Interface VectorHelpers

Functions for manipulating vectors. It is Loosely based off of SkV3 in SkM44.h but Skia also has SkVec2 and Skv4. This combines them and works on vectors of any length.

interface VectorHelpers {
    add(a: VectorN, b: VectorN): VectorN;
    cross(a: Vector3, b: Vector3): Vector3;
    dist(a: VectorN, b: VectorN): number;
    dot(a: VectorN, b: VectorN): number;
    length(v: VectorN): number;
    lengthSquared(v: VectorN): number;
    mulScalar(v: VectorN, s: number): VectorN;
    normalize(v: VectorN): VectorN;
    sub(a: VectorN, b: VectorN): VectorN;

Methods

add

add(a: VectorN, b: VectorN): VectorN
Adds 2 vectors together, term by term, returning a new Vector.
Parameters

- b: VectorN
Returns VectorN
- Defined in canvaskit.d.ts:4240

cross

cross(a: Vector3, b: Vector3): Vector3
Returns the cross product of the two vectors. Only works for length 3.
Parameters
- a: Vector3
- b: Vector3
Returns Vector3
- Defined in canvaskit.d.ts:4247

dist

dist(a: VectorN, b: VectorN): number
Returns the length(sub(a, b))
Parameters
- a: VectorN

Returns number
- Defined in canvaskit.d.ts:4254

dot

dot(a: VectorN, b: VectorN): number
Returns the dot product of the two vectors.
Parameters
- a: VectorN
- b: VectorN
Returns number
- Defined in canvaskit.d.ts:4261

length

length(v: VectorN): number
Returns the length of this vector, which is always positive.
Parameters
- v: VectorN
Returns number
- Defined in canvaskit.d.ts:4267

lengthSquared

lengthSquared(v: VectorN): number
Returns the length squared of this vector.
Parameters
- v: VectorN
Returns number
- Defined in canvaskit.d.ts:4273

mulScalar

mulScalar(v: VectorN, s: number): VectorN
Returns a new vector which is v multiplied by the scalar s.
Parameters

sub

sub(a: VectorN, b: VectorN): VectorN
Subtracts vector b from vector a (termwise).
Parameters
- a: VectorN
- b: VectorN
Returns VectorN
- Defined in canvaskit.d.ts:4293
