Microsoft DirectX 9.0 SDK Update (October 2004)

UnsafeNativeMethods.Vector3.TransformCoordinateArray Method

Language:

Note: This documentation is preliminary and is subject to change.

Transforms array (x, y, z, 1) by a given matrix, and projects the result back into w = 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 .NET Public Shared Function TransformCoordinateArray( _
    ByVal pOut As Vector3, _
    ByVal outStride As Integer, _
    ByVal pSource As Vector3, _
    ByVal vectorStride As Integer, _
    ByVal pSourceMatrix As Matrix, _
    ByVal count As Integer _
) As Vector3
C# public static Vector3 TransformCoordinateArray(
    Vector3 pOut,
    int outStride,
    Vector3 pSource,
    int vectorStride,
    Matrix pSourceMatrix,
    int count
);
Managed C++ public: static Vector3 TransformCoordinateArray(
    Vector3 pOut,
    int outStride,
    Vector3 pSource,
    int vectorStride,
    Matrix pSourceMatrix,
    int count
);
JScript .NET public static function TransformCoordinateArray(
    pOut : Vector3,
    outStride : int,
    pSource : Vector3,
    vectorStride : int,
    pSourceMatrix : Matrix,
    count : int
) : Vector3;

Parameters

pOut Microsoft.DirectX.Vector3. A Vector3 structure that represents the results of the method.
outStride System.Int32. Stride between vectors in the output data stream.
pSource Microsoft.DirectX.Vector3. Source Vector3 structure array.
vectorStride System.Int32. Stride between vectors in the input data stream.
pSourceMatrix Microsoft.DirectX.Matrix. Source Matrix structure.
count System.Int32. Number of elements in the array.

Return Value

Microsoft.DirectX.Vector3 . A Vector3 structure that is the result of the method.

Remarks

This method transforms all vectors in the pSource parameter by the matrix pSourceMatrix, projecting the result back into w = 1.

The return value for this method is the same value returned in the pOut parameter. Resultantly, the TransformCoordinateArray method can be used as a parameter for another method.
