Introducing VASA, a tool for Voxel-based Architectural Space Analysis

I’ve been hinting about this for a few weeks now, but today is (very excitingly) the day for the big unveiling. My colleague Rhys Goldstein has been working his magic, once again, taking the algorithms he developed for the 2D Space Analysis package and applying them to 3-space. If you were impressed by Space Analysis, what we’re showing now may just knock your socks off. The new package is called VASA, which stands for Voxel-based Architectural Space Analysis. It’s available today for download from the Dynamo Package Manager. It’s worth unpacking a couple of terms, here: voxel-based means VASA... Read more →

A minor update to Space Analysis (2D), and getting ready for 3D!

This week I’ve been getting my Revit installation working again – it had been a while since I’d used it, and it was overdue an upgrade from 2021 to 2022 – mainly because I have to publish a couple of new packages (or package versions) to the Dynamo Package Manager. The first is a minor update to the Space Analysis package, taking it from version 0.3.3 to version 0.4.0. There is a breaking change, however, in that people using the Visibility nodes from Python may have to modify their code to use the correct (newly added) namespace. We only... Read more →

Bundle optimization in Project Dasher

I mentioned recently that I’ve been working on updating Project Dasher’s use of 3rd party components, and that I had some learnings to share. We started the Forge-based version of Dasher in 2016, and (much to my shame) some of the components had stayed at more-or-less the version available at that time, largely due to the migration effort needed to deal with breaking changes. Biting the bullet to upgrade them was painful but necessary, and right now I (and Dasher) feel nicely refreshed. Last time I mentioned there were two big outstanding dependencies that still required attention: Bootstrap and... Read more →

Build your first Digital Twin at the upcoming Forge Hackathon

Other that my regular foolings-around with ancient tech, I feel like I’ve been neglecting this blog in recent weeks. That’s all about to change, though, as we enter the busy period leading up to Autodesk University 2021. For one I have some interesting learnings I thought I’d share from some of the foundational work I’ve been doing on Dasher’s codebase, but there are also some interesting updates for people performing analyses of 2D (and 3D!) spaces. Fun stuff! First though, it’s worth reminding people of the Forge Hackathon that’s around the corner. It starts in just a couple of... Read more →

A minor makeover – and a lot of core work – for Dasher

Over the last week I’ve been heads-down on core Dasher work, but with very little visible result. Here’s why. Early last week I received an email telling me that it was time to dig into Dasher’s use of 3rd party components and make sure there weren’t any security issues. (This isn’t something unusual – all our products go through this, and many of our research projects, too.) As anyone working on web development projects will know, it’s important to go through from time to time to reduce the technical debt that accumulates due to the use of old libraries... Read more →

A new face in the Autodesk Tandem team

My friend and colleague Hali Larsen has joined the Autodesk Tandem team as a Product Manager focused on connected workflows and sustainability. This is huge news, for lots of reasons: for several years Hali played an absolutely instrumental role in Project Dasher – in many ways she was our de facto PM, but also worked through many gnarly issues related to bespoke configuration for various Dasher pilot projects. Hali has a wealth of experience working with customers in this space, and also knows where most of Dasher’s skeletons are buried, so she is the right person to take on... Read more →

Previewing and viewing PDFs inside Dasher

A couple of days ago we were looking for the datasheets for the various sensors installed in the MX3D bridge: as you’ve probably already read, there are nearly a hundred sensors in and on the bridge, although of only about eight different model types. My colleague Josh Cameron said, in passing, “it would be really handy to have these datasheets integrated into Dasher!”. As usual, this sent me down a rather fun rabbit-hole for a day or so, to see how we might reasonably integrate these PDFs into Dasher. Firstly it’s worth pointing out that these days the Forge...

Dynamo 2.12, MaRS v3 and the future of Space Analysis

The latest update to Dynamo Core (which for now you can use via Dynamo Sandbox) has some really interesting enhancements, both in terms of usability and performance. Check out Sol Amour’s two blog posts that introduce Dynamo Core 2.12. As it had been a while since I’d tried the MaRS graph in a new drop of Dynamo, I went ahead and loaded it. I immediately noticed a couple of things: it was referencing an old, now-deprecated version of the Solar Analysis package, so I updated to the latest & greatest version on my system and then reloaded the graph...

Using the Forge viewer? It’s time to switch to SVF2!

The big news on the Forge side of things over the last few weeks is probably the official release of SVF2. This is a more efficient streaming format the Forge viewer (from v7.25 onwards) can consume. We’ve been using SVF2 (which was previously known as OTG) for the last couple of years inside Project Dasher, and it’s been brilliant. If you’re interested in the technical details on SVF2, be sure to check the blog post that announced the SVF2 Beta from late last year. Just for instance, we’ve seen significant performance improvements from using SVF2 for our public demo... Read more →

Come and work for Autodesk Research in Pier 9!

San Francisco’s Pier 9 has got to one of the coolest Autodesk office locations to work from. You have access to all kind of cool technology, and it’s also full of pretty cool people, too. As a reminder, here’s an old post that shows the office, and here’s another that introduces the work we did there to prototype technology for the MX3D bridge. If this is the kind of work environment that gets you excited, then you may be even more excited to hear that our team is hiring for Senior Web Developer (someone with full stack development skills)....

