AU 2024 Days 0 and 1

On Sunday morning I headed across to Geneva Airport for my trip to Autodesk University 2024 in San Diego.The trip itself didn’t start very smoothly: I couldn't check in online - I suspect having two passports, only one of which has a valid US ESTA - meant that the airline flagged me for manual review. I really need to be more careful with my API (not the one I work with usually ;-) in future. Anyway, this check-in fail led to a cascade of irritations, from having to pay for a seat (to avoid being assigned a middle seat... Read more →

5 awesome VASA project ideas for the AU2024 Dynamo Hackathon

[My apologies for the click-baity title. I do actually have a list of 5 cool project ideas, if you scroll down the post. So it’s not completely dishonest, at least.] In the last post I mentioned a few classes you can sign up for (and that I’m directly or indirectly involved in) from the Tuesday to Thursday of the AU2024 week (October 15th-17th) in San Diego. I now have something to recommend for the Monday of that week, too! In the past we’ve often had pre-events at AU2024: I wasn’t sure whether there would be one this year or... Read more →

Using web workers to run intensive browser-side analyses in Autodesk Forma

The topic for this post relates to a project I’ve been working on for a few weeks, now. We’ve taken a complex set of spatial analyses - that use our favourite voxel-based architectural space analysis Dynamo package, VASA - and have translated them to work directly in the browser. (This translation process isn’t really the subject of this series, but it’s pretty interesting, nonetheless, and it’s mostly what I was working on during the recent trip to Munich for the DevCon. Most of the Dynamo code was fairly easy to translate, although things like the automatic lacing of nodes... Read more →

TechX 2024

In my last post I mentioned my trip to Las Vegas for this year's Autodesk-internal TechX event. This post summarizes the whole week, to give a taste for how these events go. Things started on Sunday evening at the Allē Lounge on 66 roof bar at Resorts World, where Autodesk's technical leadership community got together for a welcome reception. The view was spectacular! I have made a lot of friends at Autodesk, over the years, and TechX is my main chance to reconnect with many of them. I've known Alan Quinton since my days living in the Bay Area... Read more →

Back in Las Vegas for TechX 2024

It’s that time off year again: our internal Autodesk geekfest (called TechX) is being held this week in Las Vegas at the Resorts World Hotel. (It's held in a different city every year.) I’ve come across to attend a Technical Leadership Forum on Monday, and then present a TechX session on using WebAssembly to create a Forma extension (in this case using VASA) on Tuesday. I’ll also be participating in a number of other activities before heading home on Friday. As I wanted to be here in time for a reception on the Sunday night, I headed across on... Read more →

Using VASA with Forma via Dynamo

I’ve been talking quite a bit about our use of VASA inside Forma via our WebAssembly build of the toolkit (which is still not currently available publicly). I’ve done quite a lot of work to improve that particular prototype and I’m happy to say it’s shaping up nicely: the UX is much better than it was, for instance. I’ll be talking about our work on this at an upcoming Autodesk-internal tech conference, and as part of the preparation for this I’ve spent a few days building a pure Dynamo equivalent of the extension. VASA’s Dynamo package is available in... Read more →

Left to My Own Devices: I join the TRXL podcast for episode 152

Some weeks ago I joined Evan Troxel for a couple of hours to chat about my journey and some of the projects I’ve worked on. I’ve enjoyed the TRXL podcast for some time, so it was a real honour to be invited on. Our discussion has just been published as episode 152. If you prefer video, here’s the version from YouTube: Evan’s a great interviewer: I enjoyed the session a great deal and I hope you do, too. Listening back to it I realize there’s a lot more we could have talked about… hopefully Evan will invite me back... Read more →

Combining a translucent VASA visibility cone with intersecting Forma geometry

A very quick update on my holiday “fun”. After a bit of work I managed to combine two VASA voxel models - one for the visibility cone and one for its intersection with Forma’s site surroundings, something we saw last time - into a single Forma mesh. You can hopefully see that the performance is very decent, and the translucent, fog-like effect of the cone to be a reasonable visual complement to the intersection area. I ended up going through the extra effort to combine them both into a single mesh - putting the vertices together as well as... Read more →

Intersecting VASA's visibility cones with the surroundings inside Forma

This week I’m up in the mountains with my family. It’s my younger children’s winter half-term break, but as I do have a few meetings to attend during the week I decided to only take half days off: snowboarding in the morning and working in the afternoons. I found some time between meetings to work on the VASA inside Forma prototype. My goal for the week was to have the visibility cones displayed for our proposal building - something we saw in the last few posts - intersect with the surrounding geometry, whether other buildings or greenery of some...

