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 ... View more

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. ... View more

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) ... View more

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...) ...

Hi Ulf Silbersky First and foremost: Intel Iris Pro Graphics is not officially supported. Please refer the latest official hardware requirements: CityEngine 2015 system requirements—Esri CityEngine | ArcGIS for Desktop CityEngine is designed on cross platform standards to provide the customers a choice between different hardware and operating systems. This means, there is nothing fundamentally prohibiting CityEngine from running on this hardware. There might even be official support in the future. So, if any users come across issues on this hardware, please report them here ... View more

Hello Christopher, Thank you for reporting this issue. For system testing I use similar system: CPU Type - Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz Graphics Chipset - AMD Radeon (TM) R9 200 Series Windows Version - Windows 8.1 I tried to reproduce the issue with: Radeon Software Version - 15.11 Radeon Software Edition - Crimson and had no issues. Do you use special settings in your driver? Your help is very appreciated! ... View more

Hello Gjin P A CityEngine scene can have a Scene Coordinate System (SCS) set with a unit of measurement assigned. By default the SCS is set to CityEngine CS, the default CityEngine coordinate system. Generated CGA models are in CityEngine CS without any forced unit of measurement. In general cga scripts use meters. CityEngine CS is used to write out FBX meshes there is no option to set the unit of measurement. If on Autodesk 3ds max FBX Import Centimeters is displayed, please set the scale factor to 1.0. This should give the right scale for System Unit Meters. ... View more

Hi Felix, There is no easy way to tilt crossings and streets that are going parallel to slopes. I recommend to align the terrain to the street network to make the scene look good. Please refer the CityEngine help on the topic: Aligning Street Networks to the Terrain ... View more

chandrasekhar reddy guda wrote: Matthias Buehler i am also having the same problem, normals problems getting when importing drawing file, please share a code of .net Hello Chandra Sekhar Reddy Guda, There is no need to write .net code, in fact CityEngine does not use .net at all. Instead you can use CityEngine CGA modelling language to manipulate the imported shapes from a drawing file. The cga rule snipped above provided by Matthias Buehler can be used to reverse any down facing normals. Further information can be found in the CityEngine CGA Help: reverseNormals Operation As a second option, you can use the CityEngine python scripting interface. This python script corrects the shapes normals after import: # checks if the shape point order is clockwise # note: applies to horizontal plane (x: east, y: up, z: south) def clockwise(shape):     shapeVertices = ce.getVertices(shape)     sum = 0     for i in xrange(0,len(shapeVertices),3):         x1 = shapeVertices         z1 = shapeVertices[i+2]         x2 = shapeVertices[(i+3)%len(shapeVertices)]         z2 = shapeVertices[(i+5)%len(shapeVertices)]                         sum += (x2-x1)*(z2+z1)     return sum < 0 if __name__ == '__main__':       selectedShapes = ce.selection()     for shape in selectedShapes:         if ce.isShape(shape):             # ensure counter-clockwise order of input shapes (normal up)             if clockwise(shape):                 ce.reverseNormals(shape) Further information can be found in the CityEngine Python Help: Python Scripting Interface Reference ...

Hi Phil, thank you for your question and welcome to GeoNet! When providing a set of coordinates (Lat/Long) to Google Street View, the Image API returns an image of a location from which the coordinates are visible. Here is a description how to obtain exact camera coordinates (Lat/Long) of the received panorama image: https://developers.google.com/maps/documentation/javascript/streetview#StreetViewServiceResponses​ To align a CityEngine scene to a street view panorama you need to define a new camera in the Camera Menu. The CityEngine Help gives a description on how to set the camera parameters. CityEngine Help Cameras Here is how to define the values: Angle of View Zoom level 1 (default) correspondents roughly to a 90° field of view https://developers.google.com/maps/documentation/javascript/streetview#TilingPanoramas horizontal Position (X,-Z)The geographical coordinates of the camera center have to be first transformed into the chosen cartesian scene coordinate system. http://cehelp.esri.com/help/topic/com.procedural.cityengine.help/html/manual/georef/scs.html As a final step they have to be converted to get CityEngine coordinates with y-up, meters representation http://cehelp.esri.com/help/topic/com.procedural.cityengine.help/html/manual/georef/vcs.html vertical Position (Y) The exact camera height of the panorama is usually not provided. Typically it is about 2.5m / 8 ft above street level. The Elevation of the street level at the camera position in CityEngine coordinates can be obtained from the Navigation Display by pointing the mouse on the street. Rotation X defines the Lateral axis (pitch) rotation Y defines the Vertical axis (yaw) rotation Z defines the Longitudinal (roll) rotation (typically 0) Distance to Point of Interest this value can be set to 1 in order to make small corrections in rotation. ...
