Sometimes in CityEngine it can be hard to figure out what’s going on. Whether that’s understanding scope (CityEnginers understand this can get complicated) or just simple metrics.
I’ll often use a combination of ‘print’ and ‘report’ to give me a better understanding of my code at any given point. What I also do is use bright colours (which have simple RGB/hex colour codes) to indicate whether a part of the code has been reached. once I’ve confirmed it works I continue the code.
Recently I’ve been working on some code where an understanding of the orientation of an model is important, not just as a world orientation but also relative to the initial shapes scope. As is the case with most of my work in CityEngine I start to wonder, how would I go about making something more visual for me? Thus I decided to spend some (okay probably too much!) time creating a procedural protractor. This allows you to switch between displaying an angle relative to the shapes scope, or the world.
I’ve used the Handle features in CityEngine to make interacting with the attributes associated with this rule simple. I’m starting to use ‘handles’ in CityEngine to expose attributes for users in a friendlier way.
To sum up for me I’ve found that programming language in Esri CityEngine called Computer Generated Architecture (CGA) is easier to pick up than traditionally programming languages because it is a visual one and by that I mean you create geometries.
I also get asked what PCs I run CityEngine myself, so here goes my list:
Asus Transformer Pro 3 (i5, 4GB RAM intel graphics card) – Works okay for small projects, I like using it for creating rule files ‘on the road’. If you want bigger city models don’t use this.
Razer Blade 15″ – (i7 8th Gen, 16GB RAM, 1060 GTX Nvidia) This is a fantastic games PC but also practically a desktop replacement, a new purchase for me but good for most things I would throw at my desktop.
Chillblast (i7, 32GB RAM,1070 GTX Nvidia) It’s the RAM that makes this great really and has the edge over my new laptop. Oh and I have 2 24inch screens attached.
For a client I’ve been working with CityEngine installed on Amazon Workspaces alongside ArcGIS Pro this seems to work pretty well so far but I haven’t push the limits (yet)!
ArcGIS Pro! If you working with Esri software anyway this is essential you can use it to publish easily your 2D and 3D layers. You can also use CityEngine to create Rule Paackages which can be used as advanced symbology in ArcGIS Pro. Users who only have ArcGIS Pro can use CityEngine rule packages which gives you more options to share your hard work.
ArcGIS Online for those looking to publish quickly an seamlessly to the web geospatial 3D data/models created in CityEngine you need to be using this. Obviously other platforms can be used, if you they can work with the CityEngine export formats.
I really recommend a 3DConnexion SpaceMouse (any of them) as well for navigating around all that 3D work. It’s not a replacement for your regular mouse but does compliment it greatly.
SketchUp is still a must have for all those fiddly details, CityEngine+SketchUp are perfect companions applications

CityEngine 2018.0 beta has been out for a while now and is pretty much over, I’ve been lucky enough to have been using it in anger for a bit too. Building on the CityEngine 2017.1 release there are some small improvements, new CGA code as well as a couple of new features, but essentially this feels like a minor release which is not a bad thing. Just because it’s minor doesn’t mean it doesn’t feel like progress , it will be well worth the update!
Firstly a confession, the title is a bit of a click-bait (hey if respectable news organisations can try it why can’t I?) I can’t show you a sneak peak this time or really talk about specifics, well because of um beta stuff and all that…. (last time I had a special agreement). What I can tell you is that if you want to participate in the future CityEngine betas you can sign-up here https://earlyadopter.esri.com . If you like CityEngine and are interested in where it’s going and of course helping out the team at Esri then I thoroughly recommend you sign up!
I can assure you that some bug fixes have happened and a couple of new features added which complement the analysis side of things.

This I guess poses a question for Esri, does it continue CityEngine long term with so many products that seem to tick the urban space box? As someone who has trained many clients in CityEngine and offers consultancy services over the last 5 years I certainly have an interest in its future! There are big questions of whether it will be just consumed by ArcGIS Pro or placed in some cloud container and interacted with via ArcGIS Online.
