VisibilityRoadMap

Struct VisibilityRoadMap 

Source
pub struct VisibilityRoadMap { /* private fields */ }
Expand description

Visibility Road-Map planner.

Given polygon obstacles, the planner expands each obstacle vertex outward by expand_distance, connects all mutually visible vertices (including start and goal), and finds the shortest path via Dijkstra.

Implementations§

Source§

impl VisibilityRoadMap

Source

pub fn new(expand_distance: f64) -> Self

Create a new planner.

Source

pub fn plan( &self, sx: f64, sy: f64, gx: f64, gy: f64, obstacles: &[ObstaclePolygon], ) -> Option<(Vec<f64>, Vec<f64>)>

Plan a path from (sx, sy) to (gx, gy) avoiding obstacles.

Returns the path as (xs, ys) vectors, or None if unreachable.

Source

pub fn get_edges( &self, sx: f64, sy: f64, gx: f64, gy: f64, obstacles: &[ObstaclePolygon], ) -> Vec<((f64, f64), (f64, f64))>

Return the road-map edges for visualisation purposes.

Each entry is ((x1, y1), (x2, y2)) with i < j to avoid duplicates.
