Animating robots in the Forge viewer

The inspiration for this post has come from a variety of sources. (Feel free to skip this preamble where I talk about the history of the project: as much as anything it’s so I remember myself how things happened when I come back to this post at some point in the future. ;-) My colleague, Simon Breslav, worked on an initial implementation in Dasher 360 that animated robots – and even mapped stress information to their surfaces – for a demo shown at AU 2017, back when I was travelling around the world with my family. One of the... Read more →

When in Rome

It’s been a great few days in Rome, at the Forge team’s first ever Roman accelerator. Things kicked off on Monday morning, as we occupied the conference room at Rimond’s office in Rome’s Trastevere district. As is usual at these events, there are a number of companies doing really interesting things: several of them have specifically mentioned Dasher 360 as their inspiration for visualizing additional (even IoT) data in the Forge viewer. Very cool. Yesterday I joined Peter Schlipf to visit Roma Tre University, where we spent some time with Stefano Converso from the Architectural Design department, as well... Read more →

Counting down to Forge DevCon Europe

We’re just a few weeks away from the 2nd European edition of the Forge DevCon. It’s being held in Darmstadt on October 16th, the day before this year’s AU Germany. This is a free, English-language* event where you can learn all about the capabilities that are currently (and will soon be) available through the Forge platform. (* I’ve seen a number of emails asking whether the event will be in German or English, presumably due to its proximity with a German-language event. I can confirm that the entire program will be in English.) Here are some “reasons to attend”,... Read more →

Rob|Arch 2018

I spent the latter half of last week at ETH Zurich, attending a conference entitled “Robotic Fabrication in Architecture, Art and Design 2018”, or Rob|Arch 2018 for short. This is the biennial conference where luminaries in the AEC industry get together and plot how robots will replace millions of construction jobs over the years to come. Not really, of course: the big thrust of this conference is to work out how robotic fabrication technology might (or must) be applied to meet the housing needs of a planet whose population is expected to increase by nearly 30% over the coming...

The Autodesk Reality Solutions SDK and importing custom point clouds into AutoCAD

This isn’t exactly new news, but it was to me. Today I found out we’ve made a very useful component, the Autodesk Reality Solutions SDK, available to the public. This is a C++ library that allows you to read and write Autodesk’s RCP and RCS formats, as well as to create custom plugins for new point cloud definition formats. ADN members can log in today and download the SDK and accompanying samples. Non-members can send an email and get access to it that way. There’s a particular reason I find this to be important news: it will enable developers... Read more →

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...
