UnsafeNativeMethods.Plane.DotCoordinate Method

Language:

Computes the dot product of a plane and a 3-D vector. The w parameter of the vector is assumed to be 1.

Note: For programming in Microsoft Visual Basic .NET or Microsoft JScript .NET, use the equivalent method in the Microsoft.DirectX structures.

Definition

Visual Basic Public Shared Function DotCoordinate( _
    ByVal pPlane As Plane, _
    ByVal pV As Vector3 _
) As Single

C# public static float DotCoordinate(
    Plane pPlane,
    Vector3 pV
);

C++ public:
static float DotCoordinate(
    Plane pPlane,
    Vector3 pV
);

JScript public static function DotCoordinate(
    pPlane : Plane,
    pV : Vector3
) : float;

Visual Basic	Public Shared Function DotCoordinate( _ ByVal pPlane As Plane, _ ByVal pV As Vector3 _ ) As Single
C#	public static float DotCoordinate( Plane pPlane, Vector3 pV );
C++	public: static float DotCoordinate( Plane pPlane, Vector3 pV );
JScript	public static function DotCoordinate( pPlane : Plane, pV : Vector3 ) : float;

Parameters

pPlane Microsoft.DirectX.Plane
Source Plane structure.

pV Microsoft.DirectX.Vector3
Source Vector3 structure.

Return Value

System.Single
A Single value that is the dot product of the plane and the vector.

Remarks

Given a plane (a, b, c, d) and a 3-D vector (x, y, z) the return value of this function is a*x + b*y + c*z + d*1. The DotCoordinate method is useful for determining the plane's relationship with a coordinate in 3-D space.
