Through the Interface

Displaying streamlines in the Forge viewer

The integration of the MeshLine library into the Forge viewer – which we’re using for the display of skeleton data, as we saw last time – has opened the door to displaying all kinds of other cool stuff. Back in 2014 colleagues in Autodesk Research published a SimAUD paper entitled “Towards Visualization of Simulated Occupants and their Interactions with Buildings at Multiple Time Scales”. It explored the use of various visualization techniques to display how a building’s simulated occupants interact with it. One of these techniques was called Speedlines (we also use the term Streamline): The original visualizations were... Read more →

Displaying skeletons in the Forge viewer – Part 3

Right then… now it’s time for the really fun stuff. Looking back over this series of posts, we introduced it then looked at adding simple geometry to the Forge viewer, followed by animated skeletons and animated skeletons with fixed meshes attached. Today we’ll dig into making our animated skeletons properly visible. Having given up on using a SkinnedMesh, the remaining option was to tweak the underlying display of the SkeletonHelper object. This proved challenging for all sorts of reasons. Back in Chrome 55, it seems the ability to show lines with widths broke in three.js. This was fixed in... Read more →

Don’t miss these sessions at the Forge DevCon in Las Vegas

The Forge DevCon is a great place to dive deeply into what’s possible – and what will soon be possible – with the Forge platform. I’m involved in the organisation of the Las Vegas DevCon – being held on November 12-13, 2018 – in that I help lead one of the tracks. When the first DevCon took place, back in 2016, I was track-lead for the AR/VR track… these days I’m co-track-lead with my old friend Cyrille Fauvel for the Complementary Technologies track, which incorporates topics such as AR/VR, AI and robotics. All the really fun stuff, basically. ;-)... Read more →

Displaying skeletons in the Forge viewer – Part 2

We introduced the series, then looked at adding simple geometry to the Forge viewer, followed by animated skeletons. Now it’s time to look at approaches for making these skeletons more visible. As mentioned last time, today’s post is a bit of a “non-post”: it talks about adding a SkinnedMesh to be animated alongside an underlying skeleton, which we already know doesn’t currently work inside the Forge viewer. But it’s instructive to see the process in case either the situation changes or someone wants the code for a pure three.js application. Basically it’s possible to add a SkinnedMesh into a...

Displaying skeletons in the Forge viewer – Part 1

After introducing the series and seeing how we can add simple vertex and edge geometry to a scene, today we’re going to start digging into the guts of the problem of how to display skeletons in the Forge viewer. This proved to be a really interesting process: I ended up learning a lot about how the Forge viewer and the three.js library it uses both work. I don’t recall the full history of the Forge viewer’s use of three.js, but recent releases have all depended on r71. This can present challenges, largely because three.js is (at the time of...

Adding 3D geometry to a scene in the Forge viewer

In the last post I introduced the series where I’ll be talking about the journey I’ve been going through to add skeletion data inside Dasher 360 (which is, of course, based on the Forge viewer). The first step I took along this path was to find a way to add simple 3D geometry into an existing scene inside the viewer. This is something we do in a limited way inside Dasher – we use point clouds to represent the locations of sensors, for instance – but I wanted to work out the right approach for doing this for data...

Forge skeletons and disappearing signs

It’s been a strange few days. It’s the very last week anyone will be working from Autodesk’s Neuchatel office. This really hit home when the Autodesk name and logo were removed from the building, last Friday. Photo credit: Estelle Ormrod I salvaged an A (the were signs on the front and back of the building, so this wasn’t the only one) for my daughter’s bedroom. It’ll be some kind of reminder of the wonderful years we’ve all spent here. The staff departures have been staggered, over the last 6 months or so: there have been leaving aperos for people...

Registration is now open for Autodesk University, Forge DevCon and Connect & Construct 2018

Last Thursday registration opened for the latest edition of Autodesk University and its pre-conference events, Forge DevCon and Connect & Construct. I’ve just gone ahead and registered: I’ll arrive in Las Vegas on Saturday November 10th (to give myself a fighting chance of handling my jetlag before things kick off properly on Monday the 12th) and head home on the Thursday evening. My classes, this year, fall during the pre-conference and the first day of AU proper, which is nice, especially as it means you won’t need a full AU pass to attend (you can find pricing of Monday...

AEC Hackathon Berlin 2018

I’ve just arrived back from Berlin, which I was primarily visiting for this year’s German AEC Hackathon (last year’s was in Munich, which I attended briefly in the weeks leading up to our big trip). I was there with my family, and we had a great time visiting the city when I wasn’t needed at the Hackathon. Let’s start with a few tourist shots. On Thursday we visited a few places, such as the Holocaust Memorial… … and the Berlin Cathedral, which was beautiful inside but had stunning views across the city from its roof. We were staying with... Read more →

A visit to the MTC

On Sunday night I hopped back across to Birmingham airport in the UK in order to visit the Manufacturing Technology Centre (MTC) in Coventry on Monday. The weather has been gorgeous in the UK for the last month or more, so everything was a little parched. That, in combination with the fact England was still in the running for the World Cup, meant the country seemed imbued with optimism: seemingly welcome respite from the Brexit-related anguish the UK has been suffering since the EU referendum. After a nice dinner with old friends and a quick sleep at a hotel,... Read more →

Class recordings from AU London 2018 are now available online

The class recordings from this year’s Autodesk University held in London’s Tobacco Dock are now available for your viewing pleasure. Here’s the recording of the class I presented: If you’re interested in going a little deeper into the technical aspects of how we’ve used Autodesk’s Forge platform in Dasher 360, then I recommend watching this class from the Forge DevCon at AU 2017 in Las Vegas, where my colleague Simon Breslav presented similar material – but with greater depth – for an audience made up primarily of developers: We have a number of ongoing projects related to Dasher 360,...

