I was blown away by how accurate the | environment and maps were (at least in Chicago and Bloomington, | IL). By far the most realistic representation I've seen in a game | before. Even outside of the iconic buildings of downtown, a lot | of the smaller buildings in far out neighborhoods were more | realistic than I was expecting. | | I know the game has gotten a lot of praise on the graphics. I | guess they leaned heavily on bing maps to build out the game's | environment. Would be crazy to see what could be created with | something like google streetview data. | rpastuszak wrote: | Shame there's no free trial.

It's not something they facilitate and | definitely requires something of a hack, but it does work. | Then you can get the model into Blender, SketchUp, etc. and | start editing it to add or remove buildings and so on. | | Would be interested to know whether that's technically legal. | I mean, they put it out there on their website, right? | raylad wrote: | Only very vaguely related pet peeve: the term "Digital Twin" | implies that a simulation perfectly matches what is being | simulated. This is really almost never the case. | | Let's just call them what they are: simulations. | dharbin wrote: | Wouldn't it be a more compelling product if you sold the model, | not the model-making tool? If I was the city of Portland, I would | rather just buy the pre-made Portland model than have an intern | build it with CityEngine. | n8cpdx wrote: | CityEngine is a procedural generation tool, it isn't really | meant to compete with real world data providers. For something | like Google Earth but available as GIS data, you can use a | provider like NearMap. | | CityEngine is better for planning out and comparing future | scenarios, and other specific use cases. E.g. | https://m.youtube.com/watch?v=sOY3LY688QI | | Disclosure: I work at Esri but not in a sales role. I am also a | customer. | Nicholas_C wrote: | My SimCity nostalgia wishes someone would use this to make agent | based models of real cities with every citizen mapped out. | | Anything like that ever been done? | bragr wrote: | Have you played Cities: Skylines? There are definitely | limitations to its fidelity, but every person and car is | something you can click on and see their home, job, route. This | gives much more realistic traffic for one thing (though there | are mods that do an even better job). | | Ultimately though, I doubt that high fidelity simulations are | in the cards for consumer devices any time soon. Cities | Skylines already bogs down on large cities. | hutch120 wrote: | Stay away from ESRI (ess-ray) - I should get that printed on a | t-shirt. | | ESRI centralise power, lock you into their technology, and IMHO a | digital twin should be doing the opposite. Don't believe the | sales BS about ESRI having "free" software, read the fine print, | ArcGIS AINT FREE. | | IMHO a Digital Twin should be something for the people, by the | people! So please stop paying proprietary systems like ESRI and | incentivising them to stifle innovation and increases barriers to | entry. | | If you want to see local jobs, growth and innovation then invest | in OpenSource software like OSM (Open Street Map) and QGIS and | other Open GIS products. | mceoin wrote: | Your move, SF YIMBY. | prophesi wrote: | Does anyone know what the limitations are for the free trial? I'd | love to try this with where I live and experiment with it in | Unreal, and pay for a license if I do anything commercial with | it. | n8cpdx wrote: | Not sure about the trial. | | It's included with ArcGIS for personal use now, which is | $99/year and includes the rest of the ArcGIS system (except | enterprise server and the like). Obviously for personal use | only. | | We also released our maps SDK for unity and unreal: | https://developers.arcgis.com/unity/ | | Disclosure: I work at Esri but not in a sales role.
