In this project we propose a highly controllable automatic method to synthesize plausible hiking networks connecting the different points of interest on a real or synthetic terrain. Our approach relies on a geometry graph generation algorithm based on a non-Euclidean metric combined with a path finding algorithm to generate a hiking network containing trails with different grades of difficulty. Unlike previous work, our method does not require a specific path merging stage, instead, each path generated takes into account the existing paths and merges with them if the conditions allow it. The trajectory of the trails is based on the different parameters of the scene, including the slope of the terrain, the exposure to falling, the natural obstacles such as lakes or snowy regions and the already existing trails.
