SetFromXYZAngleValues (SIQuaternion)

Introduced

3.5

Description

Sets the quaternion using X,Y,Z Euler angles (in radians).

Scripting Syntax

SIQuaternion.SetFromXYZAngleValues( x, y, z )

C# Syntax

SIQuaternion.SetFromXYZAngleValues( Double in_dX, Double in_dY, Double in_dZ );

Parameters

Examples

JScript Example

   // Define 2 quaternion orientations using degrees radian
   var qA = XSIMath.CreateQuaternion();

   qA.SetFromXYZAngleValues( 
       XSIMath.DegreesToRadians(0),
       XSIMath.DegreesToRadians(0),
       XSIMath.DegreesToRadians(90) );

   var qB = XSIMath.CreateQuaternion();

   qB.SetFromXYZAngleValues( 
       XSIMath.DegreesToRadians(0),
       XSIMath.DegreesToRadians(0),
       XSIMath.DegreesToRadians(180) );

   // Do a sperical linear interpolation 50% between A & B 
   // and log results.
   var qC = XSIMath.CreateQuaternion();

   qC.Slerp( qA, qB, 0.5 );

   Application.LogMessage( "Q[" + 
       qC.w + "," +
       qC.x + ", V(" + 
       qC.y + "," + 
       qC.z + ")" + 
       "]" );
          
   var aXYZ = new VBArray(qC.GetXYZAngleValues2()).toArray();
   Application.LogMessage( "R(" + 
       XSIMath.RadiansToDegrees(aXYZ[0]) + "," +
       XSIMath.RadiansToDegrees(aXYZ[1]) + "," + 
       XSIMath.RadiansToDegrees(aXYZ[2]) + ")" );
