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….
So it looks like CityEngine 2017.1 is soon to be released (it gets released for Partners a little earlier!) and wow have the team in Zurich and Redlands been hard at work! Of course there are two headline features
The amazing viewshed/view corridor analysis you can do against your models here (oh and the can be controlled by python too!). Unfortunately for now it looks like you can’t export the analysis, but it is a great tool for understanding building heights and volumes within CityEngine itself. I did a small sneak post a couple of weeks back which is here.
High-end architectural visualisations with Unreal Engine, basically we have a new exporter function for Unreal Engine based on the Datasmith SDK. This seems to replace the FBX workflow and allows a more efficient way of getting your cities into Unreal. It looks like its capable of tens of millions of polygons!
It looks like the Esri team are making good on their promise of making CityEngine into a true geodesign tool of great value to Urban Planners. There are a lot of enhancements and bug fixes
Among the new CGA functions I think the interesting on of mention is the new annotation attribute @Enum and a change in how @Range works we can also restrict the values (so you can’t as a user override these values in the inspector!). This allows for a more defined set of inputs and makes the inspector much easier to read and interact with. @Angle, @Distance and @Percent do what they say and I think go some way in making people who author rule files (like myself) make easier to use tools!
One improvement I’ve noticed is that that the Scene Layer Package export function has been improved to make it what Esri call ‘Smart Mapping-ready’ basically it means attribute information is written to the scene layer package which makes it nice and easy to change colour by values in the online scene viewer.
A big thank you to the Esri engineer who fixed the bug in the FGDB export that meant previously imported feature classes retained memory of their old names when exporting!
Finally a reminder this release CEJ files (CityEngine Scenes) are not backward compatible with 2017.0! Take my advice, use a new workspace directory per CityEngine release and copy old project to the new workspace so you don’t run the risk of damaging your work!!
Some of you may have noticed a post I shared on LinkedIn by a gentleman called Ryan Johnston from the Transport Systems Catapult (based in Milton Keynes) coming to our office here in Cumbria last Friday.
Getting the train this morning to Cumbria for some collaborative work with Elliot Hartley#Garsdaledesign . Looking at how City Engine can help create fast environments for testing and stimulation.
Ryan was here to gain insight into how we here at Garsdale Design build virtual 3D environments from GIS data. We use the Esri platform to do this and one of the key tools Ryan was here to get an understanding of was CityEngine and ArcGISPro. As you all should know by now is that at Garsdale Design is well known for our CityEngine and 3D GIS expertise!
This is part of the Peterborough way finding research project for the partially sighted. Helping to understand how spatially correct 3d urban models and VR technology; can help the partially sighted to navigate from the train station to the RNIB Peterborough head office.
Ryan’s visit was in relation to a way-finding project for the partially sighted in Peterborough, home to the head office of the Royal National Institute for the Blind (RNIB). Here the TSC has brought together a range of industry professionals (such as Garsdale Design and MK Surveys) to create a virtual environment to test various sensors, beacons and navigation methods around Peterborough town centre and the offices of the RNIB. As this project progresses more information will be posted on the Transport Systems Catapult website.
Ryan was here the whole day (interrupted only by a nice lunch at the Three Hares Cafe), and we discussed various project workflows, for example making all that nice Ordnance Survey MasterMap data 3D, as well as managing terrain data. We looked at game engine workflows and the exciting possibilities of Unity as well as the new datasmith tool for Unreal. Of course once we have a dynamic and flexible (i.e. easy to modify) 3D model we also need to look at analytical tools to help in the process of assessing various ‘way marking’ technologies. Whilst the discussion was focused on the Peterborough project we’re happy to report that many of the issues we were addressing also would come in use for future projects too.
At the end of the day Ryan and I were able to make a quick mock-up of part of Peterborough to identify where CityEngine tools may help create this virtual environment. We also looked at the 2017.1 beta version with viewsheds which could be useful in this particular project.
We had a great day and it was fantastic to work with Ryan, I’m pretty sure we could have kept going for a lot longer, but sadly a work day must come to an end sometime!
I’ve recently shared some fun imagery from a CityEngine rule I created for a project I’m working on via social media channels. They’re obviously North American ‘Craftsman’ style homes. I thought a quick blog post with imagery here would nice to share with you. The Screenshots are deliberately low-res sorry!
You may have seen that I was out in the United Arab Emirates a couple of weeks back. I was there for two reasons, one to conduct a CityEngine training session for a number of GISTEC clients (we do this training here in the UK either with EsriUK or at our offices in Sedbergh as well as worldwide). As always training often turns to bespoke advice and discussions around workflows and use cases.
