Automating operations inside Dasher

In the last post I neglected to remind people of Kiosk Mode, a great way to see some of Dasher’s features. Simply click on the filmstrip button at the bottom of Dasher’s vertical toolbar and move the cursor off to the side (this just stops the button from staying highlighted when the cursor gets hidden). Then just sit back and see how Dasher works. Here are some posts talking about how this works. Kiosk Mode knows about various Dasher extensions and can automate their usage. There’s a fair amount of complexity in the mechanism, but it works well enough.... Read more →

Come and try the latest Dasher – now with a new timeline!

After many months of effort, we now have an updated version of Project Dasher available on dasher360.com. (The project is still very much active research, so for now you’re able to try it out with the model of the NEST building, accessible via the Demo button on the main page.) The major feature of this update is the new timeline, which was designed by Autodesk Research and developed by our partner CCTech. This component has been under development for over a year, so it’s really exciting to finally get it into people’s hands. Beyond that, you should really give... Read more →

A significant update to Dasher is on the way

For the last week or so I’ve been busy making sure Dasher works well with multiple themes. You can see the progress across these posts. I’m not quite ready for a full unveiling, but it should go live at some point in the next week, give or take. In the meantime, here are some screenshots of the main page (you’ll be able to select the theme either as you enter Dasher via the front page or from within the application’s settings UI, which is integrated into the Forge viewer’s). One of the big-ticket items in this coming release will... Read more →

Changing HIG themes at runtime in a Forge application

Despite the unfolding horror of the situation with Covid-19 – and stuff is really starting to hit the fan, here in Switzerland, with schools and non-essential commerces being closed and rumours of an enforced sequestration being considered – I’m at least getting some quality time to work on Dasher. Last week we saw how it was possible to support both dark and light themes from the Autodesk HIG in a Forge viewer application. I mentioned both times my desire to allow Dasher’s theme to be selected by the user at runtime. After searching fruitlessly on the internet for some... Read more →

Using the HIG to implement a light mode in a Forge application

Last time we saw how it’s possible to use Autodesk’s HIG to add different visual themes to a Forge viewer application. When I first started down this path, I thought I’d probably just stop at implementing another dark theme inside Dasher: I suspected it would be a lot of work to implement a light theme. It turns out I was wrong: towards the end of last year I’d spent a few days rationalising our use of styles inside Dasher, by eradicating every use of “hardcoded” colours inside CSS styles and have them stored in SCSS variables. It felt like... Read more →

Supporting multiple visual themes in a Forge application using the Autodesk Human Interface Guidelines

I mentioned in the last post that I’ve been working on integrating a new timeline component into Dasher. By default the component supports a different visual theme than the one we’ve been using in Dasher: in order to make the look & feel consistent, I had to include Autodesk’s HIG toolkit in the Dasher project. HIG stands for Human Interface Guidelines, and it’s Autodesk’s effort to increase visual consistency across our products (especially those that are web-based). And the best thing is, it’s open source and available for anyone to integrate in their projects via npm or yarn. And... Read more →

Knowing when operations are complete in the Forge viewer

We have a feature in Dasher called “kiosk mode”. It basically takes control of the browser to run a sequence of operations that show people how Dasher works. I published a series of posts a couple of years ago that explain a bit about how we implemented it. One of the issues in kiosk mode is knowing when Forge viewer operations – such as view transitions or state restorations – are complete. Until recently the code just checked the viewer’s progressbar property, to see whether its value was close to 100 or not. This wasn’t ever a very good... Read more →

Persisting identifiers for objects in the Forge viewer

In Dasher we have some interesting functionality to isolate parts of the building by level. This is increasingly something you can do via “out of the box” Forge viewer functionality, but we’ve found a couple of reasons to go beyond that basic capability: Not all elements or objects are assigned to the correct level. Some elements – such as those belonging to the building facade or perhaps internal pipes – transcend levels, and so don’t behave well. It’s of course possible to split elements/objects that belong to the second category, but we tend to take the approach of allowing... Read more →

More data from the NEST building now available in Project Dasher

I’ve been heads-down this week on a couple of tasks related to Dasher: the first relates to working on the integration of a new timeline control. I’m hoping this will be ready for people to try in the coming weeks, but we’re not quite there yet. The second relates to bringing more data into our time-series back-end from the NEST building: I noticed last week that we were missing data from October of last year onwards. It turns out we had a credentials problem – we have a “conduit” that regularly federates the NEST data into our back-end, but... Read more →

Migrating custom Forge viewer shaders to WebGL 2 – Part 2

A few posts ago I mentioned some work was needed to migrate our Dasher 360 shaders to the latest version of the Forge viewer (or the one after it). This work is now complete, so I can share a few thoughts and comments on what was needed to make this happen. Before doing that, though, I need to thank Elias Cohenca for his invaluable help during this process: I can honestly say that without his help the migration would either not have happened or would remain a work in progress. Thanks, Elias! Firstly, it’s important to note that even... Read more →

