Vec

Sets the the x and y components of this vector.

Copies x and y components into this vector from v.

Transforms this vector by the affine matrix affineMatrix.

Use this when transforming a Vec that represents a point or position.

Transforms this vector by the affine matrix affineMatrix, ignoring translation.

Use this instead of affineTransform() when transforming a Vec that represents a normal or a tangent.

Transforms this vector.

vec.transform({
  position: Vec(1, 2),
  rotation: 45,
  scale: Vec(1, 0.5), // Scale can also be a number
  skew: 10,
  origin: Vec(0, 0), // The center of rotation and scale
})

Adds the vector v to this vector.

Adds the scalar x to both components of this vector.

Subtracts the vector v from this vector.

Subtracts the scalar x from both components of this vector.

Multiplies this vector by the vector v.

Multiplies both components of this vector by the scalar x.

Divides this vector by the vector v.

Divides both components of this vector by the scalar x;

Multiplies both components of this vector by -1. This is functionally the same as .mulScalar(-1).

Tests if this vector exactly equals the vector v.

Rounds the components of this vector to the next-lowest integer.

let v = Vec(3.141, -1.618);
v.floor();
// Result: Vec(3, -2)

Rounds the components of this vector to the next-highest integer.

let v = Vec(3.141, -1.618);
v.ceil();
// Result: Vec(4, -1)

Rounds the components of this vector to the closest integer.

let v = Vec(3.141, 3.618);
v.round();
// Result: Vec(3, 4)

Compares the components of this vector and v and sets this vector's to the lesser of the two.

let a = Vec(1, 4);
let b = Vec(2, 3);
a.min(b);
// Result: Vec(1, 3)

Compares this vector's components to x and sets them to the lesser of the two.

let v = Vec(1, 2);
v.minScalar(3);
// Result: Vec(1, 2)

Compares the components of this vector and v and sets this vector's to the greater of the two.

let a = Vec(1, 4);
let b = Vec(2, 3);
a.max(b);
// Result: Vec(2, 4)

Compares this vector's components to x and sets them to the greater of the two.

let v = Vec(1, 2);
v.maxScalar(3);
// Result: Vec(3, 3)

Linearly interpolates this vector to the vector v by the mixing factor t.

Scales this vector so that its length is equal to 1.

Note the this vector must already have a non-zero length.

Rotates this vector clockwise by an angle specified in degrees.

Rotates this vector clockwise by an angle specified in radians.

Rotates this vector clockwise by exactly 90°.

This is functionally the same as writing vec.rotate(90) but is computationally simpler.

Rotates this vector counter-clockwise by exactly 90°.

This is functionally the same as writing vec.rotate(-90) but is computationally simpler.

The vector projection of this vector onto a non-zero vector v, (also known as the vector component or vector resolution of a in the direction of b), is the orthogonal projection of this onto a straight line parallel to v.

A trivial closest point implementation to maintain a uniform interface with Geometry.

Sets this vector to a unit-length vector at angle.

Sets this vector to a unit-length vector at angle.
