问题 I want to write a script in Python which can generate facegroups in a STL as per the Face Normal value condition. For example, Provided is the snap of Stl, Different colour signifies the face group containing the triangular faces satisfying my given face normal threshold. Is there any simple way to do this in python? Face Group STL 回答1: I'm sure there's a python library to load stl files, but I've always just written my own, since the file format is pretty simple (see the Wikipedia article

问题 How to remove self-intersection of a mesh with the Meshlab application or vcglib? 回答1: This is out of the scope but there are some functions in CGAL. This is still experimental and not documented but you can use the function remove_self_intersection(). Depending on the type of self-intersections, you can also use the (also experimental) function autorefine_and_remove_self_intersections(). The first function is more likely to be used when you want to remove self-intersection due to loss of

问题 I need to prepare 3D mesh of car seat to further dynamic analysis. Because the mesh has high resolution it is necessity to make a simplification using one of the available options in MeshLab. What module I have to use to get the mesh with lower resolution in places where the faces are simple (regular, simple surfaces) but higher resolution where details must be preserved (curvatures, folds, bends). The screen of the object I attach to this message. enter image description here Thank you for

问题 I have a folder with hundreds of STL meshes and I want to merge them in meshlab using the flatten command. I´m using the regular GUI and when I go to file open and pick all these STL files, I´m prompted for each and every file if I want to "Unify Duplicated Vertices". As I have hundreds of them, this is unacceptable. Is there any way to configure the software to apply my "yes" to all models it opens? Tks! 回答1: I got an answer to my question which duplicates yours: user suprjami said You can't

问题 I am new to 3D, I have a point cloud for this I want to form a mesh using python libraries. But I am able to do with using meshlab functions those are "Filters --> Pointset -- > compute normals for pointsets" and "Filters --> Remeshing,Simplifications and Reconstruction --> Surface Reconstruction ::Poission" Is there any methods to doing above meshlab functions with using python to make it automate. Thanks 回答1: You can make a system call to meshlabserver, which comes with Meshlab (it's in the

问题 I have a scene consisting of several colorized voxels. When opening it in meshlab all points are plotted as 2 dimensional squares. Is it possible to render a scene where the squares are replaced by 3D cubes with additional lightning / reflectivity in meshlab? This is what I'm getting so far: I rather want something like this: 回答1: I wrote a voxel plot script for blender. https://github.com/cagcoach/BlenderPlot/ BlenderPlot takes .mat files as input and generates a scene containing the voxel

问题 I have a high resolution triangular mesh with about 2 million triangles. I want to reduce the number of triangles and vertices to about ~10000 each, while preserving its general shape as much as possible. I know this can be done in Matlab using reducepatch. Another alternative is qslim package. Also there is decimation functionality in VTK which has python interface, so technically it is possible in python as well. Meshlab is probably available in python as well (?). How can I do this kind of

问题 I need to reconstruct a surface mesh of a terrain from a dense point cloud. Is it possible to generate polygonal meshes from point clouds in Meshlab v2016.12? 回答1: Yes you can!. The process of generating a mesh from a point cloud is called surface reconstruction. There are several surface reconstruction methods avaliable in meshlab. Go to Filters -> Remeshing, simplification and Reconstruction There you can select one of the many choices avaliable. To guide you a little: Delanuay

问题 I've followed this tutorial to export a POV-Ray graphic to a STL file, through Meshlab. I've also tried the export to the OBJ format. Everything seems to work fine from the creation of the POV-Ray graphic to the exporting in Meshlab. But then I've tried to render the graphic in R with the functions readSTL and readOBJ of the rgl package, and the problem is here. In fact, the exported STL file is empty: solid STL generated by MeshLab endsolid vcg So, of course, rgl::readSTL renders nothing in

问题 every time I open an STL file with Meshlab, a window pops up and asks, whether I want to "Unify Duplicated Vertices". It is sort of annoying that I always have to press the "OK" button. How can I tell Meshlab that it should always unify them without asking? Thanks! 回答1: You can't. I provided feedback to the developers via Facebook that they should make this an option. 回答2: It is in the upcoming MeshLab version You can try (at your own risk :) ) the prerelease builds; you can found them here:
