<div dir="ltr">Hi Andreas,<div><br></div><div>There are still multiple levels of ghost cells. The difference is that they are no longer marked by their level. Rather, we are using that unsigned char / cell to encode other information (as a bit field). This works because algorithms are no longer required to strip the ghost level they requested. Rather, the removal now happens at the end of the pipeline. It is still possible for consumers to request multiple ghost levels and for sources to produce them. Note that the only sources that really support this are the structured data sources and filters like D3.</div><div><br></div><div>Best,</div><div>-berk</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Sep 14, 2015 at 5:08 AM, Andreas Buykx <span dir="ltr"><<a href="mailto:A.Buykx@tnodiana.com" target="_blank">A.Buykx@tnodiana.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal"><span lang="EN-US">I have read the kitware blog post about the change in handling of ghost levels in VTK6.3.0, and I understand that there are no longer multiple levels of ghost cells. However there is still the vtkStreamingDemandDrivenPipeline
key UPDATE_NUMBER_OF_GHOST_LEVELS that is being updated throughout the pipeline. Could you please explain how this key is related to the new ghost-level behavior?
