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 →

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...

BrickBot – an Autodesk Research project exploring the future of manufacturing

Last month Fast Company published an article about an interesting project Autodesk Research has been working on for a number of years: internally the project was known as LEGOBot, but now that it’s being talked about publicly it has understandably been renamed to BrickBot. BrickBot is a really cool project that’s built on two core ideas: robots are stupid and engineering is expensive. Robots need a lot of help to be told what to do, but telling them what to do is neither straightforward (today) nor flexible: you need to code for specific conditions, and if those conditions change...

Introducing Warnamo, a Dynamo package for managing warnings and errors

One of the highlights of last weekend’s AEC Hackathon in Berlin was getting to meet Michael and Keith from the Dynamo team. They’d delivered a pre-event workshop on the Friday and stayed on to tutor the many Dynamo-centric teams participating in the weekend’s Hackathon. On afternoon on Saturday Keith and Michael presented an additional session that briefly mentioned Refinery (the optimization engine for Dynamo that’s currently in Beta) but focused mainly on the API infrastructure that enabled its integration into Dynamo: the View Extension API. It was really helpful for me to see how it’s possible to extend Dynamo... Read more →

My AU 2018 classes… all about Generative Design for AEC

I’ve seen a few of these postings via LinkedIn, and thought it was time to post something of my own. As mentioned previously, I submitted three class proposals for this year’s Autodesk University in Las Vegas. Two out of three have been accepted: the ones focused on Generative Design for AEC. I’m really excited about the first one, in particular, and it seems like it may also be featured in one of the pre-conference events (more on this once things get confirmed). I think it’ll be really cool to look at the project we’ve been working on with Van... 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 →

Voting for Autodesk University class proposals

The call for proposals for Autodesk University 2018 has ended and people have the opportunity for vote for their favourite classes. Head on over to this page and start voting for the classes you’d like to see at AU 2018. From my side, I’ve submitted three different class proposals for AU 2018. I don’t expect (or want!) them all to make the cut, but I’d be happy to receive your votes for the ones that interest you most. My favourite proposal is actually a class that would have 3 speakers, two from Autodesk and one from Van Wijnen. The... 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 →

SimAUD 2018

On Monday afternoon I flew back across to the Netherlands, this time from Bern airport. My main purpose for this trip was to attend the Symposium on Simulation for Architecture and Urban Design, or SimAUD, in Delft. I’ve been staying at an Airbnb a little way out of the centre of town, the advantage being I’m just across from a really pretty park. Delft is a university town and is a bit like a smaller, easier version of Amsterdam. There are canals everywhere… … and almost everyone seems to travel around by bike: I rented a bike from a...

NEST in Zürich

Yesterday I headed across to Zürich for a number of different meetings. One that I wanted to talk about on this blog is my visit to Empa, the Swiss Federal Laboratories for Materials Science and Technology, and – in particular – their NEST building. NEST is a testbed and showcase for emerging techniques in the construction and operation of buildings. They have a heavy focus on modularization, pre-fabrication and robotics. I’d been invited to visit by Reto Largo, Director of NEST, along with Philipp Mueller from Autodesk’s Education team. Reto wanted to hear about Dasher 360, while I wanted... 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 →

Bringing geometry from Dynamo into Revit

It’s been a quiet week on the blogging front, mainly because of the May 1st holiday on Tuesday, but also because I’ve been heads-down on projects I can’t really talk much about. One thing that does seem worth sharing is an approach we’ve been using to take geometry from Dynamo into Revit. The project itself relates to the use of Generative Design for urban planning. I can’t yet talk about the generative aspect – which is extremely cool – but once the design is basically finalised there’s a need to bring the geometry into Revit. The ideal scenario would...

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 →

Simulate and control industrial robots with a new open source plugin for Autodesk Maya

Colleagues in Autodesk’s Office of the CTO (OCTO) – who work in the robotics lab on Pier 9 – have just released the code for a new tool called Mimic. Mimic is an open source plugin – with the Python code posted on GitHub – that allows you to simulate and control the use of a number of industrial robots (including various robots from ABB and KUKA). Here’s a screenshot: I’m really happy to see OCTO releasing open source projects in this way. If you’re interested in contributing to the project, be sure to check out the developer notes....

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,...
