Smoothing Out the Surface of Meshes
Sometimes you want a smooth surface on a model so it makes a smooth,
shiny print. Meshlab's poisson filter will nicely smooth out your mesh.
If you are able to create a high resolution scan from ReconstructMe, you may
want to smooth it out a little for printing. For regular resolution Recon-
structMe scans, skip this step to keep more detail in the model.
Open Meshlab
Create a new project from File
→
New Empty Project.
Then select File
→
Import Mesh to open your STL file in Meshlab.
When the dialog box pops up that asks you if you want to Unify Duplica-
ted Vertices, click Ok.
Turn on layers
Go to the View menu in the top toolbar
→
Show Layer Dialog.
Apply the Poission Filter
Select Filters
→
Point Set
→
Poisson Filter
→
Surface Reconstruction Pois-
son. In the dialog box, set Ochre Depth to 11 (The higher number the
better; “good” is “11”). If you go any higher than 11, Meshlab may crash.
Click apply.
Hide hide the original mesh
After applying the poisson filter, there will be two layers: the original
(
Figure 9-24
), and one labeled Poisson Mesh.
Click on the green “eye” icon of the file name to hide the original file and
keep the Poisson mesh. You will see visible smoothing on the surface of
the model, as shown in
Figure 9-25
.
Save as a STL file
Go to File
→
Export Mesh As. Use the default export options.
