QUESTION

Meshlab Laplacian Smooth introduces spikes

Asked 2021-Apr-06 at 17:31

I am using MeshLab to smooth a mesh obtained from a 3d numpy array through marching_cubes and pymesh. I am processing a few similar meshes and only one of them is giving me this problem. The filter used is Laplacian Smooth with parameters:

smoothing steps = 1
1D boundary smoothing = True
cotangent weighting = True

Attached are the images of the mesh before and after the Laplacian smoothing. Unfortunately the images have to be cropped in the interested areas due to privacy concerns.
Any help in tracking down the issue or any debugging suggestions would be really helpful.
Thank you!

Can you provide a mesh sample? it could be a numerical issue due to degenerate zero area triangles that can happen as a result of MarchingCubes. The reason is that Laplacian smoothing tries to move vertices along the tangent planes of the surface that results undefined for zero area triangles. Eventually you could also try to remove those degenerate triangles by running a merge close vertices filter. This issues can came up also because desktop meshlab runs on float while its python counterpart pymeshlab runs on double. Eventually just try the mesh from numpy arrays directly using pymeshlab

Sklearn and Pymesh import causes conflicts

Asked 2021-Feb-03 at 11:53

I am working on processing 3D meshes using PyMesh. pip install pymesh2 has build error. Hence I installed from another release from the official github page. I am using pymesh2-0.3-cp36-cp36m-linux_x86_64.whl. I installed scikit-learn using pip install. Both installed successfully in my system. While importing them, I observed something strange.

QUESTION

Python Implementation for creating a triangular mesh from an array of closed loop planar contours

Asked 2020-Dec-13 at 11:52

I'm a wee bit stuck.

I have a 3D point cloud (an array of (n,3) vertices), in which I am trying to generate a 3D triangular mesh from. So far I have had no luck.

The format my data comes in:

(x,y) values in regularly spaced (z) intervals. Think of the data as closed loop planar contours stored slice by slice in the z direction.
The vertices in my data must be absolute positions for the mesh triangles (i.e. I don't want them to be smoothed out such that the volume begins to change shape, but linear interpolation between the layers is fine).

Actually there are two ways of having meshlab functionality in python:

The first is MeshLabXML (https://github.com/3DLIRIOUS/MeshLabXML ) a third party, is a Python scripting interface to meshlab scripting interface
the second is PyMeshLab (https://github.com/cnr-isti-vclab/PyMeshLab ) an ongoing effort done by the MeshLab authors, (currently in alpha stage) to have a direct Python bindings to all the meshlab filters