I think (and I have no insider knowledge here) the answer is all of these things will happen, but also that CityEngine will continue to be a standalone product for the foreseeable future. Esri is in the movie industry now and I don’t think it will want to leave that, but also CityEngine is a great design tool that fits Jack’s interest in urban and geodesign.
“is a simple-to-use 3D city editing and visualization tool” – “Build Flexible Scenarios Faster” – “Create Realistic Context”
The real worry for me is what form will CityEngine evolve into. The marketing literature still talks of easy operation and high quality realistic outputs. Sorry but it’s not easy to learn or use (from a typical planners perspective) and the high quality outputs don’t come instantly (unless you like Redlands building typologies!).
CityEngine’s great power is it’s flexibility of format support and usage. But it has fundamental technical issues/challenges with terrain and roads that need addressing. Esri also needs to decide whether this is a tool for the drag and drop users among us, or some highly technical development environment for urban planning.
One glimmer of light and a direction of travel is the ESRI.lib folder, promisingly for new users it shows a path of drag and drop produce something now. Unfortunately this seems to have gone a little stale, anyone who does CGA coding in CityEngine knows organising and keeping up to date rule files is difficult especially if projects vary like ours do. The ESRI.lib has some great rules I use over and over again, roads and trees, in fact the more generic the better! Give me more of those tree assets! These smaller rules enable a greater freedom and I can write rules that work with these easily because I know they are installed with every CityEngine workspace.
In conclusion, and I’m not good at concluding thoughts so forgive me, CityEngine is here to stay but has some challenges to overcome. Like all software it has to evolve as it’s users ask more of it. Currently I worry that CityEngine as a tool is too technical for widespread adoption this means that businesses will be reluctant to invest in it if only a hand full of users (CityEngine professionals) are out there. On the plus side CityEngine professionals like myself will probably have some consultancy work coming our way!
Update and response from Esri Zurich’s R&D Director
So I posted the link to this blog on LinkedIn and amazingly Pascal Muller (read a post I did called Life Changer to understand why I am honoured to get this) very kindly responded. I have got his permission to post those comments here, these have been copied directly and no editing has been done although I have tried to keep the paragraph breaks. What I now need to do is a follow up post to contemplating this response!
Thanks Elliot, really great read!
I could answer some of the raised questions : ) hmm, maybe we should do an ‘ask me anything session’ here…
(1) You are correct, not a ton of new features in this release. Reason is that we changed our release cycle this year and are releasing now 3 months earlier. As a result the time between CE 2017.1 and CE 2018.0 was much shorter. CE 2018.0 comes out next week and you can expect CE 2018.1 in September instead of November.
(2) Yes, CE is here to stay. There are no plans to discontinue it. In contrary: maybe you have heard about our new product initiative ArcGIS Urban which is basically a streamlined urban planning platform (on top of AGO) for the planning departments of cities. It will feature cool web apps/interfaces and it will also work great with CE. It’s all developed under the same roof here (also includes the 3D JS API 4.x team btw). In the ArcGIS Urban context, CE will (still) be required for the more advanced workflows such as for example Devin’s site plans, Bruno’s Masterplanner, or the various greenfield mega city projects of the HOKs and F+Ps.
ohh, and of course Blade Runner 3 will need these off-world cities Batty was talking about : )
Besides all this, CE continues to be one of Esri’s development platforms where bleeding edge technology gets applied before it goes mainstream, see for example the push on game engines (more about that later…).
Pretty exciting stuff and I am extremely happy that all the pieces fall into place finally, but we know that we have to keep working hard and improve things. Huge thanks for your continuous support and wise long-term thinking.
Well it had to happen eventually, we’ve got our first British Cartographic Society 3D Special Interest Group (or 3DGBCS) meetup coming at the end of March, hosted at the Ordnance Survey offices. Nicholas Duggan has been leading this and will have finalised the details shortly, be sure to keep an eye out for it on social media as well as here.
