SITransformation

Object Hierarchy | Related C++ Class: CTransformation

Description

This object represents a transformation which is the result of the combination of a Scaling, a Rotation and a Translation, in the S.R.T order.

Examples

1. JScript Example

/*
   Example of how to use the SITransformation to read and write 
   the scaling, rotation and translation of an object
*/

var oNull = Application.ActiveSceneRoot.AddNull( "MyNull" ) ;

// Change the position and rotation of the null
// by providing a new transform

oNewLocalTransform = XSIMath.CreateTransform() ;

// Change posx, posy
oNewLocalTransform.PosX = 5; 
oNewLocalTransform.PosX = 6; 

// Set rotx to 180 degrees
oNewLocalTransform.RotX = 180;

// Scale y-axis (scly)
oNewLocalTransform.SclY = 2; 


oNull.Kinematics.Local.Transform = oNewLocalTransform ;


PrintTransformation( oNull.Kinematics.Local.Transform ) ;

// Show the "SRT: of a SITransformation object
function PrintTransformation( in_oTransform )
{
   var oVector = XSIMath.CreateVector3();

   in_oTransform.GetScaling( oVector ) ;
   PrintVector( "Scaling:", oVector ) ;

   // In Radians
   in_oTransform.GetRotationXYZAngles( oVector ) ;
   PrintVector( "Rotation:", oVector ) ;

   in_oTransform.GetTranslation( oVector ) ;
   PrintVector( "Translation:", oVector ) ;
}

// Print a vector.  Values are rounded to 3 decimal places
function PrintVector( in_Prefix, in_oVec )
{
   Application.LogMessage( in_Prefix + " " + 
          XSIRound(in_oVec.x,3) + ", " + 
          XSIRound(in_oVec.y,3) + ", " + 
          XSIRound(in_oVec.z,3) ) ;
}

// Output:
//INFO : Scaling: 1, 2, 1
//INFO : Rotation: 3.142, 0, 0
//INFO : Translation: 5, 6, 0

2. VBScript Example

dim transfo
set transfo = XSIMath.CreateTransform
Application.LogMessage TypeName(transfo)
