Model Integration

Our results are for now mostly visual. We have integrated the vegetation into the 3D model of Strasbourg city center (but this could be done with any map). With the help of the autorefine function we dont have any trees in the buildings. We can also see that the trees are well placed in the streets and that the vegetation is well integrated into the 3D model.

Higher Levels of Detail (LOD) are visually more appealing but also require significantly more time to generate and are more complex to manage due to the increased number of faces in the mesh. For instance, in the Republic Square area of Strasbourg, 110 trees in LOD 3 results in a vegetation mesh with 14,349,087 faces and a file size of approximately 3.7 GB. In contrast, LOD 0 for the entire city center, which includes 3,100 trees and 1,558,331 faces, is only around 400 MB.
