Cambridge/Santa Monica, August 1 2019 – Arm and PlayCanvas are announcing the open sourcing of the renowned Seemore WebGL demo. First published in 2016, the graphical technical demo has been completely rebuilt from the ground up to deliver even more incredible performance and visuals. With it, developers are empowered to build their projects in the most optimised way, as well as using it to incorporate some of its performant features and components into their own projects.
“I’m so excited to be relaunching the Seemore demo. Open sourcing it in partnership with Arm will bring a host of benefits to the WebGL development community,” said Will Eastcott, CEO of PlayCanvas. “It’s an incredible learning resource that provides many clean, easy to follow examples of some very advanced graphical techniques. Sharing this project publicly is going to help move web graphics forwards for everybody.”
“PlayCanvas and Arm have always strived to push the boundaries of graphics and the original demo is a testament to that,” said Pablo Fraile, Director of Developer Ecosystems at Arm. “It’s encouraging to see how PlayCanvas have advanced mobile web rendering performance since the original demo. This re-release provides a unique resource into graphics for the mobile web that is both easy to follow and incorporate into your own projects.”
The Seemore demo was originally created as a graphical showcase for the mobile browser and takes full advantage of Arm Mali GPUs. It has been upgraded to utilize the full capabilities of WebGL 2, the latest iteration of the web graphics API. Some of the main features of the demo include:
Physical shading with image based lighting and box-projected cube maps.
Stunning refraction effects.
Interpolated pre-baked shadow maps as a fast substitute for real time shadow-mapping.
ETC2 texture compression to ensure that highly detailed textures occupy only a small amount of system memory.
Draw call batching.
Asynchronous streaming of assets to ensure the demo loads in mere seconds (approximately 5x faster than the original version).
Iterating on your PlayCanvas game just got a whole lot faster!
When you launch a scene from the PlayCanvas Editor, a set of assets has to be loaded. Non-script assets are loaded from the browser’s memory cache. However, script assets each generate a round trip request to the server. For projects with a lot of scripts, the load time can be long and your ability to iterate is going to suffer.
Today, we’re pleased to announce that we have deployed an update that introduces a lightning fast build step when you launch your scene that concatenates scripts into a single file. This means that only one HTTP request is made for scripts regardless of how many you have.
How To Enable The Concatenation Goodness
In the Launch button sub-menu, there is a new options called ‘Concatenate Scripts’. Check this to enable the feature:
What Difference Does it Make?
Your mileage will vary depending on how many scripts your project has and what your network conditions are. But if you have a lot of scripts, and you are subject to an internet connection with high latency (ping), then the speed up will be much more noticeable.
Here are the launch times for a scene referencing 125 scripts on low-latency WiFi (150Mbps down with 7ms ping):
Concatenate off: 24 seconds
Concatenate on: 2 seconds (!)
Wait! Won’t this Screw Up My Debugging?
In a word: nope! We use source maps to refer back to your individual scripts. So you can find your scripts in the Sources tab and set breakpoints as usual instead of having to navigate the super-long concatenated script file.
So we hope you like this latest improvement and that it makes your iteration time faster than ever. Enjoy!
PlayCanvas was born 7 years ago, way back on 9th May 2011. In the early days, we were essentially prototyping, seeing what this amazing new WebGL API could do. By October 2011, we set up a source code repository and committed our first engine prototype. Right at the beginning, we adopted semantic versioning for naming our releases. Our initial commit generated engine v0.10.0. From that point onwards, we adopted a rapid release cadence, often publishing more than one release a week. The months and years passed, our team grew and feature after feature was integrated into the codebase. But through all that time, we never incremented the major version number. Why? Well, there were several reasons:
Our rapid deployment meant we never delivered a monster release that seemed to warrant going to 1.0.0.
We always made a huge effort to maintain backwards compatiblity. Projects like the inane Doom3: Gangnam Style created in December 2011 still work fine today! So we never (intentionally) broke your projects.
We, uh, just never got around to it!
The semantic versioning site says:
How do I know when to release 1.0.0?
If your software is being used in production, it should probably already be 1.0.0. If you have a stable API on which users have come to depend, you should be 1.0.0. If you’re worrying a lot about backwards compatibility, you should probably already be 1.0.0.
The PlayCanvas API is now very stable, mature and battle-hardened. Backwards compatibility is something we take very seriously indeed. And today, PlayCanvas is used in production by thousands of developers.

