Thank you for your feedback. 3 days is really a long time Can you please give more information on how the trees in your scene are composed. As I understand you added extra leafs to a pine tree model. This means you inserted the same OBJ many times, right? I would like to recreate the behavior. You can export your data to a variety of different 3D formats: General Export Reference There is not option to extract the database from a cej. If you want to remove a project from your CityEngine workspace, please refer the CityEngine help on Exporting a Project . ... View more

Hello Lixin Huang 'MipMapping' and 'Texture Compression' can be disabled in the CityEngine preferences (Preferences > General > GrammarCore). Update: The location has changed to: Preferences >General > Procedural Runtime > Rendering ... View more

Hello Emmanuel John, Thank you for your question. You can continue to use your CityEngine 2015 workspace. It gets automatically updated on first startup. The same applies to the ESRI.lib content. The scenefiles (CEJ) get converted at load. Saving the scene then creates CEJs in the new version. Can you please give more details on what is not working in CityEngine? ... View more

Hello Z R In the "Prefetching Data" step the scenefile gets loaded. Normally this is quite fast and model generation takes most of the time. But as you are mentioning, your scene is made with an older version of CE. Therefore conversion of legacy data might be needed at startup. Once the scene is loaded, you could save it in the new format and try if opening is now faster. If there is no change, another way of narrowing down the problem is, to remove layers and save/re-load the scene until the prefetching step is faster. ... View more

Hello Phil Your project sounds very interesting. Regrettably the CGA grammar definition can not be published to external users. Of course you can use the CGA reference to derive your own version. ... View more

Hello Amber, In the CityEngine, buildings are described using the CGA grammar. A CGA rule file consists of several rules that define how the actual building geometry is created. A CGA rule file is usually assigned to a shape (e.g., a lot or a street etc.). One of the rules defined in the file is then chosen to be the shape's start rule, i.e., generation will start with this rule. So for example: The rule file would be building.cga and the start rule is a rule named Lot within this file. For further information, please refer the CityEngine help on Rule Files ... View more

Hi Amber, Welcome to the CityEngine community! Your approach with the 5m DTM seems to be feasible.

Update: The exporters for CityEngine 2015.2 do include atlas generation functionality. Texture Settings: Create Texture Atlas Creates texture atlases which combine a set of textures into one, thus reducing the number of textures and materials. All textures except COLORMAPs are removed. Note: in case of repetition (i.e. uv coordinates outside [0,1]), textures can not be put into an atlas. ... View more

Hello Tanvi Maheshwari, Thank you for your report. I tested CityEngine 2015.2 for the issue you described, but was unable to reproduce. Selecting shapes in the viewport was accurate on the external monitor. Here is my setup: MacBook Pro (Retina, 15 inch, Mid 2014) OS X 10.10.5 (Yosemite) Monitor with 2560 x 1440 native resolution (extended display) Could you please provide more information on your system?

Hi Sean, to solve your task, please use the geometry.isRectangular (geometry Functions) function. Synopsis bool geometry.isRectangular(float tolerance) Parameters tolerance The tolerance in degrees for deciding if an angle is a right one or not. Returns true if all faces of the current shape's geometry consist of 4 vertices and contain only right angles, false otherwise. Angles in the range [90-tolerance, 90+tolerance] are considered to be "right". ... View more

Hello Tianfang, Thank you for your report. Can you please specify, what exactly happens when you import the DEM as an Terrain into a CityEngine scene? Is there any error message displayed? For texturing the DEM a second image file is used. For an example please see the attached image. ... View more

Hello, Thank you for your request. Regarding attribute search, there is no more functionality than described in the corresponding help section: Use CityEngine Web Viewer—ArcGIS Online Help | ArcGIS So please make sure, that all the classification the user might need (like "FLOORCOUNT < 2") is added as an attribute, before exporting the web scene. Since there is no official support for a "proper DB query", the only way is hosting the Web Viewer yourself and modify the search code. But this needs extensive programming knowledge. 42471 - Host 3D Web Scenes ... View more

Hi Tim, Sorry to hear you had to change your hardware. The CityEngine team is committed to support ATI hardware. So it would be very helpful to us, to get the scene, that creates the crash on opening. ... View more
