XSIMath is an intrinsic object that provides basic 3D mathematics functionality. An intrinsic object is one that you can refer to by name in your code without creating an instance of it first. The scripting engine creates the XSIMath object when the engine is loaded. All of its methods and properties are available to your script at all times.

This object is designed to allow scripters to easily create Math objects, including SIVector3, SIMatrix3, SIMatrix4, SITransformation, SIRotation and SIQuaternion.

1. VBScript Example

Dim v3 
set v3 = XSIMath.CreateVector3(10.0, 10.0, 10.0)
v3.ScaleInPlace 2
Application.LogMessage join( v3.get2, ", " )
'Output:
'INFO : 20, 20, 20

2. JScript Example

var v3 = XSIMath.CreateVector3( 10.0, 10.0, 10.0 ) ;
v3.ScaleInPlace( 2 ) ;
Application.LogMessage( v3.x +", "+v3.y+", "+v3.z ) ;
//Output:
//INFO : 20, 20, 20

3. Python Example

#
# This example demonstrates how to create and manipulate an SIVector3
# object in Python.
#
Application.NewScene( "", False )
v3 = XSIMath.CreateVector3(10.0, 20.0, 30.0) 
v3.ScaleInPlace(2) 
x=y=z=0 
x, y, z = v3.Get(x,y,z) 
Application.LogMessage( '%(x).2f %(y).2f %(z).2f' % vars() ) 
# Output of above script:
#INFO : 20.00 40.00 60.00