More work on VASA inside Forma

This week I’ve been continuing some of the work I did during the recent Forma Hackathon in Oslo. Part of this was using the Forma Elements API to extract information about buildings included in the “proposal” being developed. For the Hackathon I’d hardcoded the size of the buildings - the number of floors and the heights of each floor - but the Forma team (thanks, Vilde!) has been helping me figure out how to get this information from Forma. In a nutshell, it’s possible to get the grossFloorAreaPolygons for the building of interest and then analyze the associated data:... Read more →

My VASA demo from this week's Forma Hackathon

I’m now back from Oslo, and decided to record the demo I delivered there at the end of the Forma Hackathon (or something approximating it, as I used twice as much time as we were each allocated on the day). Here’s a photo shared by the event organizers of me talking: Here’s the video I recorded this morning: As I mentioned at the end of the video, the capabilities I’ve demoed inside this Forma extension could also be implemented using Dynamo for Forma. That’s probably something I’ll blog more about, at some point, if there’s enough interest. Read more →

Forma Hackathon in Oslo

On Monday I headed to Zurich airport with our eldest son to hop across to Oslo. He’s between semesters at Uni - waiting for his exam results to trickle in - and it’s great we’re getting the chance to get a change of air for a few days. It’s rare that I sit in a window seat, so I was sure to capture the view as we left Zurich... … and arrived in snowy Oslo. The weather had impacted our trip very slightly - a 30-minute delay to our 2-hour flight - but we were still happy to touch... Read more →

AU 2023 class materials: Channeling Minecraft to Analyze Architectural Spaces with VASA and Dynamo

The recordings and other materials prepared for the two classes I helped present at AU 2023 are now available online. In today’s post I’ll point you to the first class, entitled "Channeling Minecraft to Analyze Architectural Spaces with VASA and Dynamo". This one was one of the first sessions of AU 2023, and had a very good crowd in attendance. Here are a few photos from the live session. Thanks again to Fernando Malard for snapping them. I already posted a quick summary of the content (without audio) - here that is again. Here is the material posted for... Read more →

Using VASA with Forma - Part 3

I was sure this series was finished - as indicated in the last post which talked about both VASA’s pathfinding and visibility from a point inside Forma, after having talked about a manual approach for connecting the two tools - but I did leave the door ajar to me finding something else to talk about on this topic. Sure enough, I got thinking about the missing “big ticket” item that VASA is able to implement with relatively low effort: visibility from a direction (as opposed to from a point) which can simulate things like shadows cast by direct sunlight....

Using VASA with Forma - Part 2

In the first post in this series we looked at an approach for exporting Forma geometry to an STL file that can be loaded into Dynamo and analysed using VASA, our Voxel-based Architectural Space Analysis toolkit. The overall goal is to be able to use VASA for urban-scale analysis of the site context. (Later on I hope we’ll also be able to work with more detailed architectural geometry as the level of detail in Forma evolves.) In that post I also alluded to something that’s coming soon which will streamline the above workflow: you’ll hear more about that at... Read more →

Using VASA with Forma - Part 1

While preparing for one of my upcoming AU classes, I decided to explore how someone could use VASA - our Voxel-based Architectural Space Analysis toolkit - with Forma. Right now Forma is largely focused on conceptual design - taking into account the surrounding urban context - so this thinking was largely focused on how VASA might be used at the urban scale. This is something we’ve looked at before in the context of FormIt and Dynamo. While a tighter integration is likely to be possible at some point - I’ll talk a little more about our work on a...

Preparation for AU 2023

It has been a really busy but important week for our team. We had a fantastic virtual offsite where we spent a significant amount of time using LEGO to conceptualise some of our planning for the coming year. A friend of mine was all set to become a LEGO practitioner - to assist with team-building events - before the plans were de-railed by the pandemic… independently my colleague Dagmara suggested we try “Serious Play” for this offsite and I said yes before she’d finished her sentence. We’ve made great strides for our upcoming exhibition in Toronto (formal announcement coming... Read more →

AU class registrations so far

As mentioned in the last post, it’s now possible for people to sign up for their AU classes. And it’s really worth taking the time to do so, as some classes are filling up quickly. Despite being held at a ridiculously early time on the first day of the conference, my first class is already 88% full, for instance (there are 141 registered and the capacity of the room it’s currently assigned to is 160). I see that 300+ people have this session in their list of favourites, so if you do want to attend then I recommend signing... Read more →

Voxelising point clouds in Dynamo with VASA

Last week we saw a Dynamo graph that imports a point cloud from an ASCII-based format to specify the initial locations for a fun flocking simulation. This week we’re going to look at a graph that uses a similar import technique but rather creates a voxel model based on the point cloud: The main difference from the previous import code is that rather than returning a list of Point objects, we’ve tweaked the code to return 9 doubles for each point that are taken as triangle definitions. The little secret is that the triangle’s vertices are coincident: we use... Read more →

Checking whether your class proposals have been accepted for Autodesk University 2023

Just a quick note to say that you can now log in to the Autodesk University website (this guidance has changed, please see below) from today – June 23rd – to see the status of your class proposals and learn whether or not they were accepted for AU 2023 in Las Vegas. I was very happy to learn that the two proposals I submitted this year were accepted: I’m sure there’ll be an email sent very shortly, but I just thought I’d share this in case anyone’s impatient to find out their situation relative to classes at this year’s...
