In this case the sphere source just makes its local section of the sphere mesh, but in the same way parallel aware readers know what files or data portions they are responsible for. Regardless of the pipeline, in the end the vtkCompositedSynchronizedRende<wbr>rer and Window make sure that all ranks run at the same time and that, unlike in the other examples you found, the compositer depth composites the results and gathers them to rank 0 for display.<br><br><br><br></div></div>
