Hello,
I am trying to understand the XDMF file format to import my own files
into ParaView. Let's say I have the following 16 XYZ points:
12.3500 95.1900 20.00
27.2600 60.2600 33.00
38.6000 69.5200 33.00
60.2000 -152.3300 93.00
-15.9600 26.0800 33.00
-17.8400 168.0900 61.00
13.8000 -90.7300 59.00
6.8400 -73.0700 163.00
-15.6200 26.3200 33.00
-31.2100 58.7200 10.00
38.8100 -27.7800 10.00
51.1500 -129.8700 10.00
3.4900 126.7200 54.00
24.0500 121.7200 65.00
-13.4700 166.7500 60.00
3.1100 -79.3700 33.00
with intensity values:
5.10
5.30
4.20
4.20
4.10
4.80
4.60
4.70
4.20
5.00
7.20
4.40
5.00
4.00
5.10
4.20
How do I get these to points to be displayed as a 3d scatter plot in
ParaView with the intensity values changing the color of each point? I
made some attempt at an xdmf file but it currently only shows a single
white dot. The "Information" tab in paraview recognizes all 16 points
and seems to know where they should be (creates good axises), but only
the first one is being displayed. Attached is my attempt. I'm guessing
it's something to do with the "dimensions" attribute and whether or not
there should be spaces, tabs, or new lines between each value for the
topology. These aspects very much confuse me.
Thanks,
David Zemon
