<div>That is strange. I cannot replicate your problem. I used a point source to create 16020 random points in a sphere, and the Delaunay triangulation took only about 2 seconds. My processor might be a bit better than yours, but not anywhere near enough to
explain the difference.</div>

<div>What version of ParaView are you using? Are you a binary downloaded from <a href="http://paraview.org" target="_blank">paraview.org</a> or did you build your own?</div>

<div dir="ltr">in fact,I have only 16020 points for test.My cpu is AMD Athlon(tm) II P320 Dual-Core Processor with 2.1GHz.How long will it take in this case if I use one cpu to calculate?I have wait for more than 10 minutes before stopping it.</div>

<div>Your options are probably either to wait or do something else. Delaunay triangulation is a pretty heavyweight operation and in general it is not trivial to impose a topology on a collection of points.</div>
</div>
</div>

</div>
<div>You might rethink whether you really need to create a solid sphere in the first place. I'm guessing you have at least around 100,000 points (or else Delaunay probably would not be that slow). If you just render these points as a cloud of points, you should
get enough occlusion for it to look pretty much like a sphere.</div>