Basically, most things that a client asks for with 3D GIS can be done, you just to have a clear idea of what you want (oh and a budget!), technology (hardware and software) has progressed so much recently that most clients are now spoilt for choice.
Want a smart city? Well you may need a 3D basemap. Do you have any sensor data? If so what’s the quality? The answer invariably to all these questions and more is “it depends”. That’s why on the 20th of September I went to help present at our friends and partners GISTEC 3D GIS workshop/seminar event in the Roda Al Bustan in Dubai.
As a new format for GISTEC we were all excited and apprehensive to see how invited guests and clients would respond. We shouldn’t have been nervous as the response was overwhelmingly positive. The sessions allowed people to find out what was possible with particular aspects of the Esri platform and where they could join up some of those dots. My discussion table didn’t just talking about CityEngine. We talked about data acquisition (from UAVs for example, in fact I used demo data from the UAV table), about smart cities and story maps. The day was designed to find out more about everyone’s workflows and problems as well as informing and discussing potential solutions.
The format was informal and less about a sales pitch and more about discussion (no one likes presentations which basically say ‘buy me’). We had divided the session up into tables and each table had a theme to talk about (mine was Geodesign and Urban Planning of course!). The table’s moderators also used flipcharts and post-it notes to engage with the attendees and come up with problems and solutions around each table’s theme. This meant that at the end of the day each table had gained insight into some of the issues surrounding 3D GIS (in for example designing cities) but also discussed potential solutions and workflows (as well as software) to help. These flipcharts and notes would then be shared with the attendees as well (not just the table group but everyone).
Each table’s theme discussion was led by an expert in their field and as you can see we had some amazing people:
Smart Cities and IoT Solutions – Smart City and IoT
Andrew Rippon – NXN
Getting 3D-GIS Data from 3D-CAD – BIM to GIS
Nandakumar Menon – GISTEC
Data Capturing and 3D Data Preparation from Drone – Working with Drones Giuseppe Catania – b-link
Texturing Your Landscape and Building VR Solution – VR Solutions
Dileep Verma – Cirqus
Building Different 3D Applications – Working with Story Maps
The largest group of attendees had come to hear about smart cities and the ‘Internet of Things’ from Andrew Rippon of NXN (formerly Nexgen group) from what I heard (and saw a little of) this was a well received talk and discussion on some issues and challenges as well as the amazing solutions NXN are implementing for smart city projects.
The day ended with a quick panel summary of each tables discussions and a question and answer session. Questions about workflows and interest in what was possible seemed to be the main concerns. All in all I really enjoyed the day with GISTEC and the attendees I think I may have learnt more off of them then they did of me!
Well I’ve been a bit busy as of late working on some exciting 3D projects and attending some really interesting conferences! One day I’ll get around to writing about them. 🙂 There is so much going on in the 3D GIS space that it can feel a bit too much. Fortunately that’s where our expertise lies, making sense of it all and helping clients.
I’ve made some time though to talk a little bit about the new CityEngine 2017.1 Beta that I’ve just installed. But before I continue this is a sneak peek at a beta release some or all features I talk about maybe removed at the last minute, don’t plan your future projects based on this blog. What I would say is yet again, if you are thinking of working in 3D and the Esri platform, CityEngine is worth a look, especially for planners.
The team in Zurich seem to be hell bent on adding new features quickly now especially for the Urban Planners among us! I wanted to show you a very cool new feature/toolset called viewsheds. This gives you live (see animated GIFS below) views of viewshed domes or corridors in the CityEngine viewport, giving you an indication of what you would see from particular vantage points. You can change the colour for each area too (colour visible by all, colour visible by one, colour not visible by any) and place multiple viewsheds.
There are some usual bug fixes and a few new rule functions I can see coming up (I may write about these later), and there is a facility to import and synchronise feature layers hosted in ArcGIS Online! This brings some potentially exciting opportunities and workflows but as a new feature I think as usual this should be used with caution, but the direction of travel here is interesting.
While you’re here it would be good to know what you think of CityEngine and/or it’s direction into Geodesign and planning. Add a comment to continue/start the discussion (all comments reviewed/moderated).
I’ve not done this before but I think this is an interesting PhD topic for someone and of course there is a 3D city angle!
University College London and the Ordnance Survey are currently inviting applications for a 3-year PhD studentship in “Creating Dynamic3D City Models for Smarter Cities” which will examine the creation of multiple 3D models from a single data source (through generalisation/abstraction). The PhD will be supervised by Dr Claire Ellul (UCL) and by Jeremy Morley (Ordnance Survey). The closing date is the 28th July.
