Implementations§

source§

impl Orientation2D

source

pub fn point_is(self, origin: Point2D<Px, Px>, point: Point2D<Px, Px>) -> bool

Check if point is orientation from origin.

Returns true if the point is hit by a 45º frustum cast from origin in the direction defined by the orientation.

source

pub fn box_is(self, origin: Box2D<Px, Px>, b: Box2D<Px, Px>) -> bool

Check if b is orientation from origin.

Returns true if the box b collides with the box origin in the direction defined by orientation. Also returns true if the boxes already overlap.

source

pub fn search_bounds( self, origin: Point2D<Px, Px>, max_distance: Px, spatial_bounds: Box2D<Px, Px>, ) -> impl Iterator<Item = Box2D<Px, Px>>

Iterator that yields quadrants for efficient search in a quad-tree, if a point is inside a quadrant and passes the Orientation2D::point_is check it is in the orientation, them if it is within the max_distance it is valid.
