There's a lot, but I'm sure you get the idea. This could be a selection of certain faces and vertices, applying a colour to the mesh, smoothing, remeshing, resampling. A filter in MeshLab is any operation performed on the mesh. Below that we have some display and shading options, and at the bottom is an output window. Our current and only layer, the sphere, is highlighted in yellow. After that, you should have a sphere plonked right in the middle of your workspace!Īs you can see, this has also opened up a panel on the right hand side of our screen. This ensures that we have enough triangles in our sphere mesh to work with in the later stages. When prompted, keep the radius setting at 1 and set the subdivision level to 6. This can be generated right within the software under Filters > Create New Mesh Layer > Sphere. In order to make a voronoi sphere, we're going to need a plain old regular sphere mesh to start with. Once you've done that and opened it up, you'll be met with this user interface: The process The first step is going to be to head over to the MeshLab website and download and install it on your computer. For this tutorial, we'll be using only a few, but hopefully it will give you an idea of the huge range of applications that this software can have. Perhaps there were developers available during lockdown that got involved in the project? The latest release doesn’t add new features, but instead replaces a major under-the-covers 3D engine.Īs I mentioned, Meshlab is entirely free to download, and is available on Windows, Mac and Linux platforms.MeshLab is an extremely powerful mesh manipulation tool with a lot of advanced capabilities. Previously we had seen no updates between 20. Lately Meshlab has been providing more frequently software releases, with the latest being only a few months old. You can usually figure out how to do almost anything quite quickly. This is ironic, because Meshlab itself offers simplification tools for 3D models.įortunately, it turns out there are plenty of tutorials online for using Meshlab in a variety of commonly encountered situations. This happens because contributors to the project “contribute” and few are interested in “simplifying”. Meshlab, like many open source tools, suffers from feature overload. A new Meshlab user typically freaks out when facing the voluminous menus and lack of obvious workflow. If there’s one downfall for Meshlab, it would be complexity. While Meshlab is an open source product, it is certainly powerful enough to be used anywhere, even in big commercial operations, where the usual software may still be deficient in function. I find myself turning to Meshlab frequently, as other products often don’t have the function required, and Meshlab usually does. You’ll also be able to trim, fill holes and simplify the scan into a truly 3D printable model. Meshlab is particularly useful when combined with 3D scanning, as it can accept the point clouds typically generated by scanners and convert them into proper meshed 3D models. However, it can do far more than basic operations. Meshlab can perform many activities occasionally found in other 3D design tools and utilities, such as filling holes, or cutting models.
