Description

Converts a position described in WorldSpace to a position in a different ObjectSpace.

Scripting Syntax

XSIMath.MapWorldPositionToObjectSpace( ObjectSpace, Position )

C# Syntax

SIVector3 XSIMath.MapWorldPositionToObjectSpace( SITransformation in_pObjectSpace, SIVector3 in_pPosition );

Parameters

Parameter	Type	Description
ObjectSpace	SITransformation	ObjectSpace in which we want to convert the position.
Position	SIVector3	Position to convert.

Return Value

The new SIVector3 position.

Examples

VBScript Example

set oRoot = Application.ActiveProject.ActiveScene.Root  
set oCube = oRoot.AddGeometry("Cube","MeshSurface")  
oCube.Kinematics.Global.Parameters("posy").value = 4.0  
oCube.Kinematics.Global.Parameters("posx").value = 2.0  
oCube.Kinematics.Global.Parameters("rotx").value = 30  

set oTrans = oCube.Kinematics.Local.Transform  
set oPos = XSIMath.CreateVector3( 1.0, 1.0, 1.0)  

set oObjectPos = XSIMath.MapWorldPositionToObjectSpace(oTrans, oPos)  
Application.LogMessage "The position (1,1,1) is (" & oObjectPos.X & "," & oObjectPos.Y & "," & oObjectPos.Z & ") in the cube object space"  
set mynull = oCube.AddPrimitive("Null")

mynull.Kinematics.local.Parameters("posx").value = oObjectPos.x  
mynull.Kinematics.local.Parameters("posy").value = oObjectPos.y  
mynull.Kinematics.local.Parameters("posz").value = oObjectPos.z