Visiting NEST with Kingspan

On Wednesday I was back at the NEST building on Empa’s Dübendorf campus. I’ve posted about NEST lots of times over the last few years, but these are the main two tours in case you want to track its evolution. I was there to meet Brian Glancy – visiting from Kingspan in Ireland – and Reto Largo from NEST. NEST and Kingspan are two of the main ongoing pilots of Dasher, so it was great to get everyone in the same place to discuss possibilities. Reto started the tour in the media room in NEST, with it’s 16-screen media... Read more →

Migrating custom Forge viewer shaders to WebGL 2 – Part 1

An interesting thing happened when I tried Dasher 360 with the latest production version of the Forge viewer: no sensor dots appeared. As Dasher without sensors is a glorified 3D viewer, this was a bit of a problem. Digging into things a little, I worked out that our custom WebGL shader wasn’t working properly in this latest version. At this point I reached out to my friend Elias Cohenca in Tel Aviv for a quick sanity check: he confirmed that this latest version of the Forge viewer is now defaulting to WebGL 2.0. This was confirmed in the Forge... Read more →

Swissbau 2020

Bright and early, yesterday morning, I hopped on a train (well, a couple of trains) to get across to Basel for this year’s Swissbau, the bienniel construction-related trade show held in Switzerland, and apparently one of the largest in Europe. I’d never been before, but thanks to social media I’d compiled a list of people to see there, and had even coordinated to meet up with my friend and fellow blogger, Jeremy Tammik. There was quite a bit going on at Swissbau, even outside the exhibition hall. At one point I saw some people performing while suspended from a... Read more →

Visually clustering the contents of models in the Forge viewer

Some of you may already have seen Augusto’s tweet showing the “Visual Clusters" Forge viewer extension that has been developed by the BIM 360 Design team. It really is super-cool: the extension takes the content of the model loaded in the Forge viewer and clusters it spatially based on the value of the various items’ category property. The extension was first published in v7.6 of the Forge viewer, so it’s been around a little while. If you don’t have a Forge viewer application to test it out with, fear not! Petr Broz has added the capability to load extensions... Read more →

Additively Manufacturing Music using the Printesizer

I mentioned in the last post that I had a fun topic to share to help get the new decade started. Well, here it is! I’ve been collaborating with Elias Cohenca from our Tel Aviv office on and off over the last few years: Elias managed to port the THREE.MeshLine JavaScript library to work with THREE.js r71, making it compatible with the current releases of the Forge viewer. We’ve made heavy use of this library in Dasher 360 to represent skeletons and streamlines, for instance. I’ve also been mentoring Elias, something I mentioned in this post from the middle...

My AU 2019 classes

The Autodesk University elves have been working day and night over the last few weeks to prepare 674 AU class recordings for posting to web. Some of my classes were livestreamed, this year, so I have already posted recordings for these. This post is just me gathering the various recordings together in a single post. Before that, though, I did promise a festive photo for each of the coming posts. Here’s one I took this morning, when we woke to find that St Nicholas had passed by the house. The feast of St Nicholas – which is celebrated throughout... Read more →

Reliving AU in Amsterdam

As the festive season is upon us, I’ve decided to start each post with a seasonal photo. Here’s me with a reindeer/dog (reindog?) in the lobby of the hotel we stayed at in Hoofddorp. As mentioned in the last post, Sander Lijbers made the most of my vague suggestion to meet with a customer or two during my visit to the Netherlands by inviting many of the accounts he manages to a one-day event in our Amsterdam office. Everyone accepted – with some even flying in from the UK – so we had a really good, engaged group! Sander... Read more →

Digitalisation workshop at TU Delft

After not being good for very much last week – while recovering from AU in Las Vegas – I headed back across to the Netherlands on Monday afternoon. In Geneva airport there was a large stuffed reindeer just sitting there. A huge thanks to Ben Rand for pointing out the obvious: that Rudolph is probably a big fan of Project Dasher! :-) I took the train from Schipol down to Delft, which was feeling very festive. I love Dutch train stations and the connectivity between multi- and two-wheeled transport. I had a very nice room in a hotel close... Read more →

Wrapping up Autodesk University 2019

Wednesday and Thursday were my busy days at this year’s Autodesk University in Las Vegas. After a breakfast meeting with a colleague from Toronto, I had my first class of AU2019 to deliver. It was a live-streamed class that was focused on advanced visualization (primarily of IoT data) using the Forge viewer. Somewhat unfortunately the class was scheduled at the same time as the AEC mainstage (more on this later), but that basically just meant that the room wasn’t completely full and that most of the attendees were Forge-focused. As it was live-streamed the class recording is already available:... Read more →

An updated model of the NEST building, now live on Dasher 360

A few days ago our friends at BIM Facility AG sent through a new version of the Revit model for the iconic NEST building. This version is much more complete: it has the award-winning Urban Mining and Recycling Unit modelled, as well as having a significant amount of additional detail (furniture, etc.) elsewhere in the building. The DFAB House has also received a makeover, getting more realistic materials, plus the ability to see into its ground floor and robotically-printed supporting wall. Considering all the hard work the BIM Facility team has put into making this version so much better,... Read more →
