  the value to divide the vector by

return the dot product of this vector and the passed one

Parameters

  other vector

return true if this vector is equal to the given values or vector

Parameters

• Rest...args:
  | [number, number]
  | [number, number, number]
  | [number]
  | [Vector2d ]
  | [Vector3d ]
  | [ObservableVector3d ]

  other vector or vector components

Floor the vector values

Floor this vector values

return the length (magnitude) of this vector

return the square length of this vector

Linearly interpolate between this vector and the given one.

Parameters

• v: Vector3d | ObservableVector3d

  other vector

• alpha: number

  distance along the line (alpha = 0 will be this vector, and alpha = 1 will be the given one).

Update this vector with the maximum value between this and the passed vector

Parameters

• v: Vector2d | Vector3d | ObservableVector3d

  other vector

Update this vector with the minimum value between this and the passed vector

Parameters

• v: Vector2d | Vector3d | ObservableVector3d

  other vector

interpolate the position of this vector on the x and y axis towards the given one by the given maximum step.

Parameters

• target: Vector2d | Vector3d | ObservableVector3d

  other vector

• step: number

  the maximum step per iteration (Negative values will push the vector away from the target)

Negate the vector values

Negate this vector values

normalize this vector (scale the vector so that its magnitude is 1)

change this vector to be perpendicular to what it was before.
(Effectively rotates it 90 degrees in a clockwise direction around the z axis)

project this vector on to another vector.

Parameters

• v: Vector2d | Vector3d | ObservableVector3d

  The vector to project onto.

Project this vector onto a vector of unit length.
This is slightly more efficient than project when dealing with unit vectors.

Parameters

• v: Vector2d | Vector3d | ObservableVector3d

  The unit vector to project onto.

Revokes the proxy object, preventing further access to the ObservablePoint instance.

Parameters

• angle: number

  The angle to rotate (in radians)

• Optionalv: Vector2d | Point

  an optional point to rotate around (on the same z axis)

Parameters

• x: number

  x component

• Optionaly: number = x

  y component

• Optionalz: number = 1

  z component

Multiply this vector values by the passed vector

Parameters
