Function glm::ext::is_perpendicular

pub fn is_perpendicular<F: BaseFloat, T: GenFloatVec<F>>(x: T, y: T) -> bool

Returns true if vector x is perpendicular to y, i.e., angle between x and y is π/2.

Example

use glm::ext::is_perpendicular;

let x = glm::vec2(1., 0.);
let y = glm::vec2(0., 1.);
assert!(is_perpendicular(x, y));
