## XSIMath.MapObjectOrientationToObjectSpace

### Description

Converts an orientation described in an ObjectSpace to an orientation in a different ObjectSpace.

### C# Syntax

    SIVector3 XSIMath.MapObjectOrientationToObjectSpace( SITransformation in_pObjectSpace, SITransformation in_pSpace, SIVector3 in_pOrientation );

### Scripting Syntax

    oReturn = XSIMath.MapObjectOrientationToObjectSpace( ObjectSpace, Space, Orientation );

### Return Value

SIVector3 (orientation)

### Parameters

Parameter | Type | Description
--- | --- | ---
ObjectSpace | SITransformation | ObjectSpace in which the orientation is described.
Space | SITransformation | Space in which we want to convert the orientation.
Orientation | SIVector3 | Orientation to convert.

### Examples

#### 1. JScript Example

    var oRoot = Application.ActiveProject.ActiveScene.Root;

    var oCube = oRoot.AddGeometry("Cube","MeshSurface");

    oCube.Kinematics.local.Parameters("posy").value = 4.0;

    oCube.Kinematics.local.Parameters("posx").value = 2.0;

    var oCube2 = oCube.AddGeometry("Cube","MeshSurface");

    oCube2.Kinematics.Global.Parameters("posz").value = 3.0;

    oCube2.Kinematics.Global.Parameters("rotx").value = 45.0;

    var oCone = oRoot.AddGeometry("Cone", "MeshSurface");

    oCone.Kinematics.Global.Parameters("posy").value =  -2.0;

    oCone.Kinematics.Global.Parameters("posz").value = 90.0;

    var oTrans = oCube.Kinematics.global.Transform;

    var oOri = XSIMath.CreateVector3();

    aNormal = new VBArray( oCube.ActivePrimitive.Geometry.Facets.NormalArray );

    oOri.x = aNormal.getItem(0,1);

    oOri.y = aNormal.getItem(1,1);

    oOri.z = aNormal.getItem(2,1);

    var oDestinationTrans = oCone.Kinematics.Global.Transform;

    var oObjectOri = XSIMath.MapObjectOrientationToObjectSpace(oTrans, oDestinationTrans, oOri);

    Application.LogMessage  ("The second face of the cube normal vector represented in the cone referential "

    				+ XSIMath.RadiansToDegrees(oObjectOri.X) + "," + XSIMath.RadiansToDegrees(oObjectOri.Y)

    				+ "," + XSIMath.RadiansToDegrees(oObjectOri.Z) + " in the cube object space");

    // Expected results:

    //INFO : The second face of the cube normal vector represented in the cone referential

    //			0,-57.29577951308232,0 in the cube object space