Just a few weeks until the AEC Hackathon in Berlin

On July 20-22, 2018 I’ll be attending the AEC Hackathon in Berlin. Here’s some information about the event: The AEC (Architecture, Engineering and Construction) Hackathon is a weekend of geeking at its finest. It gives those designing, building and maintaining our built environment, the opportunity to engage, collaborate and interact on multiple aspects of the building industry. Not all built environment professionals have to code or have much background with tech. Just come with your knowledge, an open mind, collaborative spirit, and willingness to solve Mon-Fri problems leveraging various kinds of technology. We’ve shaped an exhilarating Program on Robotics,... Read more →

AU classes and Forge events

I’m on the train, heading to Geneva airport for my trip across to Barcelona for the latest Forge Accelerator. It seems there’s a good crowd in the room, already, so it should be a fun week. Yesterday I submitted two classes for Autodesk University 2018 in Las Vegas: I wonder what proportion of classes are submitted on the last day of the CFP period, and whether this number is stable, year after year. I usually try to submit my own classes earlier, but this year things have been a little hectic, for some reason. The first class I submitted... Read more →

Migrating Dasher 360 to use the Forge viewer v4.2 - Part 1

Over the last few days I’ve been battling with migrating Dasher 360 from using v3.2.1 of the Forge viewer to the latest & greatest at the time of writing, v4.2. Somewhere around the v4.0 release, quite a few changes were integrated into the viewer that relate to UI theming and docking panels. Some of these are really interesting: the UI feels a lot cleaner than it did with v3.x, for instance. To give a sense for how some of these changes might break an application, here’s what happened when I simply upgraded the viewer and stylesheet references in Dasher... Read more →

Checking out the world’s first 3D printed steel bridge at MX3D in Amsterdam

In a recent post I mentioned a trip to Amsterdam to visit with Van Wijnen and MX3D. The press embargo has now lifted on MX3D’s bridge – as you can see from a slew of recent articles – so I can now share a bit more information about that part of the visit. During that week I spent 2.5 days at MX3D, mostly to participate in discussions about how best to instrument the bridge with sensors. Autodesk started our collaboration with MX3D around the vision of using generative design for the creation of the bridge’s form… during the last... Read more →

Beyond BIM: adding campus or city views to Dasher 360

Those of you who have followed the progress on Dasher 360 will be aware that it currently works with a single building (or other) model. It’s always been our intention to go “Beyond BIM” (both in terms of addressing the needs of other industries but also scaling up to look at sites and cities) but over the last few weeks we’ve made a big push, making our first real forays into this new territory. Here’s a sneak peek at a campus view in Dasher 360 that integrates an additional Forge viewer control (this might also use a 3D mapping... Read more →

Blown away in Amsterdam

I was a little torn about my plans for this week: the Forge team is running a packed Accelerator in Munich, so it would have been great to have spent my week over there. As it happened I ended up coming to the Netherlands, instead, to meet with two incredibly innovative companies, Van Wijnen and MX3D. Despite missing the Accelerator the timing was actually pretty ideal: it proved possible to spend a day and a half with Van Wijnen at Autodesk’s office in Hoofddorp before coming into the city to join some of my Autodesk colleagues – Alex Tessier,...

A visit to Autodesk’s Advanced Manufacturing Facility in the UK

I didn’t think, on Monday, that I’d be visiting the UK this week. So it came as a surprise that on Tuesday I ended up buying a flight to head across to Birmingham on Wednesday, coming back Friday. You’re probably thinking, “ouch, that must have been expensive!” – which was exactly my expectation, looking into flights – but it turns out that at this time of year (probably due to the demand from skiers) EasyJet runs daily flights between Geneva and Birmingham. And – this week, at least – the flights were nearly empty: I managed to get a... Read more →

Hackrod is open to the crowd

I was really excited to hear, over the weekend, that our friends at Hackrod have launched a successful crowd-funding campaign and that there’s still time to participate. The campaign is being hosted on MicroVentures, which means investors should receive interest on their investment as well as equity in the project, assuming things work out. This admittedly seems a nicer model than getting a T-shirt or coffee mug saying you supported their Kickstarter. ;-) I haven’t yet decided whether I’m personally going to get in on the action (so to speak) but I thought I’d post about it in case...

Dasher 360 at the Advanced Manufacturing Facility

During a 3-day event, this week, Autodesk opened its Advanced Manufacturing Facility (AMF) in Birmingham, the UK’s second largest city. Here’s a video showing some information about this very cool facility. It’s one of 6 technology centres that Autodesk is running at various locations around the world. The others are Pier 9 in San Francisco, the Boston BUILD Space, Autodesk Toronto’s new MaRS office, the VR Center in Munich and the Materials Lab in Kilsyth, Australia. My team is proud to have been asked to provide technology to be showcased at the AMF: Dasher 360 is running there, providing... Read more →
