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...

A visit to regenHU and farewell to Philippe

I had the pleasure of a visit from Peter Schlipf of the Forge Partner Development team, this week. Peter had come across for a number of reasons, but the first “task” was to catch up with Philippe Leefsma and wish him well for the next stage in his career. We met for an “apero” and then headed into Neuchatel for a lovely farewell dinner at the historic Cardinal brasserie. It was a lovely evening, but bittersweet: I’m very happy to see Philippe moving into an interesting role at an Autodesk customer, but sad that we won’t be working together... Read more →

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 →

Forge DevCon 2018 in Europe

The Forge DevCon is coming back to Europe, specifically to Darmstadt, Germany (on October 16) ahead of AU Germany (on October 17-18). While the content for AU Germany is presented in the local language, everything at the Forge DevCon will be in English. And it’s free to attend! Registration is now open for the event. There’s a great line-up of speakers delivering a packed agenda, so be sure to sign up soon. If you’re also interested in AU Germany, here’s a video showing a few highlights from last year’s event: I don’t yet know whether I’ll be attending, myself:... Read more →

Styling a logo and its associated text using HTML and CSS

While this is a relatively simple topic I thought it would still be valuable for someone out there who’s trying to do something similar for their web-site or -application. With v4.2 of the Forge viewer (and quite possibly before, but this was the first version in which I saw the change), the default highlighting of UI elements changed from a white glow to a colour-change to deep sky blue (#00bfff). I wanted to apply this same effect throughout the Dasher 360 UI, including the logo and text. In Dasher 360 the logo – a leaping deer – is separate... 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 →

Forge Accelerator in Barcelona

I’m back in Barcelona for this spring’s Forge Accelerator. It’s been an interesting week: I arrived on Tuesday morning – having missed the first day in an attempt to shave a little time off my June travel craziness – and arrived to find a number of attendees working on projects related to (and inspired by) the work we’ve done in Dasher 360. This is really encouraging… I’m thrilled to see others using Forge to tackle the kind of problems Dasher was always intended to help address. Onwards! The weather on Tuesday wasn’t great – a little windy and grey... 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 →

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 →

One man’s trash... Bjarne Stroustrup’s The C++ Programming Language

I came across this classic tome while wandering the halls of the Neuchatel office, this week. It’s one I remember reading when in my last year at University (in fact I’m almost certain I have a copy gathering dust in my basement). This particular volume once belonged to James Carrington (at least that’s my best guess from a Post-It on the inside that mentions his first name), who was an early member of the Developer Support team at the ESC (European Software Centre) in Neuchatel, way back when. This edition is from 1986, which I’m pretty sure makes it... Read more →

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

Last week I mentioned the effort to update Dasher 360 to use v4.2 of the Forge viewer (the most recent version, at the time of writing, and a fairly big jump from our previously-used version, v3.2.1). Here’s how Dasher 360 is now looking after these various changes: In this post I’m going to give more details of what specifically was involved in refreshing Dasher 360 to the latest Forge viewer, in the hope it’ll help people make decisions around their own use of the viewer and hopw/when they migrate their applications. Background As we’ve developed Dasher 360, we’ve done... Read more →

The Forge DevCon (and AU) 2018 call for proposals is now open!

This year will be the 3rd edition of the Forge DevCon. Once again it’s being held in Las Vegas on the Monday before Autodesk University 2018 starts, which for this year means November 12th, 2018. The “call for proposals” website is now live, and will remain open until June 11th. If you’re interested in submitting a class for this year’s DevCon then head on over: we’d love to hear from you! This year’s event will have the following tracks: Forge Platform and Roadmap Getting started with Forge and Forge APIs Community stories and case studies General web programming Complementary...

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 →
