Subregion graph: A path planning acceleration structure for characters with various motion types in very large environments

Abstract: Modern computer graphics applications commonly feature very large virtual environments and diverse characters which perform different kinds of motions. To accelerate path planning in such a scenario, we propose the subregion graph data structure. It consists of subregions, which are clusters of locally connected waypoints inside a region, as well as subregion connectivities. We also present a fast algorithm to automatically generate a subregion graph from an enhanced waypoint graph map representation, which al… Show more

“…The work by Pettré et al [68] creates a navigation graph that is suitable for multi-layered terrains. It fist computes a roadmap of the static environment In the work by Wardhana et al [97], they generate navigation graphs by computing relevant way points and then creating transitions between those way points based on whether the character can move between them. One of the main advantages of their method is the ability to handle a variety of movement for the characters, such as walking, jumping or flying.…”
