Hadrien, I’m not sure what you mean by the “area” of points. As I’m sure you know, particles are 0D elements and themselves have no area to speak of. As you said, you can use the glyph operation to create a surface around each point, but the surface area in that case is simply the surface area of the sphere size you chose times the number of points.
You’ve asked if you can project the points onto an existing mesh surface. I don’t know of an easy way to do that, but let’s put that problem aside for a moment. Assuming you could, what good would that do? Points on a surface are still just points. The surface area of your mesh (nasal cavity) will be the same surface area regardless of how many points are in it and where they are. Can you more precisely describe what it is you are trying to measure? -Ken (By the way, the ParaView team has been transitioning from using this mailing list to using a tool called discourse to ask questions and archive results.

From: ParaView [mailto:paraview-boun...@public.kitware.com] On Behalf Of hadrien calmet Sent: Tuesday, September 25, 2018 8:04 AM To: paraview@public.kitware.com Subject: [EXTERNAL] [Paraview] point to surface Hi every one I have a list of point (coordinate x,y,z), using table to point I can visualize it on PV. But I would like to know the total area of those points. So I tried glyph (sphere, all the points) than integrate variable and I obtained the area. But the area is depending of the radius that I put on glyph parameter. those points are the deposition of particles in a complex geometry(human nasal cavity) They are calculated when they intersect the surface mesh of the nasal cavity. my question: There is a way to "project" those points on the mesh surface (then filtering and integrate variable to calculate the total area) ? thank you Hadrien Calmet Dpt.
