Object Model: XSIMath.MapObjectPoseToObjectSpace

XSIMath.MapObjectPoseToObjectSpace

Description

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

C# Syntax

SITransformation XSIMath.MapObjectPoseToObjectSpace( SITransformation in_pObjectSpace, SITransformation in_pSpace, SITransformation in_pPose );

Scripting Syntax

oReturn = XSIMath.MapObjectPoseToObjectSpace( ObjectSpace, Space, Pose );

Return Value

SITransformation (pose)

Parameters

Parameter	Type	Description
ObjectSpace	SITransformation	ObjectSpace in which the pose is described.
Space	SITransformation	Space in which we want to convert the pose .
Pose	SITransformation	Pose to convert.

Examples

1. JScript Example

var oRoot = Application.ActiveProject.ActiveScene.Root;
var oCube = oRoot.AddGeometry("Cube","MeshSurface");
oCube.Kinematics.Global.Parameters("posy").value = 4.0;
oCube.Kinematics.Global.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.Local.Transform;
var oTransParent = oCube2.Kinematics.Global.Transform;
var oVec3 = XSIMath.CreateVector3();
oTrans.GetTranslation (oVec3);
var oDestinationTrans = oCone.Kinematics.Global.Transform;
