D3DXQUATERNIONROTATIONYAWPITCHROLL function
Create a four-dimensional number of rotation with a Y-axis angle, a x-axis angle and a z-axis angle.
definition:
D3DXQUATERNION * WINAPI D3DXQUATERNONROTATIONYAWPITCHROLL (
D3DXQUATERNION * Pout,
Float YAW,
Float Pitch,
Float roll
);
Parameters
pout
[IN, OUT] points to the operation result of the D3DXQUATERNION structure.
YAW
[IN] Whenesses the Y-axis rotation angle (unit radians).
Pitch
[IN] around the X-axis rotation angle (unit radians).
Roll
[IN] Whenesses the Z-axis rotation angle (unit radians).
return value:
Point the four-component number of the rotation of the D3DxQuaternion structure.
Description:
The function return value is the same as the POUT parameter. This allows the function D3DXQUATERNIONROTATIONYAWPITCHROLL as a parameter of other functions.
