I was talking about Python event listeners. I don't really have experience with this, it's just something that one of my coworkers set up quite some time ago to check some things. Rather a hack, of course. But yes, you need CE started ( the GUI ). There's no way around this. You could try the same thing with ArcGIS, using the CityEngine GP tool, would that be an option ? ( basically aggregating the data in ArcGIS and generate the geometries in there ) m. ... View more

Hi, this is currently not possible. you need to run an instance of CityEngine for these tasks. would be nice of course. the closest thing possible for this is to run an instance of CE and work with listeners. ok ? matt ... View more

I'm not sure if I can follow perfectly. In a 'typical' CityEngine project, the user starts with the terrain, then aligns the shapes to the terrain. Where the elevation data originally comes from does not matter, as long as it's imported into CityEngine as a raster image. Means CityEngine currently only supports 'heightmaps' as terrains, no TINs or LIDAR or Esri Grids. [ I've created most rules for the Honolulu dataset, so I know the project quite well. ] Let me know if there's more questions ! Matt ... View more

Hi .. Guess who did about 80% of that playable city in that siggraph video .. :cool: The demo we created there was with Unity. What realtime environment are you working with ? Lemme know .. m. ... View more

sure.. just check based on scope.sx and scope.sz, geometry.area() and geometry.isConcave. that way, in CGA, you can classify what type of footprints you have, then link to different rules for that typology. usually, classifying on shape area, scope width and depth is enough. makes sense or do you need more input ? m. ...

hi, what do you mean by .. I was just able to pass the information individually ending up not overlapping with the ground and the buildings. can you post an image ? matt ... View more

Hi, the best approach is inded using the assetBestSize / assetBestRatio / operations. note that s(0,0,0) before the i() operation insert with the original asset size. this is used to not scale the asset at all. maybe also check out the Example 'Instanced City', this uses those operations, but scales the buildings. otherwise, what you can do is use assetInfo() and create a series of splits that check the dimensions of the empty lots and insert the buildings by using splits. hope this gives some inputs .. m. ...

Hi, There's plenty of tutorials and tutorial videos and other training resources available, where you can learn these basics. Please check them here: http://forums.arcgis.com/threads/64843-CityEngine-Collection-RESOURCES-FAQ-HELP This will get you started ! Matt ... View more

Hi ! What happens if you run the connection test ? (see image) Lemme know .. m. [ATTACH=CONFIG]29461[/ATTACH] ... View more

Hi, This is currently not possible, no. This is a current limitation of CGA. 1] I'd align the terrain to shapes - you may have seen how that works in a tutorial 2] Since a shape can only sample once per model, each subshape during model generation can not sample the DEM again, thus you also can not subdivide the shape or add more points to then drape the shape on the DEM better. 3] The only thing you can do is do it in 2 steps:    a] use one CGA rule that cuts your shape into smaller pieces *    b] when this model is generated, select it, right-mouse-click > convert Models to Shapes    c] use the alignShapesToTerrain tool to align those shapes to the DEM    d] use your rule to make the transparent models. * e.g.: attr mySize= 3 @StartRule Lot -->     alignScopeToAxes(y)     split(x) {~mySize: split(z) {~mySize: SmallerShapes. }* }* ok ? ...

Hi, What I wanted to say is there's the most obvious error in your code: attr BldgTypeCu ="" the attribute BldgTypeCu is of the type 'string', an empty string. In case Colorby == "BldgTypeCu": you are comparing Colorby with a string of the value 'BldgTypeCu' (the word itself), not the actual value of the attribute 'BldgTypeCu'. You need to remove the quote signs. 🙂 Sorry for the confusion .. :rolleyes: ok ? m. ... View more

Hi, CityEngine only supports rectangular, raster-based terrains. In the upcoming version, 2013, we'll treat differently ( not black ). 🙂 m. ... View more

hi, Shapes can not be transparent. Only Models can be transparent. Shape + rule -> Generate -> Model. So if you still see grey, then you still see the shape. Hide the visibility of shapes via the F11 key or the according button in the toolbar. ok ? matt ... View more