Data from the MX3D smart bridge

The MX3D team first showed the smart bridge to the public back in October 2018 at Dutch Design Week in Eindhoven. I was there with the team to finish and test features such as realtime display of skeletons detected using computer vision. Here’s a reminder of how that went: An interesting aspect of the public’s response to the bridge at DDW2018 was that it had broad appeal to people but that people appreciated different aspects of the project: The majority view: “wow, what a cool-looking bridge!” Those who dug a little deeper: “it was 3D-printed by robots? Interesting –... Read more →

The MX3D bridge opens to the public

On Wednesday afternoon I headed back across to Zurich airport for my second trip to Amsterdam in as many weeks. This time I was flying with Swiss rather than KLM, and ended up checking in and boarding through an area of the airport I didn’t recognise at all. Whether this was because it had been so long since I’d been there or due to some deep refurbishment being completed during the pandemic remains to be seen. By the time I arrived in Amsterdam, things had progressed significantly with the MX3D bridge. Here’s a fun staged photo by Thijs Wolzak... Read more →

Autodesk Tandem is now officially available

These are busy times in the world of digital twins at Autodesk! I'm thrilled to see the news that Autodesk Tandem has now officially launched. Head on over to the new landing page, intandem.autodesk.com, to find out more, or check out Bob Bray’s recent article. A few people have either been congratulating me or asking how this relates to Project Dasher, so I think it's worth clarifying the situation. Tandem is not Dasher, although I'd love to think that the Dasher story at least in some way influenced or inspired Tandem's trajectory. Tandem solves a fundamental industry problem that...

Lowering the MX3D bridge

Now that the weekend has passed and the football is over for another year or so (for me, anyway, as I only pay attention to major tournaments), I thought I’d share some of the work that was done last week on the MX3D bridge, and what’s planned for this coming week. The major work done on Friday was to raise the bridge (allowing access to the current foundations) and to start the job of lowering it. Sometimes you have to go up to go down. I was impressed by the fact the bridge could be raised – one end... Read more →

An update from Amsterdam

It’s now Thursday night, and tomorrow morning we’ll be heading home from Amsterdam. As with any project, some things haven’t gone quite as smoothly as they might, but more on that in a bit. My son and I proudly donned our MX3D T-shirts for this morning’s pic: Here’s another shot from the bridge itself, looking down the canal. Now for some information about the main issue currently impacting the project. Here’s a video I took while on the bridge, that shows a quick walkover and the canal views. As you can see, there’s an issue with the clearance between... Read more →

First glimpse of the MX3D bridge installed

This morning I headed with our eldest son (he’ll be 17 in just over a week – how did that happen?) to Zurich airport to catch our first flight in what seems like forever to travel to Amsterdam to see the MX3D bridge being installed. Even catching the train was surreal: I’ve certainly done so, during the pandemic, but only for personal trips. My usual habit of grabbing breakfast in the dining car didn’t go so smoothly when I realised I could no longer remember the PIN for my corporate card. Luckily I could go contactless – SBB breakfasts... Read more →

The light at the end of the… smart bridge

This weekend I had a very strange task to perform: I had to book travel for work. Remembering how our corporate travel system worked was just one hurdle to cross – beyond that I had to deal with getting the appropriate management and travel department approvals, along with the fact I’ve booked a separate ticket for my 16-year old son to come along, and wanted to be 100% sure that we’re on the same flight. Was life really this complicated pre-pandemic? I’m sure I’ll get used to it all again, before long. The reason I’m travelling is pretty exciting,... Read more →

Applying heatmap power to single-sensor volumes

I’ve been heads-down on a side project to integrate a C++ library into Forge using Web Assembly (hopefully I’ll share more on this sometime soon). Thankfully while I’ve been busy on that, the Hyperion team has been beavering away on some changes to their core shader. Last week I realised – now that we have controls to adjust the confidence and power settings in the shader – that rooms with just one sensor have a uniform shading style. This was a deliberate choice we made, back when we initially implemented the shader, as we felt it would help highlight... Read more →

Integrating Hyperion’s object shading into Dasher – Part 2

In the first post in this series we looked at how a heatmap can be used to shade an object using the Forge viewer’s Data Visualization Extension – or Project Hyperion. In our case we shaded the surface of the MX3D bridge. In this post we look at a slightly different use-case for this mechanism, where we want to shade a piece of geometry inside the model based on the value of a particular sensor. To be clear: this is about shading the entire object a uniform colour that varies based on the value of the sensor that’s providing... Read more →

Setting the vertical position of planar heatmaps

In a recent post we talked about the integration of Hyperion’s planar heatmap capability into Dasher. Towards the end of that post, I mentioned that the Hyperion team was looking into exposing some way to place planar heatmaps not only at the minimum and maximum vertical locations in the bounding box, but at levels in-between. The team has delivered this more quickly than I expected, and you’ll be able to try it for yourselves in v7.45 of the Forge viewer. While I was adding the sliders needed for the capabilities shown in the last post, I went ahead and... Read more →
