Get absolute/world coords of child node


I’d like get the world position of an “ray” object like LineSegs or CollisionSegment which is attached to a model however their methods (getPointA()/getPointB() for CollisionSegment or getVertex(n) for LineSegs) return only relative coordinates to its parent,

Please, could you guys indicate a solution for this?

Thanks in advance,

absolutePoint = render.getRelativePoint(parentNodeOfPoint, localPoint)

Thanks, rdb!
