Crate geo_visibility[−][src]
This crate contains algorithms to compute visibility polygon.
This code is a Rust port of the C++ lib visibility.
Example
The following example shows how to compute the visibility polygon of a point amongst line obstacles.
The visibility
method is provided by the Visibility
trait which is implemented for most geo-types.
use geo::{Coordinate, Line}; use geo_visibility::Visibility; let point = geo::Point::new(0.0, 0.0); let lines = vec![ Line::new( Coordinate { x: 1.0, y: 1.0 }, Coordinate { x: 1.0, y: -1.0 }, ), Line::new( Coordinate { x: -1.0, y: -1.0 }, Coordinate { x: -1.0, y: -2.0 }, ), ]; let visibility_polygon = point.visibility(lines.as_slice());
