## Topics

### Operators

[`static func + (Vector3D, Vector3D) -> Vector3D`](/documentation/Spatial/Vector3D/+(_:_:)-7gbcj)

Returns a vector that’s the element-wise sum of two sizes.

[`static func += (inout Vector3D, Vector3D)`](/documentation/Spatial/Vector3D/+=(_:_:))

Adds two vectors and stores the result in the left-hand-side variable.

[`static func - (Vector3D, Vector3D) -> Vector3D`](/documentation/Spatial/Vector3D/-(_:_:)-6zam)

Returns a size that’s the element-wise difference of two vectors.

[`static func -= (inout Vector3D, Vector3D)`](/documentation/Spatial/Vector3D/-=(_:_:))

Subtracts a vector from a vector and stores the difference in the left-hand-side variable.
