Struct RiverNetwork 

pub struct RiverNetwork {
    pub segments: Vec<RiverSegment>,
    pub flow_grid: Grid2D,
    pub threshold: f32,
}

Complete river network.

Fields

segments: Vec<RiverSegment>

flow_grid: Grid2D

Flow accumulation grid.

threshold: f32

River threshold (cells with flow > this are rivers).

Implementations

impl RiverNetwork

pub fn is_river(&self, x: usize, y: usize) -> bool

Check if a cell is a river.

pub fn width_at(&self, x: usize, y: usize) -> f32

Get river width at a cell.

pub fn mouths(&self, heightmap: &Grid2D, sea_level: f32) -> Vec<(usize, usize)>

Find river mouths (river cells adjacent to ocean).

pub fn longest_river(&self) -> Vec<(usize, usize)>

Find the longest river path.
