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
