I'm currently facing the following problem: I'm trying to use some objects for
which I have data in the form of stl and obj files within a simulation
program. In order for the simulation to work the simulation program must be
able to recognize that the stl/obj files describe a solid (consistent face
orientation, no holes). However, typically the meshes of the models are broken
in the sense that they have small holes for example. I found the nice meshlab
tool (very nice user interface by the way!) and tried to use it to heal the
meshes and fill the holes they have but it seems that meshlab crashes
everytime I use the healing operations. So I wonder if I'm missing something
or if the operation is somehow to complicated. You can reproduce the problem
using the following model: http://groups.csail.mit.edu/graphics/classes/6.837
You can do the following:
Import the mesh. Select the "Fill holes" function and select some of the
wholes. As soon as you press fill and then "accept" meshlab will crash with an
meshlab: fgtHole.h:472: void FgtHole<MESH>::getPatchFaces(int) : Assertion
Does anyone has similar problems or an idea what I'm doing wrong?
Thanks for your help!
Sorry but the mesh you have uploaded has not holes...have you downloaded the
last MeshLab's version?
In any case fill holes plugin is infamously known to be one of the most crash
prone. So I can easily believe you have this kind of problems!
Hi, thanks for your reply. I've downloaded meshlab 1.3.1 for Windows and I
also built it from source on a Linux box just to be sure that the problems are
not some Windows speciality. Regarding the mesh you find on the link above:
Yes, it seems to have no holes but when you click on the "Fill Holes" button
in the toolbar a dialog comes up which lists about 150 holes in the mesh.
Actually they are not really "visible" in the 3D view but somehow artifacts
probably caused by the way data is stored by obj. When I try to merge nearby
points the situation gets slightly better and the number of found holes
decreases a bit but for the remaining holes meshlab crashes anyway.
I have a lot of problems with this kind of holes as any program which tries to
interpret such an object as a solid refuses to work. I even tried to remesh
the object using the different algorithms available in meshlab but this seems
to crash meshlab as well. Do you have any idea what I could try to get rid of
Sorry, the meshlab version is 1.3.0a of course. So the latest version you can
This is really strange because every time I click on the Fill hole button
using this mesh a dialog appears saying "Mesh has not holes to edit". Which
version of Windows operating system are you using?
