    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 :)

    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.

    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...

    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."

    Thanks @Tim Ayres for the great explanation. Could you explain the way to use the same script for .obj files

    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...

    I have two different files imported into meshlab. The first one is an implant and the other onde is the femur. I want to export these two components as one. How can I do this?

    The problem is that the mesh it's saving is not the right layer. When the new layer is made from the resample, the scripting interface fails to capture a) changing layers and b) deleting the layer with the original object. Since the new object is contained within the old object, it's totally invisible in the new mesh.

    Is it displayed anywhere just how much rotation (in degrees per axis) and translation (in mm per axis) that an stl mesh undergoes when I align it with a Base mesh? Appreciate any help. Thanks

  • shan solo shan solo posted a comment on discussion Help

    In my revel in the file stored by means of meshlabsever is the final (backside) layer. For instance, if the original mesh is resampled, the resampled mesh may be saved ("Offset mesh" layer). This is with 1.34BETA on 64 bit Windows here. Are you seeing one of a kind behavior? FYI, I am also using meshlab to script hollowing meshes for 3-D printing.

    Did you ever get this to work? If so, how?

    Dear fellows, given three 3D meshes : 1)large 3D face mesh , 2) small 3D face mesh (chidren) and 3) 3D mask mesh, I would like to deform each time the 3D mask mesh according the target 3D mesh. You can find an example (a GIF) attached (you can download it for better visulalization) Any help please ?
