pub fn is_ccw_turn(p1: [f64; 2], p2: [f64; 2], p3: [f64; 2]) -> bool

Check if three points make a counterclockwise turn

Arguments

• p1 - First point [x, y]
• p2 - Second point [x, y]
• p3 - Third point [x, y]

Returns

• true if the turn is counterclockwise, false otherwise

Examples

use scirs2_spatial::convex_hull::algorithms::graham_scan::is_ccw_turn;

let p1 = [0.0, 0.0];
let p2 = [1.0, 0.0];
let p3 = [0.0, 1.0];

assert!(is_ccw_turn(p1, p2, p3));
