Through the Interface

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 →

A video on Generative Design for Architecture

The project I’m currently working on fits squarely under the umbrella of “Generative Design for Architecture”. We’re using Dynamo Studio to generate layouts of residential housing – including both individual homes and apartment buildings – with the results quantified in a number of metrics that will be easily explorable by the user of the system. It’s the approach The Living – the architectural studio in Autodesk Research doing pioneering work in the generative design space – has used for a number of projects, including Project Discover and the layout of the AU 2017 Exhibit Hall. I came across this... Read more →

Merging multiple graphs inside Dynamo Studio

I’m working alongside several Autodesk Research colleagues on a really large Dynamo graph. We’re mostly working in separate instances of the .DYN file – and focusing on different areas of it, as far as possible – and merging the changes together has been a task of which I’ve taken ownership. At the time of writing, Dynamo doesn’t have decent support for multi-user graph editing, nor is its data storage tuned for source control mechanisms such as Git. All of which makes identifying differences between graphs and merging updated areas to be quite challenging. One basic problem that we’ve had... Read more →

Controlling Philips Hue lights from Dynamo Studio

Now that we’ve seen a couple of posts showing how to query information about Hue lights via a Philips Hue bridge from Dynamo Studio, it’s time for the really fun stuff: controlling lights from Dynamo. To make this happen some changes were needed to the zero-touch node that talks to the Philips Hue API on behalf of Dynamo, mainly to allow the setting of a light’s properties. The Philips Hue API allows this to be done either via Hue, Saturation and Brightness or by the XY offset in the CIE colour space. I ended up exposing the ability to... Read more →

Accessing Philips Hue lights from Dynamo Studio – Part 2

In the last post we looked at some initial code to get basic information about the lights connected to a Philips Hue bridge. In this post we’re going to extend the code to expose more information but also to query the bridge repeatedly, allowing the graph to display the latest light colours as they change. Here’s a view of the updated graph. A few things have changed: firstly the Bridge object exposes some new information – in our case we can see the names of the lights, but we could also access the names and IDs of the various...

Accessing Philips Hue lights from Dynamo Studio – Part 1

I mentioned in a recent post that I was chewing on how design apps might connect with building automation systems to display data via lights. My first step along this path was to see how Dynamo Studio might connect into my home’s Philips Hue bridge and get information about the “smart” lights it contains. To do this I created a zero-touch node in C# that calls into the Philips Hue API exposed by my local bridge. (To make this piece work you need to follow the steps on this page that show how to create an authorised user ID... Read more →

Digging into Dynamo custom nodes

As mentioned in a recent post, I’m currently working on a project using Dynamo Studio. It’s fun getting back into Dynamo and DesignScript: I helped prototype the initial implementation of DesignScript inside AutoCAD about a decade ago, and I love seeing how the technology has evolved in the meantime. There are a few of us from Autodesk Research working on the project, which is also fun, but in a less literal way. Dynamo doesn’t work especially well with source control, as far as I can tell, so there’s a fair amount of manual merging of nodes into the master... Read more →

Isovist analysis in Dynamo Studio

It’s been an interesting first week in Autodesk Research. I’ve had the opportunity to jump into a few projects that are really interesting. One involves the use of generative design tools to perform a number of different analyses on design alternatives for an architectural project, assessing criteria such as maximum team co-location and improving the circulation of people through corridors. One the tools being used for the analysis is Dynamo: something I’ve been meaning to spend some time with for ages, but finally have good reason to. (Some of you may remember my involvement/interest in the DesignScript project… DesignScript... Read more →

A new version of DesignScript on Autodesk Labs

In case you missed it, last week Scott Sheppard announced the availability of a new version of DesignScript on Autodesk Labs. This release unveils DesignScript Studio which brings a visual programming environment to the DesignScript language. People who are familiar with Rhino Grasshopper or SoftImage’s ICE will be aware of the benefits of working with a graphical tool for mapping associations and flows of data. I personally prefer working directly in code, myself, but there are certainly times when this kind of tool can help unravel complexity. The other primary feature is a new lightweight OpenGL-based script execution tool... Read more →

In Singapore

I arrived yesterday morning in Singapore, coming in on a Singapore Airlines A380 from Zurich. It was a great flight, as far as long-hauls in economy go: comfortable seats with a great choice of films to watch (my favourite on this leg being “The Cloud Atlas”, an excellent adaptation of a brilliant novel lent to me by Jeremy Tammik a couple of years ago). I even managed to catch an hour or two of sleep, which is surprising for a daytime flight, even if it landed at 6am local time in Singapore. I rested for a few hours at... Read more →

Printing your own money with AutoCAD

Here’s a fun one to finish up the week. And no, it isn’t a belated April Fool’s gag. ;-) I should probably say right away that you won’t be printing money after reading this blog post, but you might know more about some of the security measures used by those who do. A couple of weeks ago, I received an email from Doug Bell at PaperMoneyWorld.net: I have tried your Spiro for AutoCAD and I enjoy it very much. I would like to challenge you to another function I would like to see that is related to the spirograph.... Read more →

Finding primes in AutoCAD using .NET

After introducing the work down by Carlos Paris on using AutoCAD to hunt prime numbers, we then looked at some DesignScript code that essentially recreates the core geometry Carlos used to visualize prime numbers. In this post, we’ll create some .NET code that iterates through the visualization, gathering primes and tagging them with rays to make them easily locatable. Now use AutoCAD as a graphical hash-table in this way is not the way you’re going to discover a billion-digit prime number, but the approach is interesting because it adds useful information to the primes visualization and also shows some...

Using DesignScript to visualize prime numbers in AutoCAD

In the last post we looked at some amazing visualizations of prime numbers created by Carlos Paris. I also mentioned I’d try my hand at replicating the basic visualization using DesignScript: it’s a good fit for solving this kind of problem (we want to create lots of repeated geometry based on the results of mathematical expressions). Incidentally, some readers of this blog have expressed an interest in learning more about DesignScript. I’ve roped in Robert Aish and Luke Church to share some of their insights into the design of – and uses for – the language, and so they’ll... Read more →

DesignScript now available for download from Autodesk Labs

I’m really excited about this. A new programming language and environment for AutoCAD is now available for download on Autodesk Labs (and here’s the announcement on Scott’s blog, in case, and you should also be aware of this login/download issue – something I just ran into myself). Way back when, I helped integrate the initial incarnation of DesignScript – although at the time we were using its working name, D# – inside AutoCAD. The father of the language, Robert Aish, was put in touch with me on October 17th 2008 and by the time I headed for Las Vegas... Read more →
