+ of potential blogging topics was what kind of impact the switch to Blink has had on Chrome's WebGL implementation. I thought this would be a great area to talk about, because it allows me to dig into the guts of how WebGL works a bit more than most of you are used to. If you're not familiar with the situation already, Chrome recently switched rendering engines from WebKit to Blink, which is based off the WebKit source

• How Microsoft could possibly, just maybe, become WebGL's biggest supporter

  Ready to jump head-first into wild speculation land? Come on, it'll be fun! It occurred to me today that there's a slim possibility that in the near future Microsoft may actually become the biggest driver of WebGL adoption in the industry. Yes, that's right, "WebGL considered harmful" Microsoft. Sounds crazy (probably is crazy) but I feel the possibility is definitely non-zero. Why?

• Recommended reading - Debugging a Resource Leak in WebKit

  My colleague at Google, Ken Russell, has just posted a very in-depth recounting of how he tracked down a fairly tricky WebGL bug in Chrome's WebKit port after I had identified that creation of Web Workers was causing WebGL resources (and a lot of other resources too!) to leak.

• The WebGL Guide to reading OpenGL shaders, Part 1

  When discussing graphical techniques in WebGL, it's not uncommon to hear people say "Here's some shader code from an OpenGL desktop app! Use that!" And for the most part that's an entirely reasonable thing to say. Typically it's only when you start looking at OpenGL 3+ (DirectX 10+) level hardware and applications do we run into things that are simply out of reach of WebGL as it stands today. There are, however, some oddities from the desktop relm that have (wisely) been excised from OpenGL ES 2

• WebGL JS1K entry

  As a sort of follow up to last years Itty Bitty WebGL post I decided to take a crack at actually entering the js1k competition this time around. Since the theme of the competition is "Love" I thought it would be fitting to do a minimalistic version of this awesome little "beating heart" shader. You can see my under 1k version here. And the not-quite-so-compressed-but-still-really-hard-to-read source code here: c=document.getElementById('c'); c.height=300; g=c.getContext('experimental-webgl'); b=

• Protecting WebGL content (and why you probably shouldn't)

  I received an email this morning from a developer that is in a predicament that I think many WebGL developers will find themselves in pretty soon: Do you have any experience with protecting assets in WebGL? I wrote a quick solution to protect textures during transfer - base64 encoding + concat server side and splitting + creating imgs client side. Still, using WebGL Inspector I can get all textures transferred to the graphics card. I wonder if you have any ideas on how to prevent that. I don't m

• Compressed Textures in WebGL

  [UPDATE: The compressed textures spec has been changing, and so the original code posted with this entry stopped running. I've since fixed the code and updated the information below. Be aware, though, that the spec may STILL be tweaked at some point!] I gave a presentation this last Friday at WebGL Camp 4, the slides of which are online now. I had a great time, met some awesome developers, and saw a lot of things that got me really excited about the future of WebGL. I highly encourage anyone tha

• Building the Game: Part 5 - Static Level Geometry

  See the code for this post, or all posts in this series. See the live demo. (WARNING! The live demo for this post will probably take a while to load and will most likely not run at 60 FPS! Optimizations will come in later posts.) Sorry about the long gap in posts, but this has proven to be one of the more challenging things I've attempted so far. That's primarily been because I wasn't too familiar with how Unity handled things behind the scenes until I started working on this particular post. I'
