D3DXMatrixRotationAxis Function

Builds a matrix that rotates around an arbitrary axis.

Syntax

D3DXMATRIX *D3DXMatrixRotationAxis(      

    D3DXMATRIX *pOut,
    CONST D3DXVECTOR3 *pV,
    FLOAT Angle
);

Parameters

pOut

[in, out] Pointer to the D3DXMATRIX structure that is the result of the operation.

pV

[in] Pointer to the D3DXVECTOR3 structure that identifies the axis angle.

Angle

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

Return Value

Pointer to a D3DXMATRIX structure rotated around the specified axis.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixRotationAxis function can be used as a parameter for another function.
