Think of the color palette as the starting point for your coloring scheme, and from there you can add and remove colors from the lookup table at will. For this reason, we don't keep the value you choose for color palette in the drop-down box, because as soon as you adjust the lookup table, that palette name would no longer match the lookup table you're using. Since the default color palette is "Cool to Warm", you don't notice any change when you choose that one again. And since your data arrays have a numeric range of 0, you should just see blue. If you change the color palette to "Red to Blue Rainbow", in your case, you will see the data become all red, though the color palette drop-down will not change.</div><div> </div><blockquote style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex;"><div><div><div><div><div dir="ltr" style="color:rgb(0,0,0);background-color:rgb(255,255,255);"><div dir="ltr"><span style="font-size:13px;"></span></div><div dir="ltr"><span style="font-size:13px;">Also there is always latency between user inputs and </span><span style="color:rgb(34,34,34);font-family:arial, sans-serif;font-size:12.8px;">visualization.

In that case, there is potentially a bug in the geometry exporter.</div><div><br clear="none"></div><div> Regarding the stl file issue, I did follow the same steps to build ParaViewWeb which you provided (just using hardware rendering rather than OSMesa) and I see the same issue you described. So in this case, it seems like maybe some commit since the 4.4 release has fixed an issue with the stl reader. If you are able to get the latest master and build it, that could fix your stl loading problem.</div><div><br clear="none"></div><div>Hope this helps.</div><div><br clear="none"></div><div>Cheers,</div><div>Scott</div><div><br clear="none"></div></div><div><br clear="none"><div>On Fri, Sep 25, 2015 at 12:45 PM, kai liu <span dir="ltr"><<a rel="nofollow" shape="rect" ymailto="mailto:liuwukai@yahoo.com" target="_blank" href="mailto:liuwukai@yahoo.com">liuwukai@yahoo.com</a>></span> wrote:<br clear="none"><blockquote style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex;"><div><div><div><div><div><div style="color:rgb(0,0,0);"><span style="font-size:13px;">Dear Scott:</span></div><div style="color:rgb(0,0,0);font-size:13px;"><br clear="none"></div><div style="color:rgb(0,0,0);font-size:13px;">Thank you for the testings.</div><span></span><div style="color:rgb(0,0,0);font-size:13px;"><br clear="none"></div><div style="color:rgb(0,0,0);font-size:13px;"> </div><div style="color:rgb(0,0,0);font-size:13px;">1) Regarding using local rendering on the cube data file: It seems that with local rendering, we may not properly handle coloring by arrays where the data range is 0 (e.g. the range of T in your case was <span style="font-size:14px;line-height:20px;">[303.1499938964844, 303.1499938964844]).
