SIRotation.GetAxisAngle2

Description

Extracts the axis and angle from this rotation (ordered the same as SIRotation.GetAxisAngle).

Note: This method must be used with scripting languages that don't support arguments passed by reference such as JScript. For more information on getting output arguments, see About Output Argument Arrays.

C# Syntax

Object SIRotation.GetAxisAngle2( SIVector3 io_pAxis );

Scripting Syntax

oFloat = SIRotation.GetAxisAngle2( axis );

Return Value

Floating point value containing the angle of rotation (in radians)

Parameters

Parameter Type Description
axis SIVector3 Softimage will fill in the vector with the axis of rotation

Examples

JScript Example

var r1 = XSIMath.CreateRotation();
r1.SetFromXYZAnglesValues( 
		XSIMath.DegreesToRadians( 90 ), 
		XSIMath.DegreesToRadians( 45 ), 
		0 ) ;
var axis = XSIMath.CreateVector3();
var angle = r1.GetAxisAngle2( axis );
Application.LogMessage( "Axis: " + axis.x +","+ axis.y +","+ axis.z );
Application.LogMessage( "Angle: " + XSIMath.RadiansToDegrees( angle ) );
//Output:
//INFO : Axis: 0.8628562094610168,0.3574067443365933,-0.35740674433659325
//INFO : Angle: 98.42105811814942
