MapObjectOrientationToObjectSpace (XSIMath)

Description

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

Scripting Syntax

XSIMath.MapObjectOrientationToObjectSpace( ObjectSpace, Space, Orientation )

C# Syntax

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

Parameters

Return Value

SIVector3 (orientation)

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