Now on to more news: we’ve had tremendous support in setting up the 3D Group and we want too extend this. As such we have setup an award specifically for 3D cartography of any sort from any industry or profession. This bit is important really as the term 3D can be all encompassing and we didn’t want to limit who entered, you don’t even need to be a member of the BCS. In our work we’ve seen representations of the world in 3D from many industries just look at the entertainment industry for a wide range of 3D technologies and let’s be honest mapping/cartographic techniques. In urban planning and architecture 3D representations of the world around us provide important context for proposals. With smart cities a 3D basemap is considered integral to the bringing all this city data together.
3D Cartography Award 2018
The first annual 3D Cartography Award Sponsored by GD3D® the 3D geospatial brand from Garsdale Design, is a new exciting award open to everyone in any industry creating interesting, informative, exciting 3D cartography (real or imagined) using any technique and/or medium!
Currently we find 3D representations all around us, whether it is a web map, a survey plan, a planning visualisation, or even a computer game. This can come in many forms from a simple isometric drawing through to full haptic virtual reality.
We don’t care what industry you are in or what software you use, whether you are a surveyor, cartographer, GIS user, artist, engineer, data scientist, or other, we just want to see your amazing 3D representations and hope the entries will challenge everyone’s perception of what 3D cartography is!
There are many interpretations of what 3D cartography is, so we don’t want to limit entries. We propose an award for an overall winner based on communication of the intended message, legibility, simplicity, visual impact, and composition. There will also be commended awards for those we see as having merit in particular areas, science, statistics, visualisation, urban, natural environment, fictional, and other.
Entries will be considered by a panel of judges, appointed by the GD3D® team at Garsdale Design and the BCS Awards Committee. The panel will include a range of people from different areas of expertise in the 3D data industry. The panel will judge the quality and design of the map in relation to the purpose for which the map was produced.
The winning entry will be announced at the BCS-SoC Conference in September 2018. The award comprises a crystal trophy to be retained by the winner and a certificate. The winning entry will be put forward for the BCS Award. Those commended will receive a certificate.
All entries will be exhibited at the BCS-SoC Conference and the winners will be published in The Cartographic Journal and on the BCS website following the Awards Ceremony.
We don’t want to limit the entries but as guidance below is an example list of entry types. This list is not exhaustive, and the judging panel will consider other formats as appropriate:
VR formats compatible with HoloLens, HTC Vive, Apple & Android
Some of our latest CityEngine work is looking at the high street and in particular here at home the UK high street. Commercial buildings in a typical UK town are a mixed bag of traditional older buildings with some often badly maintained concrete buildings and the odd brick built modern monster designed and built in the 1980s. More recent buildings like glass a lot … We’ve been creating rules to describe building frontages, not all are pretty but that’s kind of the point!
Further to my CityEngine Quick Render post I thought I’d put through some of our GD3D buildings (sourced from CyberCity3D and processed for use on the ArcGIS platform sold via ArcGIS Marketplace) through the same process. I think they look quite nice! My next task will be to start showing more than pretty renders of buildings, I hope to add some metrics in and the do more nice imagery.
All this rendering of 3D models whilst not new to me is something I do very rarely, other people can do better but as with everything it is nice having some skills ‘in-house’!
I’ve been playing with my new ‘Craftsman’ style CityEngine rules in other workflows and pipelines. The one I’m working through at the moment is some experimental renders, I know there are a lot of issues here but I’m not yet interested in spending hours working and tweaking my rendering program to get ‘just’ the right level of detail and dirt (there are better professionals than I for that). It’s still amazing to me that these are proper GIS based models (they mostly designed to work with GIS data in ArcGISPro) with real dymanic metrics being now used to produce something that looks quite good (well I think it does).
I like how these renders make my craftsman style models look like something you may print out via a 3D printer. Okay it I know it looks toy-like, and is somewhat dated in terms of visual renders etc.. (I’m not a entertainment industry/graphic artist professional) but I still like it. Also apologies for over use of Depth of Field effect….
