D3DXMatrixRotationAxis

Builds a matrix that rotates around an arbitrary axis.

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 arbitrary axis. See D3DXVECTOR3.

Angle

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

Return Values

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.

Requirements

Header: Declared in D3dx9math.h.
