The NEST building’s HiLo roof

This week I was supposed to be back in Zurich for a couple of days, visiting the NEST building on Tuesday and the ETH campus on Wednesday. As it was, though, I managed to pick up Covid at last week’s TechX event in Atlanta, so I ended up staying at home feeling sorry for myself. I haven’t had particularly bad symptoms, thankfully: neither headaches nor fever, just mainly a heavy cough and a bit of brain fog, both of which are thankfully clearing up now. Given the value of last week’s event I’d certainly say that getting it relatively... Read more →

Working around the Chrome bug affecting the timeline

The amazing Mike Lee – who has been doing a great job of driving the timeline project for Dasher – has used his sleuthing skills to figure out a way around the bug affecting Intel-based Macs running Chrome v100 on Monterey. He was about to submit a bug when he discovered this ticket filed against Chromium, and a workaround buried within in. (Mike has since gone ahead and submitted his own report tracking this.) You need to go to chrome://flags and disable “Use passthrough command decoder”. After restarting Chrome and launching Dasher, you should now see the timeline is... Read more →

More on Tandem and Dasher

This week we’ve updated the Project Dasher site with a new build – the first update we’ve made in nearly a year. (I’ve talked about some of the rewrite work in a previous post, but it’s taken a while to get around to making it all available.) One of the major improvements has been with the timeline component. At some point in the future I’ll spend some time talking more about the timeline’s features – it’s available publicly via NPM and is integrated into the Forge viewer’s Data Visualization extension reference application – but for now I just wanted...

Harnessing the Tandem SDK inside Dasher

Back in September we started the work to integrate the (currently still internal) SDK for Autodesk Tandem into Project Dasher. This is what I’ve referred to, in the past, as “Tandem inside Dasher” (as opposed to “Dasher inside Tandem”). The work hasn’t been happening constantly: it’s been intermittent, as changes were needed to both Tandem and the core Forge viewer to support certain workflows. I’m happy to say that, as of this week, the integration is pretty close to having parity with the version based on the traditional Forge viewer, with a few gaps that should be filled in...

Three AU proposals to vote for and a deadline reminder

It’s the last few days to submit your class proposals for Autodesk University 2022 in New Orleans. The Call for Proposals closes on April 15th. I’ve now submitted three classes, myself, and would greatly appreciate you voting for the one(s) you would like to see part of the event. This is whether you intend on being there in-person in New Orleans or not: the vast majority of classes will either be livestreamed or recorded and made available on-demand for virtual attendees. Here they are. Voting is open until April 25th. Voxel-based Architectural Space Analysis inside Dynamo Building Digital Twins... Read more →

BIM World Paris 2022

On Monday I hopped onto the train to Geneva and from there onto the TGV to Paris Gare de Lyon. I was in Paris for BIM World, where we displayed the Dar 2m Smart Bridge. It was my first time seeing the bridge in person, which was a really exciting moment for me. After checking into a very nice little hotel in the 6th arrondissement I headed to the conference centre to help with the setup. The bridge was already unboxed and hooked up when I arrived. Pete Storey had some wires to connect to get it up and... Read more →

Detecting collisions in the Forge viewer

In a recent post we saw that switching to use THREE.BufferGeometry brought some unexpected benefits when it came to rendering robots inside Dasher. I wasn’t very happy about the fact that said robots were spinning destructively on the MX3D bridge, so I started looking into options for collision detection inside a Forge viewer application. From the start I should say that the approach that I ended up choosing is fairly rudimentary in nature: a much better solution would be to integrate a physics engine such as Ammo.js or perhaps even a voxelization engine such as VASA. But I figured... Read more →

Switching to use THREE.BufferGeometry in Forge viewer applications

I talked some time ago about some work that has been needed to be done in Project Dasher – and other Forge viewer clients – in anticipation of supporting viewers such as Tandem’s. In this case it was fairly specifically about the need to support loading of multiple models inside the viewer, rather than working on the assumption that there’s a single model available. For the last few days I’ve been looking at another area that by all accounts will be beneficial, whether driven by use of the Tandem viewer or the upcoming Forge viewer based on the latest...

Vote on my (and others') AU 2022 class proposals

I’ve gone ahead and submitted two class proposals for Autodesk University 2022. If you think they should be part of this year’s event, I’d certainly appreciate you voting for them: Voxel-based Architectural Space Analysis inside Dynamo Autodesk Research first created the Space Analysis toolkit - and its accompanying Dynamo package - to support 2D generative design workflows such as those used during Project Discover for the architectural layout of Autodesk's Toronto office. VASA - short for Voxel-based Architectural Space Analysis - takes these techniques to the next level, allowing the geometric exploration of architectural spaces in 3D for activities... Read more →

The recording of the March Tandem webinar

Last week’s webinar – where I was kindly invited by the Autodesk Tandem team to join them to talk about Autodesk Research’s explorations into the potential for Digital Twins in the AEC space, specifically through Project Dasher – has now been posted via the In Tandem website (under Resources). It’s also on YouTube, so you can watch it directly over there. One really interesting section was Tim Kelly’s demo (starting around the 26-minute mark) of work the Tandem team has been doing to integrate Dasher-like capabilities into the product. Really exciting stuff! Here’s a preview of that segment of... Read more →

Reminder: join the Autodesk Tandem webinar today to see the future of connected Digital Twins

The webinar is today (March 9th, 2022) at 4pm GMT | 5pm CET | 11am Eastern | 8am Pacific. If you’ve read this post in time, sign up here! Read more →

Walk across the Dar Smart Bridge at BIM World Paris for free!