And so, it gives me great pleasure to announce PlayCanvas Engine v1.0.0. I want to give my sincere thanks to all of the truly exceptional, hugely talented contributors who helped make this possible.
Today, Adobe announced that it is to kill Flash by 2020.
Back in early 2011, we foresaw this event and started work on PlayCanvas. We knew that Flash would still be around for some years, but we also knew that building any replacement for content creators would be a titanic task. Over six years later, PlayCanvas has established itself as the go-to toolset for building WebGL-content. The browser-based Editor application is lightweight yet exceptionally powerful. The apps produced are super-lightweight and perform great even on older mobile devices. And our ‘modern’ cloud-based approach enables developers to collaborate and iterate like never before.
Flash never did quite manage to establish Stage3D as a standard. WebGL, on the other hand, has cemented itself as the dominant force for web-based 3D, and has now reached version 2.0. In fact, PlayCanvas partnered with Mozilla back in January to launch the new standard. Flash has always been more popular for 2D based content and the remaining Flash developers must now find a path to migrate away. Spoiler alert: we’re working hard on improving our support for 2D. While it’s possible to make superb 2D content with PlayCanvas today (check out Master Archer, one of the top titles on Facebook Instant Games), we recognize there’s still more to be done in both the engine and the tools. We have some exciting announcements in the works regarding this so keep your eyes peeled.
Bottom line: Flash devs – we’ve got your back and we’ll be working hard to ensure you’ve got the tools and run-time you need.
Today is a huge milestone for real-time graphics on the web. Mozilla has launched Firefox 51, the first browser to bring WebGL 2 to the masses. WebGL has been around since 2011, the year when PlayCanvas was founded. 6 years on, the open standard for web graphics has taken a huge leap forwards, exposing far more GPU capabilities to developers, making for ever richer, more beautiful experiences.
To mark the launch of WebGL 2, Mozilla and PlayCanvas have teamed up to build ‘After the Flood’.
‘After the Flood’ illustrates many of the key, new aspects of WebGL 2.
Transform feedback: to animate leaf particles on the GPU.
3D Textures: used to create procedural clouds.
HDR rendering with MSAA: for correct blending of antialiased HDR surfaces.
Hardware PCF: for better shadow filtering at a lower cost.
Alpha to coverage: to render antialiased foliage.
…and much more.
So how was all of this done? As you know, PlayCanvas is an open source game engine. All of the work to integrate WebGL 2 into the engine can be found on Github.
Other key demo features are:
Compressed textures: DXT, PVR and ETC1 are used to reduce VRAM usage.
Asynchronous asset streaming: to get the demo loading faster.
Runtime lightmap baking: to generate realistic shadows that render fast.
Procedural water ripples
As you can see, PlayCanvas is all about squeezing the full potential from the browser. PlayCanvas apps, like ‘After the Flood’, look beautiful, load fast and perform great.
So what’s next? First, we will refactor and merge our WebGL 2 work into PlayCanvas’ mainline codebase. Then we will enable ‘After the Flood’ on mobile. And finally, we will make the demo project public so you can see exactly how we made it:
Universal launched the movie Ride Along 2 with a PlayCanvas-powered Truck Tour:
So what’s attracting incredible companies like these to PlayCanvas? It’s because they need WebGL tooling that works. Other game engines have let them down and PlayCanvas is delivering the technology they need.
2016 Tech Updates

Plenty of PlayCanvas games have been released during 2016 but we have to give special mention to Midgard’s BlastArena! It pays homage to the classic Bomberman with frenetic, insanely fun online play.
And we have to give special mention to our own online multiplayer game TANX! 2016 saw the game receive a massive upgrade, with stunning new visuals and level design.
PlayCanvas continues to race ahead as the leading platform for building lightweight, mobile-friendly WebGL content. We’ve got lots of surprises in store for 2017 and we can’t wait to share them with you. Happy New Year everyone!
We’re proud to announce that Disney has selected PlayCanvas to power their newly launched Hour of Code application. Entitled “Moana: Wayfinding with Code”, it’s a free online tutorial to teach kids the basics of computer science.
In the tutorial, kids are tasked with using code to navigate Moana and Maui, two of the main characters, through the ocean. When they’re attacked, the students have to use their coding skills to dodge the pirates.
PlayCanvas enabled Disney to bring the beautiful visuals of Moana to the browser via WebGL-based, realtime 3D graphics.
