I have a scan of one side of a car body-part. When I mesh the point cloud I get a 0-thickness texture instead of a watertight model. How can I make the mesh watertight as a e.g. 1 mm. thick shell?

Good morning, I have an issue I cannot solve while trying to create a mesh from a point cloud (obtained through LIDAR scan). I here attach the point cloud image: I have tried anything: screened poisson recostruction gave me terrible results (the geometry was completely off), I tried simplifing the point cloud but I couldn't achieve any result at all. I think one of the problem is with the normals, as I tried hundred of parameters but could not get Meshlab to compute it well. Using ball pivoting method,...

Hi everyone, I'm fairly new to Meshlab, and have been trying to utilize Meshlab to edit and heal meshes I've created in CloudCompare. But can't seem to get any of my meshes or pointclouds to open properly in Meshlab. A little background as to what I'm doing. I've taken lidar point cloud data collected from the DJI - L2 aerial lidar sensor, and have cleaned up the points as best I can. I then loaded said points into CloudCompare, and used CCompare's internal tools to generate a mesh based on those...

thank you in advance for your time. I'm sorry for the answer but I am a dentist with no experience with MeshLab. After overlapping two STL files of intraoral scans using the teeth as the reference points, I have selected the Region of Interest, to obtain a little rectangle. I would like to calculate the volumetric differences between the two overlapped scans in the ROI. Practically, in one STL we have the intraoral scan of the hemipalate, in the second STL we have the same scan following a surgical...

Hi Samu, Yes: back then I think I started using Per-Vertex Geometric Function, described here: https://stackoverflow.com/questions/71234206/scale-along-normals BUT I encountered some bugs (I reported them, they are maybe fixed now). So I ended up using Blender, where one can specify a length for the displacement of the normals.

I’m new to MeshLab (i.e. used it for the first time today) and am struggling to simplify my model. I created a model in Rhino3D and converted it to an STL but the file is too big for me to upload to the 3d printer so I downloaded MeshLab. When I try to simplify: quadratic edge collapse decimation (with texture), it says that the current mesh does not have “Per wedge texture coords”. Please could someone help me with what the means? TIA :)

Hello. I bought a nice STL of the Black Pearl from Pirates-Carribean. I wanted to change it to reflect Blackbeard's ship. (Queen Anne's revenge) Queen Anne's had more cannons. so, I duplicated some of the cannon ports. I started with the original file which is just one portion of the hull. . ( see file Original) Then I cut out a port and saved it as it's own stl. Then I made holes in the original where 2 new ports would be added. Finally I added the ports and flattened the layers. I ran the flattened...

Hello Community, I have a CAD part in WRL format with a file size of 5 MB, consisting of about 100,000 vertices and about 50,000 faces. It imports nicely into MeshLab and even retains the colorized surfaces of the original CAD model. It's a stamped part, mainly consisting of planar faces. In the CAD, these planar faces are (unnecessarily) broken up into thousands of triangles. Besides the flat surfaces, there are sharp edges and a few curved surfaces, see attached screenshot.

Hi, I use MeshLab to create meshes from point clouds. I import a 1 inch subsampled cloud into MeshLab, compute normals for the point set, and then run Surface Reconstruction with Ball Pivoting. From there, I apply a texture Parametrization: Trivial Per-Triangle and then Transfer: Vertex Color to Texture. The result is usually pretty good but I noticed the triangle edges have colors that don't blend well into each other (see attached PNG). What could be the reason for this, and is there any way to...

I have an application that can use the triangles in an STL file for its model. However, the model does not like long and thin triangles. Specifically if the height to base ratio is greater than 20, the triangle is rejected. Is there a way to modify a mesh such that this condition is fulfilled? Since long thin triangles seem to be used (for example) along the length of a cylinder, then one way might be to break a cylinder into several cylinders next to each other with the same axis.

I would like to use a photogrammetry software (e.g., 3DF Zephyr Lite) to get a measurable 3D model of a real-world object. In other words, the 3D model is required to be the same size as the real-world photographed object. However, any photogrammetry software I use produces a model with arbitrary coordinates. My idea is to photograph the real object together with a ruler and then "resize" the object via MeshLab on the basis of the real size of the ruler. However, I have no idea how to do this, and...

