Implementations§

source§

impl Point

source

pub fn from_xy(x: f32, y: f32) -> Point

Creates a new Point.

source

pub fn from_f32x2(r: f32x2) -> Point

Creates a new Point from f32x2.

source

pub fn to_f32x2(&self) -> f32x2

Converts a Point into a f32x2.

source

pub fn zero() -> Point

Creates a point at 0x0 position.

source

pub fn is_zero(&self) -> bool

Returns true if x and y are both zero.

source

pub fn is_finite(&self) -> bool

Returns true if both x and y are measurable values.

Both values are other than infinities and NaN.

source

pub fn normalize(&mut self) -> bool

Scales (fX, fY) so that length() returns one, while preserving ratio of fX to fY, if possible.

If prior length is nearly zero, sets vector to (0, 0) and returns false; otherwise returns true.

source

pub fn set_normalize(&mut self, x: f32, y: f32) -> bool

Sets vector to (x, y) scaled so length() returns one, and so that (x, y) is proportional to (x, y).

If (x, y) length is nearly zero, sets vector to (0, 0) and returns false; otherwise returns true.

source

pub fn length(&self) -> f32

Returns the Euclidean distance from origin.

source

pub fn set_length(&mut self, length: f32) -> bool

Scales vector so that distanceToOrigin() returns length, if possible.

If former length is nearly zero, sets vector to (0, 0) and return false; otherwise returns true.

source

pub fn set_length_from(&mut self, x: f32, y: f32, length: f32) -> bool

Sets vector to (x, y) scaled to length, if possible.

If former length is nearly zero, sets vector to (0, 0) and return false; otherwise returns true.

source

pub fn distance(&self, other: Point) -> f32

Returns the Euclidean distance from origin.

source

pub fn dot(&self, other: Point) -> f32

Returns the dot product of two points.

source

pub fn cross(&self, other: Point) -> f32

Returns the cross product of vector and vec.

Vector and vec form three-dimensional vectors with z-axis value equal to zero. The cross product is a three-dimensional vector with x-axis and y-axis values equal to zero. The cross product z-axis component is returned.

source

pub fn scale(&mut self, scale: f32)

Scales Point in-place by scale.
