I’ve talked about trees in CityEngine before, but not in any great detail. The fact is 3D urban models look really dull without a few trees and plants. Come to think of it so does the real-world!
I know the ESRI.Lib has a Plants directory and an amazing list of trees all in ‘Model’, ‘Analyical’, and ‘Fan’ 3D model types. The Plant_Loader.cga and Plant_Distributor.cga I consider one of the most useful rule files for users in CityEngine, simply because it saves us time. However it is quite North American in its approach and I’ve always meant to add to it with some ‘tweaks’ to reflect how I work and how I train others in my CityEngine courses.
So I’ve started a new project in CityEngine! It is the start of a British specific tree species rule file, I’ve adapted a list of the British tree species (native and non-native) from the Woodland Trust.
I’ve made simple small steps at first and I’ve started at the interface (inspector pane in the CityEngine interface). I’ve used the ESRI.Lib as a basis for an approach but obviously I want ‘British’ tree species.
After the overall structure of the interface and how it gets 3D assets to use is settled I will start trying to source 3D assets that represent these species. That’s the difficult bit for each species Esri has done 3 models (model, analytical, and fan). Whether I can finish this on my own is doubtful, so I will be adding this soon to my Github account and hoping others can help. Now, I’m not a big user of Github at all but it seems a good place to do this.
Feel free to contact me directly if you want more information or better yet want to help!
