Settlement Topology with Trees

Following the previous post I could easily add a rotation element to the buldings so they always faced the road. Adding trees is relatively easy and I de-conflicted them from the building by creating a set of bounding spheres and checking for their intersect.


By creating a a set of parallel vertexes to describe the path line I am able to apply a texture blended across the path to prevent a hard edge.ParallelPathLines.jpg


I make the settlement base texture slightly different from the surround so I can spot it easily in the landscape – I need to do a bit more work to make it segue into the standard textures.
