Thanks for the kind words ! Yes, you can do these things, but you need to do them in CGA. E.g. BlockShape -->     split(x) { '0.5: Half. | ~1: Half. } Matthias Buehler Head of 3D Technologies twitter: @MattB3D ----------------------------------- Garsdale Design Limited [email protected] www.garsdaledesign.co.uk ...

Hi ! Yes, thinks like this are possible .. Can you post a few pictures of what you imagine ? Let me know .. Matt Matthias Buehler Head of 3D Technologies twitter: @MattB3D ------------------------------------- Garsdale Design Limited [email protected] www.garsdaledesign.co.uk ... View more

Hey ! Try this: Rename the current workspace you are using, so when CE starts, it cannot find it and gives you the switch workspace dialog. create a new one. if possible. If it's not a workspace issue, close CE, go into the CityEngine app (right-click on app, Show Contents), then search for the '.cityengine' metadata folder and delete it. you may need to make invisible files visible. e.g. http://ianlunn.co.uk/articles/quickly-showhide-hidden-files-mac-os-x-mavericks/ Matthias Buehler Head of 3D Technologies twitter: @MattB3D ...

heya ! So you get this 'null pointer exception' every time you try to import the terrain ? And the file looks fine ArcMap ? (Since you talk about 'DEM' I assume you have access to GIS software ..) If so, that would be a file that needs to go to tech support .. [email protected] Let me know..

Hi .. Do you get any entries in the Log Window ? If so, what do they say if you double click them ? Matthias Buehler Head of 3D Technologies twitter: @MattB3D ... View more

Hey .. I helped them create this tutorial.. Maybe drop them a mail and check if something has changed for your current CE version .. Ok ?

Hi, First of all, to export models, you don't need to generate them. e.g. just select a shape and go to the exporter. The model does not need to exist in the viewport. CityEngine regenerates the model anyway new in the background for export. You're rather clogging export resources resources when having all displayed. For exports of big datasets, set Java memory (ini file) to about 50% system memory and run ONLY CityEngine. Close all other apps that may interfere with the process. After export, set the value back to something reasonble. [Or just leave CE closed.] Then it depends on the target application. I also wanted to write about dealing with this instead e.g. in Unity as an example in my last post, but left it out. I sadly never had time to solve this myself, but game engines provide solutions or plugins for this that just dynamically load models based on the player proximity to a specific model. e.g. if a model's bounding box is visible, load the model.. As said, I don't know the details. This then leads to the question of file granularity, where I'd say it's best to export 1 file per shape, which then can be loaded by the target app, e.g. Unity. I also assume that you may need to export at least 2 files for each shape: 1 with just the bounding box to check, which files should be loaded, and then 1 file for each LOD that gets triggered again based on proximity. I'd be really interested in seeing a solution for this. We can collaborate on this, if you like. 😉 About 2 years ago, I searched a bit and found a plugin ( never tested it ) that does 'asset streaming' (harddrive or cloud), which would be exactly what you need.

Hey Alexandru, The above inputs should help you code it. Note: You'll also need to write some sort of timer that runs all the time unless you want to trigger the update manually each time. Which may slow down the whole thing quite a bit, if you're constantly rebuilding all models. In general, especially when coding, I never display all models at the same time. But it depends on a use case. Remember, CityEngine is a modeling tool and not a visualization environment.. Regarding visualizing the whole Paris model fully generated: That does not really generate many polygons (in the default state, there, only a few buildings have the high LOD set), thus a good graphics card can display it quite easily. And the fluidity of the viewport is independent of the system RAM. If you have lots of textures, VRAM may have a bit of an impact, but mostly, it's the amount of polygons and especially shadows/ambient occlusion. Ok ?

Hi, Do NOT assign more than half of your system memory to Java. This memory is reserved by CityEngine and no other application can access it. If you still get 'out of memory / purge' messages, you'll need to get more RAM. I'd recommend 16 GB. Ok ?

Hi .. if you write a short specification on what precise behavior you need, we can send it to Zurich, to the dev team's wishlist.

Hi, I don't know the rules by heart, so I cannot comment on the changes .. The easiest is to stop the rule execution step by step to see what each line of code does, with a '.' (dot) at the right points. when you have found the rule that cuts up the street shape, add your additional split code in there. I assume that's what you try .. what's not working ? something specific ?

Hey Alan ! Cool work ! Keep' em coming ! You are right, CE can be used for so much more than just buildings .. 😉 Matthias Buehler Head of 3D Technologies twitter: @MattB3D --------------------------------- Garsdale Design Limited [email protected] www.garsdaledesign.co.uk ... View more

Hi .. Do you mean in the 'language' sense of translation ? Currently, a few things are supposed to be translated by the browser itself, but as far as I know, there's no 'localization' (language adaption) planned. Does that answer your question ?
