MapObjectPoseToOb jectSpace (XSIMath)

Description

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

Scripting Syntax

    XSIMath.MapObjectPoseToObjectSpace( ObjectSpace, Space, Pose )

C# Syntax

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

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.

Return Value

SITransformation (pose)

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;

    LogMessage ( "The translation of the cube relative to its parent: x " +
    oVec3.x + " y " + oVec3.y + " z " + oVec3.z );
    var oObjectTrans = XSIMath.MapObjectPoseToObjectSpace(oTransParent, oDestinationTrans, oTrans);
    oObjectTrans.GetTranslation(oVec3);
    LogMessage ( "The translation of the cube relative to the cone: x " +
    oVec3.x + " y " + oVec3.y + " z " + oVec3.z );