Hi. I was getting the same error in MeshLab using the 64 bits version for Windows. I tried opening MeshLab as Administrator and it worked. I guess for Ubuntu you could try running MeshLab as super user.

Hello, Recently I came across this program and for a couple of days I have been playing around with it now lets cut to the chase. My company is working in the marine industry and I have scans on ships that are on avarage 110(largest is 198) scans which I would love to be able to make solids using a program like this one. The scans are done with Faro Focus S150 on 1/4 resolution. I assemble them in Faro SCENE which can output in several formats that can be imported in MeshLab(wrl, xyz, ptx, pts)....

I've made a textured model in Metashape and exported it resulting in .ply and .jpg files. The .ply file loads into Meshlab without incident but I have been unsuccessful in importing the texture ,jpg file. In Meshlab the path I've been using(among many others) is Filters/Texture/Transfer: Vertex Colors to Texture. The message I get back is Failure loading textures: /xxx.jpg. I've changed the Texture width and height in the meshlab dropdown window to 4096 each but no success. In fact I've tried many...

Hi, we are trying to convert "coloured" PLY files like this: https://drive.google.com/file/d/14thcMfsb6wBmFnN0D6UShYhwFpQDTTCy/view?usp=sharing in OBJ format using meshlabserver. On Window system the command line meshlabserver -i fontana_mesh.ply -o fontana_mesh.obj -m vc works and we have a "coloured" OBJ file. On VMware virtual Ubuntu installation the conversion hangs. Some idea? Thank you. Gius

You can export them by using the "Flatten visible layers" menu option, when selecting any layer with the right mouse button.

Hi everybody, So far, I've had learned how to produce a 3D model pdf file with Meshlab and LaTeX. However, there is a limitation: it's not possible to create the u3d file with a structure of layers. Even if you load multiple layers in Meshlab, when producing the u3d file one has to choose one of these layers or flatten them all. On the other side, the manual of the LaTeX media9 package* shows an example of a 3D model with its respective model tree, when one can turn on or off each layer. So, which...

Hi, I have just downloaded the latest version of Meshlab 2020.07 in the hope it would resolve my previous issues with not being able to export a .ply or .obj file as a .U3D. At least with the 2020.06 version I was able to get a TeX file on to the desktop. Now I simply get two error messages as below. Please can anyone help? Thanks, Jim [A screenshot of a social media post Description automatically generated][A close up of a sign Description automatically generated] DISCLAIMER: This email is intended...

H, I have an .obj 3D model with textures I have exported from Regard3D. This opens fine in Meshlab. However I have noticed in the bottom bar of meshlab it only has FC and WT attributes. I have tried unsuccessfully to decimate the mesh with textures and am wondering if it is because it doesn't have VT & VC? I have read that WT is not used much now? How can I transfer the attributes to the vertices? Thanks, Widepan

I am using Meshlab in my research. Does anybody know where can I find the literature about the algorithms of Quadric Edge Collapse Decimation and Clustering Decimation? (I do NOT use QECD with texture)

I have a 3d structure that I want to 3d print but it is divided into multiple pieces (stl files). When I import them all together using meshlab they are assembled but I want to have them aligned and separate in the same plane so that I can 3d print them all at the same time. Any idea how I can do that ? Thanks in advance for your help

Hi! When i try to import cameras from Zephyr aerial to Meshlab useing Boundle format i got all correct but all the cameras turned AWAY from target (not TO target). Please see the screenshots: from Zephyr: https://ibb.co/sgs5kC0 from Meshlab: https://ibb.co/31Q25sw Can you help me? Tnx. P.S. On 3dflow forum 3Dflow Staff told me that: "I'm afraid that's an import issue from Meshlab, as bundler export seems to be working correcly on Zephyr's end."

I used the MeshLab remesh filter 'ISO parameterization remesh' for remeshing 3d obj files into the meshes with different edge lengths. I am not sure how to config the options in 'ISO parameterization main'. Something like Am min size and Am max size, and Optimization Criteria. what the contribution of these options to the results. As I notice for some result meshes, there is one area of triangulation that is heavily distorted. For the remesh process, how can I approximately know the relation between...
