This item in japanese. Jul 09, 8 min read. Bruno Couriol. Gabriel Cuvilliersenior software engineer at Continuation Labs, ported the iconic Doom 3 game to browsers with WebAssembly. The 7-week full-time effort illustrated both the present performance potential and the missing parts for WebAssembly today to seamlessly run heavy-weight desktop applications and games. InfoQ interviewed Cuvillier on the technical challenges encounteredand the lessons to be learnt for developers thinking about porting desktop applications with WebAssembly.
Doom 3 is a horror first-person shooter video game originally released for Microsoft Windows in But, in practical terms, apart from some small nice benchmarks and sample demonstrations, there have been very few real-world use cases publicly studied and shown. So, in order to convince myself that WebAssembly could fulfill its promises, I decided to move things to the next level and port a real program. So, by the end ofI decided to port Doom 3 to the Web, and ultimately convinced myself that WebAssembly is a technology to seriously consider for the next 10 years.
InfoQ: You mentioned that D3 is a very demanding game to run in a browser. What makes it so? What are the performance drivers which are present in native desktop operating systems and missing today in desktop browsers? Concerning 1as I said in the previous answer, it is a very demanding game by itself because it provides a good graphics quality level, while running on a single thread of execution.
This means that the amount of things needed to be computed sequentially while trying to stay at 16ms per frame is simply massive: unified lighting model with dynamic per-pixel lighting and real time shadows, skeletal animation, rigid body physics, AI, networking, and so on. So, when the Wasm code calls a graphic API, this will not directly call your graphic card driver as it is used to on a native build.
And all of this introduced a lot of overhead in the end. InfoQ: Are you aware of other desktop games which have been ported to the browser with WebAssembly? Is the performance profile similar to the one you achieved with DOOM3? There are some nice tech demos, but no full AAA games. But - shameless plug - another nice game porting experiment of a full commercial video game is simply the previous game I ported to WebAssembly: Arx Fatalis. This is a video game, so quite a bit uglier than D3, but nevertheless very interesting.
It worked nicely, but after Google decided to deprecate the technology in favor of WebAssembly, I decided to migrate the port to WebAssembly as well as a way to learn the new technology. Honestly, that hurts. I used them a bit in the Doom3 port to ease up the porting process. Though is is not related to WebAssembly, but more to the browser implementations that are not yet all implementing this feature Safari in particular. InfoQ: You spent weeks working full-time on the port, and described the task as fairly complex.
In your opinion, should developers start experimenting with porting major applications to the browser, or is it wiser to wait for the technology to mature? I am currently working on a long-term project to illustrate usage of WebAssembly in 3D CAD software, and I recently did some contractual work on an upcoming product related to the last example mentioned.
Additionally, the people working on WebAssembly ecosystem - be it on the compilers, Wasm runtimes or compilation environments - are very skilled in their respective field. This last point may explain why it is still difficult to have an up-to-date in-depth book about the platform. Join a community of oversenior developers. View an example.

Why not Sponsor me via GitHub! This also involved updating to a newer xtensa-espelf-gccvia the weird installer script. I mostly worked from the linux and zephyr WAMR platforms and tried to work out what was needed as I went along …. As always, I spent a maddening amount of time running in circles before finding something which worked well enough: well, it compiles and I can always clean it up later.
One very good hint I got along the way thanks Jimmo is to quarantine CMake off into its own build directory by doing something like. More on those later. But really understanding how this platform works requires a lot more! So the next step is to work out how to compile my own code and pass it to WAMR for execution. This is where WASM gets a little … confusing. Much of the point of this little effort was to get JIT working, and it turns out that that might be harder than I thought.Carenado pc12 manual

The Wasm stack machine is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to execute at native speed by taking advantage of common hardware capabilities available on a wide range of platforms.
WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand. The textual format will be used when viewing the source of Wasm modules on the web. WebAssembly is designed to maintain the versionless, feature-tested, and backwards-compatible nature of the web.
Open and debuggable WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand.

