SIRotation.Quaternion

SIRotation.Quaternion

導入

v5.1

詳細

この回転の SIQuaternion を設定したり、戻したりします(クォータニオンは自動的に作成されます)。

C#構文

// get accessor

SIQuaternion rtn = ISIRotation.Quaternion;

// set accessor

ISIRotation.Quaternion = SIQuaternion;

JScript の例

/*

	This example demonstrates how to use Quaternion property to return the quaternion of the rotation 

	as an SIQuaternion (without having to explicitly create it first) as well as how to set a new quaternion.

*/

var oRot = XSIMath.CreateRotation();

// The Quaternion property takes care of creating oQuat as an SIQuaternion

var oQuat = oRot.Quaternion;

// Now set w, x, y and z normalize properties of the quaternion and then save it back onto the rotation

oQuat.Set(0.5, 0.5, 0.5, 0.5);

oRot.Quaternion = oQuat;

// Get a new quaternion

var oQuatDest = oRot.Quaternion;

Application.LogMessage( " The w,x,y,z quaternion values of this rotation are: " 

		+ oQuatDest.W + " " + oQuatDest.X + " " + oQuatDest.Y + " " + oQuatDest.Z );

// Expected results:

//INFO :  The w,x,y,z quaternion values of this rotation are: 0.5 0.5 0.5 0.5
