Description 描述
Representation of four-dimensional vectors.
This structure is used in some places to represent four component vectors (e.g. mesh tangents, parameters for shaders). In the majority of other cases a Vector3 is used.
Static Properties
| negativeInfinity | Shorthand for writing Vector4(float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity). | ||
| one | Shorthand for writing Vector4(1,1,1,1). | ||
| positiveInfinity | Shorthand for writing Vector4(float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity). | ||
| zero | Shorthand for writing Vector4(0,0,0,0). |
Properties 属性
