Drew, thank you for the reply. My tests with World Creator have shown, that it may help to convert the 16bit Tiff from grey-scale to RGB. For data with 16bit per channel, an image tool that can handle this bit depth is required. If there is no 16bit editing support, most of the tools will downsample the data to 8bit on import.

Hello Drew, can you please provide additional information on the DEM regarding: image format (tiff,png,..) bit depth (8,16,32) number of channels (grey-scale (1), RGB (3), RGB + transparency (4))

Hello Anete, What is the exact error message you receive? In the message above "[1905.2194, 2139370.5, 1209.4117]" hints, that the problem is in the y-direction (this means up in the CityEngine native coordinate system). Did you try to import the FileGeodataBase into an empty CityEngine scene? Is the error then still occurring?

Hi Aida, I'm answering on behalf of Eric and Cheryl. Unfortunately the facade wizard of version 2015.0 is affected by a bug, that does not show the texture. Please upgrade to the latest version (2015.2) to use the facade wizard. Sorry for your extra effort. Thomas

Dear Nirdesh Singh, CityEngine can export models in the KML format. KMLs store location data in the geographic WGS84. 3D models are also stored in the COLLADA interchange file format. Models | Keyhole Markup Language | Google Developers If that is not suitable for you needs, than the XML file structure of the could be extended by adding additional tags. This can be achieved by a python callback function called for each shape after generation. http://cehelp.esri.com/help/index.jsp?topic=/com.procedural.cityengine.help/html/manual/python/python_scripting03.html But of course this is an customization that does not adhere to the Collada specification.

Dear NIrdesh Singh, CityEngine only allows projected coordinate systems (PCS) as scene coordinate systems. Coordinate System Dialogs For importing base maps, it is important to know, that CityEngine does not support re-projection. Therefore the imported raster data needs to be in the same coordinate system as your scene. Importing Georeferenced Data Best practice for CityEngine is to use a national grid or UTM as scene coordinate system.

Hello Lahmer Belkacem Thank you for the data. I had a look at the DEM TIF you provided. The issue is, that it uses a geographical coordinate system for georeferencing. Unfortunately CityEngine only supports Cartesian coordinate systems for terrain layers. Please export the DEM again using "WGS 1984 UTM Zone 31N" coordinates (same as OSM file) for georeferencing. City Engine Help: Importing Georeferenced Data "No reprojection nor rotation is applied to image data on import. The image's coordinate system is used only as reference system for location, extent and unit (translate and scale transformation) for the image data during import. It is therefore important to have image data ready in the target coordinate system before importing into CityEngine." Thomas F

Could you please provide a use case for your feature request? The CityEngine team knows some special use cases, where this can make sense, but we are still collecting more... The C++ SDK can only provide a fraction of the CE python functionality, but here it is easier to open it up the externals IDEs.

Hi André, Thank you for this qestion. In default graph drawing mode, one wants the terrain be smothed to align to the network graph. But you are using a premodeled bridge as a base for the graph. This means the feature has to be deactivated. Settings for new streets can be controlled by using the Street Creation Settings dialog. To open the dialog, choose Graph → Street Creation Settings... from the main menu. There you have to uncheck the "Align terrain" option. For more details please refer the CityEngine Help on that topic: Creating and Editing Street Networks Manually Best regards

Dear Jamal, for more information on using CityEngine to create Web Scenes, please refer the following tutorial: Tutorial 15: Publish web scenes—CityEngine Tutorials | ArcGIS for Desktop best Thomas

Hi Tim, Thank you for your comprehensive feedback! Based on your insights I have created users stories for futher improving the feature. I now understand that for your work, you need very high accuracy in shadow analysis. This means that the 3D models casting the shadows, also have to be very exact. Please understand that for CityEngine there was a decision made to only offer moth accuracy. I know, that in order to be more accurate the day and even the year (leap year effects, precession and nutation of the earth, ...) need to be considered.

Hi Tim, Thank you for your report. Have you tried to update to a newer driver version? Maybe your problems are linked to this known issue: CE crashes on machines with ATI graphics cards

Scene Light is defined by solar elevation and azimuth. The most important factors to determine these values are: Geo Location (long, lat) Time (morning, noon, evening) corresponding Time Zone Month (on northern hemisphere June for max and December for min elevation) For most analysis the shortest (June) and longest (December) shadows over the course of a day are relevant. In this two months solar elevation and length of a day are not varying much from day to day. So for simplification the exact day can be neglected.

Thank you Alexis for the reproduction case. Today I filed a bug report. The workaround would be to use lowercase image file endings (e.g. *.jpg instead of *.JPG)

Hi Kenneth Lindhardt, Thank you for your report. For CityEngine 2015.2 the original issue of this thread has been fixed. So I couldn't reproduce what you described. Here is what I did: create a new project (Menu > File > New... > CityEngine project) add a image file to the assets folder (via drag and drop) select the image file in the navigator then open the crop tool (right click > Crop image... or Menu >Shapes > Crop image...)
