geo-visibility

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.

```rust use geo::{Coordinate, Line}; use geo_visibility::Visibility;

let lines = [ Line::new( Coordinate { x: 0.0, y: 0.0 }, Coordinate { x: 1.0, y: 8.0 }, ), ];

let visibility_polygon = point.visibility(&lines); ```