PlayCanvas’ web-first approach makes it incredibly easy to incorporate other web technologies such as Google’s Blockly and more besides. But it also gives great performance, particularly on mobile. And the tiny footprint of the 160KB engine makes for lightning fast download times and rock-solid stability all the way down to iPhone 4S.
Time for another dev update, WebGL lovers! We’ve deployed a ton of new features, optimizations and fixes. Here’s a run-down of what’s new.
A Camera Preview is now shown in the top left corner of Viewport when an entity with a camera component is selected.
Interactive Asset Previews
New Material, Model and Cubemap Previews are now available in the Inspector. They are interactive and clickable.
It is now possible to control antialiasing in Scene Settings.
When dragging a model to the Viewport from the Assets panel, if CRTL is held (CMD on Mac) it will put the model in front of the camera rather than at the origin.
Assets Panel Enhancements
Added toggle button to Assets panel to switch between small and large thumbnails.
Added Folder Up button to navigate to parent folder.
Hovering on asset in Assets panel will show a tooltip with the full asset name.
Asset Replace feature is available under the context menu of an asset. It activates the asset picker so the developer can choose another asset of the same type. It will replace references with new asset in Entities and Assets.
GIF files are no longer translated to PNG. They are now treated as another valid runtime format with parity to JPEG and PNG runtime texture formats.
Code Editor Enhancements
Highlight current line of cursor.
Made cursor more visible.
Fewer disconnection messages.
Huge speedups achieved for both loading and rendering of scenes!
New thumbnail rendering system reduces VRAM usage in the Editor by up to a factor of two. This makes the Editor more stable and faster to load, especially for larger scenes.
Major optimisations for loading and Editor rendering process so projects with thousands of entities and assets can load and render now up to 10 times faster in extreme cases.
Asset load operations are now batched rather than performed one by one.
All engine assets are loaded only when they are required (when they are enabled), leading to reduced traffic and loading times.
Optimisations in internal API of Editor and UI leading to reduced garbage collection (and therefore GC stalls) and speeds up UI templating for Hierarchy and Assets panels.
Enabled GZIP on WebSocket traffic, which reduces data transfers for initial loading.
Fixed up arrow while navigating in the Hierarchy tree.
Fixed sorting of folders in the Assets panel tree.
Fixed material overrides on the Model Component if the model asset wasn’t loaded.
Cubemap faces now update in the Inspector (in the Faces section) if a face texture file is changed.
Read-only users can now select text/number field values.
Double click or right mouse click on number fields now will select whole content of the field and not just part of number separated by a dot or minus sign.
Networking improvements have been made to reduce disconnects.
Phew! We hope you like these latest additions. Got any feedback? Comment on the forum! We’d love to hear what you think.
On Friday, 18th November, PlayCanvas HQ was visited by BBC News, the world’s largest broadcast news organisation. Our CEO Will was interviewed live on the 6 o’clock evening news which has viewing figures of around 1 million people.
It was a great opportunity to promote London as a great place for young tech companies to do business. Will describes the benefits for finding great talent, but London has so much more to offer. Outside of the US, London has the most active venture capital scene. Most international companies chose to locate an office in London. Transport links are superb. Government tax breaks are in place to assist tech startups, particularly in the gaming space. And on top of that, it’s an incredible place to live.
One of the most popular WebGL games today is TANX, our online tank battle game. WebGL brings developers amazing new possibilities: lightning fast load times, cross-platform play, easy sharing, incredible performance. It all adds up to instant, pure fun.
But as good as TANX is, we’ve been working hard on a major upgrade. And we’re happy to announce that it’s live today! So what’s new?
We’ve added a brand new level. We’ve moved away from the ‘TRON’ style graphics and adopted a more realistic style. Beautiful, I hope you’ll agree.
All power ups have been lovingly remodeled.
We’ve added a very sexy shield effect. See it crackle with energy as it kicks in. All done in a special custom GLSL shader.
To turn up the mayhem, we’ve added camera shake and punchy explosions, built with PlayCanvas’ particle system component.
Public Service Announcement: TANX is highly addictive. Please take occasional breaks!
Can you believe this game is playable after loading just 2.8MB of data? Massive fun delivered to your browser in seconds.
We hope you love this update. But what do we have planned for the future? Is there more to come? You’d better believe it! Our games team is now working full-time on TANX so expect continual updates over the coming months. Send us your feature requests and suggestions in the comments below!
