I doubt that would make a difference. I just tried a bimodal distribution using 
two point sources, and the filter still executed in about the same amount of 
time.

So what version of ParaView are you using? Are you using a binary downloaded 
from paraview.org or did you build your own?

Subject: [EXTERNAL] Re: [Paraview] Delaunay 3D filter too slow

My points are not Uniform distribution.They take from intersections of 89 wefts 
and 180 warps.So the points are intensive at poles and sparse at equator.Is 
this the problem?

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.

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.

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.

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.

I have a lot of points taking sample from a solid sphere.So I want to use 
Delaunay 3D filter to render the shpere with known scalars of the points.But it 
took me so much time.What should I do?
