Object Model: SITransformation.GetRotationAxisAngle

SITransformation.GetRotationAxisAngle

Description

Extracts the axis and angle from the rotation part of this transformation.

Warning: This method doesn't work with scripting languages that don't support arguments passed by reference such as JScript. You must use SITransformation.GetRotationAxisAngle2 instead.

C# Syntax

SITransformation.GetRotationAxisAngle( SIVector3 io_pAxis, Object& io_pvarAngle );

Scripting Syntax

SITransformation.GetRotationAxisAngle( io_pAxis, io_pvarAngle );

Parameters

Parameter	Type	Description
io_pAxis	SIVector3	Axis of rotation
io_pvarAngle	Floating Point value	Angle of rotation (in radians)

Examples

VBScript Example

dim t1, axis
' Create transformation.
set t1 = XSIMath.CreateTransform
' Create 3D vector.
set axis = XSIMath.CreateVector3
'Do something on t1
t1.GetRotationAxisAngle axis, angle
