Cityengine Roof Texture How To Obtain The

In order to realize that the roof texture called by each building is the image of the top of it, the author has prepared a solution for readers. However, in the 'CityEngine City Modeling New Selection', the roof texture of each building uses the entire image, which brings great inconvenience to the use of data. : //wenku.it168.com/d_000565555.shtml. In fact, in the 'CityEngine New Modeling for City Modeling' in the Demo Theater of the 2012 User Conference, there is a related introduction to this problem. Group('Texture Selection',2) Order(1) attr UpperfloorsTexture getUpperfloorsTexture Order(2) attr GroundfloorTexture getGroundfloorTexture Constants: const LibraryLocation 'Facades/International' const NeighborLookup 20 number of neighboring textures in the folder to look up to find a texture which fits well to the building heightForeword For some time, a friend has been asking questions about how to obtain the roof texture from the image.

Material textures can then be specified for either flat or sloped roof form. Released CityEngine 2020, Simon Haegler and Taisha Fabricius from Esri.Programmed roof styles can be chosen from a custom dropdown menu. Set the colormap to builtin:uvtest.png, which is a texture to quickly check UV coordinates.Data preparation and data requirements Through the introduction of 'CityEngine City Modeling New Selection', we learned that the roof texture acquisition is related to coordinates, so the building bottom data and the corresponding building roof coordinates on the image should be consistent, that is, to meet the following Two requirements:VES New York Presents: Common VFX workflows with CityEngine and Houdini (Webinar). The UV coordinates will be projected along the scopes xy plane and repeated every 2.25 units in x and every 1.5 units in y direction.

Data import: copy the adjusted vector file to the data folder, copy and store the cut image folder to the assets folder, copy the original image file to the maps folder (the three folders are all stored in the new Under the project directory) 3. Engineering and scene creation: ' - 01 Basic Tutorial ' has a detailed introduction, which will not be repeated here.2. See the following result after cutting:At the same time, after processing, the vector data will add the following internal fields on the basis of the original attribute fields:Combined with the content in 'CityEngine New Modeling for Urban Modeling', we know that with this information we can adjust the previous rules to achieve the image texture mapping of the roof.Project creation and rule adjustment 1. In order to simplify the corresponding workflow, Here we make a GP tool (this tool is not available in ArcGIS 10.0 and previous versions) , and its interface is as follows:Enter the vector data and the original image of the bottom of the building separately, and then select the output path (folder) and click OK to run to get the result (the running time will be relatively long when the amount of data is large).

Therefore, when doing rule-based modeling, it is necessary to combine ArcGIS data processing and rule requirements, as well as industry standards and rule writing, so that the rule-based model is more meaningful. Using rules to generate a three-dimensional model, this time we will get the scene effect of the roof texture and the image coordinated as follows:As a modeling software and a rule-based modeling software, CityEngine requires a lot of data processing to provide basic data and attribute information. Adjust the original rules: the adjusted results as follows (not in building walls textures focus on paper) 5.
