00:01Flying and driving around 3D virtual cities can not only be fun, like we did earlier…
00:05…but also incredibly valuable when it's applied to understanding and designing our world.
00:10However, the challenges have been in creating the 3D data. It takes time to build 3D simulations.
00:17We're going to show you some new approaches and techniques to address these challenges…
00:21…and create a whole new environment for 3D geodesign and simulation.
00:26Please welcome our 3D product manager, Gert van Maren.
00:34Thanks, John. With the 10 release, ArcGIS became a complete system for 3D GIS.
00:40And the response has been very positive. The number-one comment we got from you as users, though, was…
00:47…We would love to go 3D, but we only have 2D data. How can we create great 3D data?
00:54Well, let me show you how. As Jack mentioned earlier, we've acquired Procedural, maker of CityEngine…
01:01…and this offer allows you to take your GIS data, apply Procedural rules, and generate high-quality 3D content.
01:10Here we have CityEngine with building footprints coming from ArcGIS and attributes such as building height.
01:20Now I can select all my building footprints and apply a rule to generate 3D buildings.
01:27Now a rule is basically a script file that tells the software how to generate 3D content based on your GIS data.
01:35Now in this case, it's just a simple extrusion, and we're applying generic random textures.
01:41If, however, you have more information available in your GIS about your buildings, such as number of floors…
01:49…floor height, or roof type, the system can take that information and improve the quality of the 3D models.
02:00Now you can edit your data by either editing attributes in ArcGIS or changing the rules in CityEngine.
02:09So here, for example, I can change the roof type, and I can also generate a higher level of detail for this specific building if needed.
02:22And if you already have existing 3D models for your buildings, you can easily integrate these as well into the city scene.
02:39I can also drag in street centerlines and apply a street rule to generate 3D streets.
02:48And in this case, I'm using the width attribute in the GIS data to derive the width of the 3D streets.
02:56You can really model your city the way you want it based on your GIS data.
03:02But not only can we create 3D content, with this software, we can design in 3D as well.
03:10Let's have a look here at this empty area in the middle of my city.
03:14I have parcel data with attributes such as maximum building height, setbacks, and offsets…
03:20…and I can apply a residential urban planning rule to generate 3D massing models that reflect the planning regulations.
03:30And I can then further fine-tune my design by changing the rules.
03:36So for example, I can change the distance to the parcel boundary, I can enable my setbacks…
03:44…and I can change the setback distance. And you saw that the model was updated instantly.
03:52So one great feature of CityEngine is that it supports so-called styles.
03:59And styles are sets of predefined rule parameters that make it very easy to change between different design proposals…
04:07…or to improve the quality of your design.
04:14So in this case, you see that we improved the façade quality of these 3D massing models.
04:21Now finally, to finish off my design, I need to add a street.
04:28So I can very simply draw a street, and you will notice that the rule is automatically applied.
04:39And then I need to change the width of my street to make it fit in between the buildings…
04:44…and then I want to make it actually not a street but a footpath, so I apply a footpath rule.
04:52Now you'll notice that I drew my footpath straight across this main street, so what I now very simply and easily can do…
05:00…I can drag it up, and you'll notice that CityEngine automatically creates a bridge in this location.
05:15Now once you're finished modeling your city, you can bring it back into ArcGIS for further analyses…
05:21…or export it out to high-end simulation engines.
05:25And over the coming months, we will further integrate the capabilities of CityEngine into the ArcGIS platform.
05:31And this will enable anybody that needs high-quality 3D content, such as urban planners, facility managers…
05:38…architects, users in the defense and simulation industry, to easily create and design in 3D.
05:47This truly is amazing technology created by a great team in Switzerland. It is exciting.
