D3DXMatrixRotationX function (D3DX10Math.h)

Note

The D3DX10 utility library is deprecated. We recommend that you use DirectXMath instead.

Builds a matrix that rotates around the x-axis.

Syntax

D3DXMATRIX* D3DXMatrixRotationX(
  _Inout_ D3DXMATRIX *pOut,
  _In_    FLOAT      Angle
);

Parameters

pOut [in, out]

Type: D3DXMATRIX*

Pointer to the D3DXMATRIX structure that is the result of the operation.

Angle [in]

Type: FLOAT

Angle of rotation in radians. Angles are measured clockwise when looking along the rotation axis toward the origin.

Return value

Type: D3DXMATRIX*

Pointer to a D3DXMATRIX structure rotated around the x-axis.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixRotationX function can be used as a parameter for another function.
