Struct RotatedRect 

pub struct RotatedRect { /* private fields */ }

An oriented rectangle.

This is characterized by a center point, an “up” direction indicating the orientation, width (extent along axis perpendicular to the up axis) and height (extent along up axis).

Implementations

impl RotatedRect

pub fn new( center: PointF, up_axis: Vec2, width: f32, height: f32, ) -> RotatedRect

Construct a new RotatedRect with a given center, up direction and dimensions.

pub fn contains(&self, point: PointF) -> bool

Return true if a point lies within this rotated rect.

pub fn expanded(&self, dw: f32, dh: f32) -> RotatedRect

Return a copy of this rect with width increased by dw and height increased by dh.

pub fn corners(&self) -> [PointF; 4]

Return the coordinates of the rect’s corners.

The corners are returned in clockwise order starting from the corner that is the top-left when the “up” axis has XY coordinates [0, 1], or equivalently, bottom-right when the “up” axis has XY coords [0, -1].

pub fn edges(&self) -> [LineF; 4]

Return the edges of this rect, in clockwise order starting from the edge that is the top edge if the rect has no rotation.

pub fn center(&self) -> PointF

Return the centroid of the rect.

pub fn up_axis(&self) -> Vec2

Return the normalized vector that indicates the “up” direction for this rect.

pub fn width(&self) -> f32

Return the extent of the rect along the axis perpendicular to self.up_axis().

pub fn height(&self) -> f32

Return the extent of the rect along self.up_axis().

pub fn area(&self) -> f32

Return the signed area of this rect.

pub fn resize(&mut self, width: f32, height: f32)

Set the extents of this rect. width and height must be >= 0.

pub fn intersects(&self, other: &RotatedRect) -> bool

Return true if the intersection of this rect and other is non-empty.

pub fn from_rect(r: RectF) -> RotatedRect

Return a new axis-aligned RotatedRect whose bounding rectangle matches r.

pub fn orient_towards(&self, up: Vec2) -> RotatedRect

Return the rectangle with the same corner points as self, but with an up axis that has a direction as close to up as possible.
