<div dir="ltr"><div><div><div>Adam,<br><br></div>The color difference can be explained by the default coloring mode introduced recently (before the git tag version you tested with). Multiblocks are now automatically colored by blocks. Toggle the Color Legend and see the coloring array, "vtkBlockColors" is selected wereas in previous version it was Solid Color I guess.<br></div>Regarding the missing pieces, I can tell that with the same git version and with the OpenGL backend 1 (the old), all pieces are correctly drawn. What is specific is that this missing blocks (the data has like a global gemetry block + all the internal pieces) are the last block if the first level block hierarchy. <br><br></div><div>Joachim<br></div><div><div><div><br></div></div></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><b>Joachim Pouderoux</b><br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><font size="1"><i>PhD, Technical Expert</i></font><br><b><font size="1"><a href="http://www.kitware.fr" target="_blank">Kitware SAS</a></font></b><br></blockquote>

Indeed for a complicated geometry I see significant speed up (e.g. ~25 fps with OpenGL2 vs. 5 fps with regular ParaView). But I also see serious errors in the display. I've attached two images of our "g-2 muon storage ring" (never mind what it actually is, though it is very cool :-) ..<div><br></div><div><img src="cid:ii_14ee0923186dc321" alt="Inline image 1" height="252" width="412"></div><div><br></div><div>The first, mostly blue image, is from regular ParaView (downloaded Mac binary 4.3.1 64 bit) and is what the ring is supposed to look like. There is a color vector selected and I've unchecked "Map scalars" so that the colors are "true". And indeed the RGB color values in the vector are what is shown on the display. </div><div><br></div><div><br></div><div><img src="cid:ii_14ee0940516ed9bc" alt="Inline image 2" height="252" width="412"><br></div><div>The next image, with a chunk on the left side missing, is from the OpenGL2 ParaView (Mac built from source 4.3.1-882-gbdceec7 64 bit) configured identically as the other ParaView. So it should look identical to the mostly blue picture. Along with the missing chunk, you see the colors look very wrong. What's even stranger is that the missing chunk is really missing - not invisible - the visualization is made of multiblock datasets, and right clicking where a structure should be only brings up the link camera option. </div><div><br></div><div>You can try this yourself -- see <a href="https://www.dropbox.com/sh/900ocfc90v0w3r6/AACmqz8kVrGPUMnJbpxAFOzBa?dl=0" target="_blank">https://www.dropbox.com/sh/900ocfc90v0w3r6/AACmqz8kVrGPUMnJbpxAFOzBa?dl=0</a> . The "gm2ring.zip" file has gm2ring.vtm (with the corresponding gm2ring directory) and gm2ring.pvsm to restore my configuration.</div><div><br></div><div>I'm looking forward to using the OpenGL2 version when it works better. I hope this helps in working out its kinks (or hoping to find out I've built or configured something incorrectly). Let me know how I can help!