This is all very exciting. I’ve booked my TGV ticket for Paris to attend a physical, in-person event: BIM World Paris is being held on April 5th & 6th, 2022, at Porte de Versailles. Autodesk is sponsoring the event, and the Autodesk Research team will be using the opportunity to show off the work that was done on the 2m Dar Smart Bridge, something I’ve covered recently in some depth. I’ll be attending along with my friends and colleagues Pete Storey and Fikret Kalay. In preparation for the event, I’ve been remoting into the PC running the bridge’s “operating... Read more →

Join the Tandem webinar in March to see the future of Dasher

The Autodesk Tandem team have kindly invited me to join their regular webinar – coming up on March 9th – to talk about the history of Project Dasher and to participate in a more future-centric discussion with Bob Bray and Tim Kelly. Here’s the description of the webinar. Even I want to attend, it sounds so interesting! ;-) From the lens of a software architect, learn why digital twin is key to the future of build What will it take to win the digital twin race? Get a front row seat and join our very own Kean Walmsley, software... Read more →

Placing sensors and evaluating their coverage using VASA

Last week I mentioned the release of VASA 0.2.0, which includes some new nodes and samples that raise some really interesting possibilities. I couldn’t help but come back to the “sensor coverage” sample (named 12-VASA-Sensor-Coverage.dyn), in particular, as I can see so many possibilities for its use. Here’s the description Rhys Goldstein included in the sample: A demonstration of how to combine sample point generation and proximity operations to select locations on walls and ceilings using the Voxel-based Architectural Space Analysis (VASA) package. In this example, the locations are used to place sensors and approximate their coverage. First, sample... Read more →

Building the 2m Dar Smart Bridge

Colleagues in Autodesk Research have been working with Dar Al-Handasah on a project to 3D print a series of footbridges with integrated sensors. It’s similar in some ways to MX3D’s Smart Bridge Amsterdam, but printing with plastic rather than steel. I’ve talked about the bridge at a couple of events, now, so I thought it was time to share some more information about this fascinating project. My role in the project is, once again, fairly minor: I’ve been helping with the visualization of sensor data from the bridge inside Dasher (more on that later on), but it’s been fun... Read more →

The NEST exhibit at the new Autodesk Gallery

Last week this announcement was made that included a video showing off the sparkling new Autodesk Gallery at our 1 Market Street office in San Francisco. There’s a lot of inspiring content in the new Gallery – for instance it showcases the results of Autodesk Research’s collaboration with NASA JPL, the generatively designed interplanetary lander, and the scanning robot from Forge partner Scaled Robotics – but I wanted to highlight a project that I’ve participated in quite a bit, over the years, and I’m super-happy to see has a place in the stunning new Gallery: there’s a scale model...

The recording of last week's BIM Fórum Brasil event

Our friends at BIM Fórum Brasil have now posted the recording of last week’s event on Digital Twins. (If the last link says "We Couldn't Find This Page", just click on the Brazilian flag in the page header.) A big chunk of the session is in Portuguese, but my piece was in English. If you only understand English, I suggest skipping forward to the 20-minute mark. If you’ve heard me talk about this topic before, you might still want to check out the section on the Dar Smart Bridge project at the 35-minute mark. (Be ready to crank up... Read more →

Speaking at tomorrow’s BIM Fórum Brasil about Digital Twins

I’ve been asked to talk about our work on Digital Twins (or Gêmeos Digitais) at the BIM Fórum Brasil event, on Wednesday of this week (January 26th, 2022). The event starts at 10am in Brasilia, which is 2pm in Central Europe, so the timing should work well for Asia, Europe and early birds on the east coast of North America, too. I’ll be sharing information on our older projects, as usual, but I’m also planning to showcase some of our more recent (previously unseen) projects. So there’s likely to be new information even for people who have seen me... Read more →

Draping temperature data from a thermal image across the Forge viewer scene - Part 2

In the last post we looked at how it’s possible to take temperature data from a thermal image and use the Data Visualization Extension to connect that information to locations in a 3D Forge viewer scene. In this post we look at how we can use the events from the same extension to display a simple tooltip showing the temperature when one of these locations is hovered over. Let’s start by looking at what we get from the thermal image. It’s pretty simple: we have colour. As we’re averaging a number of pixels it’s likely to be on a... Read more →

Draping temperature data from a thermal image across the Forge viewer scene - Part 1

I work in the Research Engineering team at Autodesk, a centralised pool of software engineering talent that contributes to research projects across our various industries. Organising this way allows us to explore commonalities (and efficiencies) that would otherwise be hard to achieve. Every year or two we have an internal “Innovation Days” event, which is essentially an internal team hackathon. (Lots of other teams at Autodesk do this, of course, we’re far from being unique in that regard.) Our latest Innovation Days took place on Thursday and Friday of last week, with the theme of sustainability. I met with... Read more →
