<p>Let me add a possible answer: Do you think it might be worthwile
to try compiling Paraview with Mesa on Windows (version 7)? As it
seems that the "native" OpenGL support is not really stable with
the latest driver - is there a chance that going through Mesa 3D
would improve the situation? Or is it even impossible, so I should
better not even bother trying?</p>
<p>Thanks for any helpful hint!</p>
<p>I mean: It is possible to do some limited working with a
"ticklish software" that tends to crash regularly (first of all:
always save everything immediately!), but it is not really so much
fun...<br>

<div dir="auto">A little after a couple of days: It turns out that
while the display is now complete, the program behaves now
rather "ticklish" Doing too much of zooming, panning etc with a
large model leads to crushes of the graphics driver (the message
says explicitly!), the PV prog window becomes completely white
and the program does not react any more; has to be killed with
the task manager.

all,</span>
<div style="font-size:12.8px"><br>
</div>
<div style="font-size:12.8px">With some
self-written plugin I am generating rather
large "unstructured grids". With a model
with something more than 700'000 blocks I
realized that on my Lenovo notebook I did
not get a complete display of all the
blocks, so I made tests with subsets of the
data. It turns out that with less than 1000
blocks everything works fine, with 20'000
blocks there are already some "reductions"
and finally with the full model even more:
see the attached Powerpoint with screenshots
(plus details about my system and the
Paraview version).</div>
<div style="font-size:12.8px"><br>
</div>
<div style="font-size:12.8px">My question is
now if there is possibly some kind of
"graphic card overflow" happening? I could
so far not test the software with the same
model on another computer.</div>
<div style="font-size:12.8px"><br>
</div>
<div style="font-size:12.8px">And whatever the
reason is: is there something that I can do
about it?</div>
<div style="font-size:12.8px"><br>
</div>
<div style="font-size:12.8px">It is to say
that the unstructured grid is a bit
"unconventional" by the fact that often
adjacent blocks do not have common edges and
points, sharing thus only common partial
faces. With this one possibility would be
that Paraview cannot properly carry out
certain optimizations that are relying on
the fact that neighbor blocks "normally"
(??) share a face, edges and points. However
I do not know whether this is an issue or
not!? In this case it might be an option to
change the entire data set to a set of just
cubes that happen to touch each other.</div>
