3d networks in CityEngine

CrispinCooper — Thu, 12 Dec 2013 15:33:44 GMT

Is it possible to import a 3d network to cityengine - i.e. one with z-data or elevations, that will be rendered as bridges or tunnels as appropriate?

Also if a network extends inside a building (e.g. pedestrian walkways) is there an easy way to display this?

Hi,

even though that CityEngine does not have a proper solution for converting 'networks' ( attributed 3d lines ) into nice geometry ( though that's planned ), many of these things can be done in CityEngine.

I assume you want to visualize such data in 3d ?

That's the plan, yes. Two problems really - (1) to visualise 3d networks; (2) to visualise 3d networks when they extend inside buildings/the ground.

I'd like to visualise a 3d network in a city. Would it be possible to

1. create generative city model from building plots + building height data in cityengine
2. export that model into arcscene
3. visualise my 3d network in arcscene?

I know arcscene can handle 3d networks, and view lines inside other objects (by making those objects transparent) so if the export process is possible that would seem to be the answer.

Hi Crispin.

Then I'd recommend to create the buildings based on CGA code directly within ArcScene ( 10.2 ) with the new GP Tool for this. CityEngine 2013 was just released, so you can use that one to create the 'Rule Packages' that are needed to run the GP tool.

There's also a second GP tool that directly creates a WebScene based on the ArcGIS scene. So basically, CityEngine is only needed to author the rules and create the RPK.

As long as the resulting pipelines are MultiPatches, you can also export them ( together with the buildings ) in a WebScene.

ok ?
