Meshlab 3D processing: Screened Poisson Reconstruction

[@logiclrd]

In the latest Meshlab versions, the filter has been renamed to: "Surface Reconstruction: Screened Poisson"

Is there a way to remove the flat part that forms behind and that closes well (in a rounded way)? Thank u!!!

[@Erpty05]

how about exporting the texture? How would you export a UV map of the color?

I know I'm late, but since this is the top comment, here's a solution: gist.github.com/shubhamwagh/0dc3b8173f662d39d4bf6f53d0f4d66b

Hello, Good job. How do you remove the edge whose length are greater than n*mean(length). So that the poisson reconstruction is closer to the original

How can I construct a mesh around the point cloud and have the 'back' result in a flat plane?

[@walterkonrad3054]

why don't smooth filters work properly after using screened-poisson?

[@camnyc9257]

My version of meshlab does NOT have this feature. It has “Surface Reconstruction: Poisson”, but that has different options and does not work for me. I’m here redirected by standard cyborg’s Capture app, trying to convert a point cloud 3D scan from their app to a mesh, no success so far.

did you find out? I'm also struggeling

I am trying to make my mesh water tight so I can calculate the volume. How do I stop mesh lab from generating geometry around my mesh when I use the Poisson reconstruction?

[@balajibbi]

I have the same problem. Please let me know if you find a solution.

Filters->Remeshing-> close holes; play around with the settings there. It's worked for me

use export in .PLY not obj

hi | am really beginner in this 3d modelling why do we use the poisson filtering could you answer

Grazie per il video (e per il programma disponibile gratuitamente!). Sto cercando di ricostruire la superficie di un terreno partendo da una nuvola di punti (sono i dati digitali del terreno messi a disposizione dalla regione Valle d'Aosta). Tuttavia quando provo ad utilizzare il filtro di cui parli nel video, ricevo un messaggio di errore che mi informa che i punti non hanno associata alcuna normale. Mi viene suggerito di flaggare l'opzione Pre-Clean; seguendo il suggerimento e applicando il filtro, però, il programma sembra cancellare tutti i punti e mi restituisce due layer (quello della mesh e quello originale della nuvola di punti) apparentemente vuoti. E' possibile sapere cosa/dove sbaglio? Grazie!

Come non detto....ho scoperto il filtro per i vertici che ne calcola le normali (Filters - Point Set - Compute normals for point sets). Dopodichè la mesh (superifice) è stata creata senza problemi. Adesso il tutto sta a capire come migliorarla. Comunque grazie ancora per l'ottimo strumento!

Hi there I'm here from the standard cyborg’s Capture app. I used the Screened Poisson Surface Reconstruction but an error pops up. "Filter requires correct per vertex normals. E.g. it is necessary that our ALL the input vertices have a proper, not-null normal. If you encounter this error on a triangulated mesh try to use the 'Remove Unreferenced Vertices' filter (usually unreferenced vertices on surfaces have null normals). Enabling the Cleaning option also works. I tried the Remove Unreferenced Vertices filter and it just deletes all the vertices. I don't know which cleaning option to use. I tried a bunch and they didn't do anything. Any suggestions? I'm trying to export this scan into an OBJ. Thanks

same here

Hi! I downloaded a .ply file instead and that worked fine. First I tried with .obj and that did not work. Then I exported it to .obj for my 3d software.

[@compassft]

I had the same exact problem. I solved by using this filter "Filters --> Point Set --> Compute normals for point sets" on the point cloud before applying the Poisson reconstruction filter. Hope this helps

[@elvaterhablante]

thanks for the explanation of the parameters, it really helps

Awesome! Thank you for this video!
