GlobalTransform
Methods
GlobalTransform es un solo lectura instantánea de un Node’s transformación en espacio mundial. Se obtiene mediante node.getGlobalTransform() y refleja la composición de la propia del nodo Transform con la transformación de cada ancestro hasta la raíz de la escena.
Todas las propiedades son de solo lectura. Para cambiar la posición de un nodo, modifica la local Transform en su lugar.

import com.aspose.threed.GlobalTransform;GlobalTransform no se instancia normalmente de forma directa; lo recibes de node.getGlobalTransform().