This is in large part due to the fact that the game has been made open-source, meaning that hobbyists and tinkerers are free to poke around game engine files and figure out how to get them running on otherwise unsupported platforms.
This is not a project that is directly associated with id or their owner ZeniMax, but it is entirely compliant with the open source license that the Doom 3 engine has been released under. I tested it on my Windows Laptop running Chrome, and I got solid performance out of it, it seems totally playable to me.
All I could do was stand still and look around. Perhaps if you pair a keyboard and mouse or gamepad it would work better. Performance is on the choppy side, and it took quite a while to download all the game files, but to even see this game that once required a bleeding-edge gaming PC running on a regular phone is quite impressive. Perhaps this could be the start of seeing Doom 3 make its way onto as many different platforms as the original Doom did.
This might be the last game from id to have its engine code released as open-source, since that initiative was mainly pushed by 3D graphics pioneer and open source advocate John Carmack, who is no longer with the company, so anyone hoping for Doom or other id titles to be released as open-source may be setting themselves up for disappointment.
Who knows though, and perhaps this web port could end up getting the official seal of approval from id, and become the basis for a fully supported and officially released web browser version of the classic shooter.

So, what is it? What use case is so compelling that causes such quick browser adoption? This post aims to explain the need for WebAssembly, a conceptual overview of the technical side, as well as a small hands-on example for context.
All this talk can evoke grumblings from those who argue that intensive applications are still best off running natively. But ultimately, no-one can deny the convenience that web applications provide end users — no installation means no disk space eaten, no local security worries, and no installation process. It also provides a large amount of appeal to developers, who only need to deal with one platform. Code only needs to be written once, and is far easier to support and maintain. WebAssembly was created with these high-level goals :.
You might be reading this and thinking that some parts sound familiar. It also suffered from the problem that it was never standardised, so performance improvements were inconsistent across different platforms. WebAssembly automatically supersedes asm. Figma moved their online editor from asm. For this simple example, all we need to do is include emscripten and let it know that we want to export the compute function.I am the guy who did this port.
Also, download code is dumb for now, it is downloading one big full. I know, it should be better to only preload necessary assets for sure! Smart streaming of game data is one necessary step for apps on the web.Nioh pc ds4 icons
Have you considered webtorrent or IPFS for distributing the file? Webtorrent in particular looks very easy to setup, and then the most your server would ever have to handle is the equivalent of a single downloader. I think it would be better to stream only needed data, using some lazy load mechanism. Still need to figure out what is the best approach. That's definitely the more permanent solution for games like this.
I was thinking more along the lines of quickly solving the immediate problem so you don't have to spend more money on a different server. I wouldn't be surprised if you could replace the download with a webtorrent in less than an hour of work and be done with it. Excellent job! I wanted to run the native copy for comparison, but it turns out you added support for the demo files yourself! What would you guess you could get the bundle size down to if you were to preload only the required assets?
I think a lot of us are curious as to how load-time performant webassembly games like this could eventually become. Swapping the pakfile for a WebTorrent or maybe a couple of them wouldn't be crazy, but I guess there would still be some trouble in keeping that from holding things up.
Once this stuff stabilizes a bit, games wrapped up as progressive web apps might become a thing. Could be an interesting way to get distribution outside of the app stores via regular search engines for a lot of indie developers using e. Also a nice way for mainstream game developers to show of demos without requiring cumbersome installations, lengthy detours via some app store, etc.Making a Commercial Steam Game in One Month
I hope you're right. We've had this capability for quite some time but for some reason it never takes off. Bastion released a version for Chrome's native client 7 years ago, the game ran amazingly well, but that version of the game doesn't seem to exist anymore.
NaCl was shut down in favor of webassembly so here's hoping. On the other hand i hope he's wrong because that means games can die at the whim of whoever hosts the servers they already have tons of issues with DRM and such. Personally i prefer to have control over when and where the games and other software i have are installed and i prefer to buy games from GOG and other DRM-free places that give me an offline installer i can place on my external hard drive whenever possible, but comparing the popularity between GOG and Steam with developers and publishers tells me that if the option for them to take even more control away from the consumers is there, the vast majority of them will go full on it.
This loss of control over the software i use is my main annoyance by far as a user when it comes to the trend of pushing everything as a web app. Oh, I completely agree with your sentiment but I don't think that means it has to be hosted remotely. No reason you shouldn't be able to download a packaged web binary to run locally. I wonder if webassembly supports that notion or not?
It does. It's just a spec for a bytecode, and it's designed with the intent of being run in the browser and natively.
