![]() ![]() The menus are expansive, and contain almost everything you could want for cleaning up meshes and re-texturing. It still looks and does almost exactly the same as it has for the past decade, which is to say it does a lot. I was going to start this section by lamenting that it hasn’t been updated in years, but having just visited the site I see that a new version was released literally just a few weeks ago, version 2020.02. Meshlab was a staple of mine even during my PhD 10+ years ago. We do lose the texture when changing the topology, though MeshMixer can keep colours at verticies.Īutodesk Meshmixer has become my go-to software for general mesh maintenance. Same view of the raw mesh and the reduced and retopo’d mesh. It loads data very quickly, and has a pretty wide range of tools for editing meshes, including sculpting brushes, tools for reducing and retopologizing meshes, and analysis tools for fixing holes/intersecting polygons and so forth. It’s really designed for preparing models for 3D printing, but it’s tools for generally cleaning up meshes are fast and easy to use. Meshmixer is a phenomenal piece of free software. Depending on your work flow, that may mean regenerating the UV maps (which tell software where to put which parts of the texture on your model) and for high-resolution meshes this is not a trivial task.Īs I list the software, I’ll include the above tags to let you know what it can do. But once you start editing your model, you may wish to re-texture it. Photogrammetry will generally produce a model and a texture file. Re-texture/generate UV maps – I hate working with textures.For most of my purposes, this isn’t entirely necessary, but for animation/modelling and the like, I gather it’s good practice ![]() Retopologize the mesh – this is something I’ve only recently got into, but essentially retopologizing the mesh makes the polygons more evenly distributed.I’ll often keep the high-res mesh for measurements, and a lower res mesh for visualization. Reduce the mesh – reducing the number of polygons makes it easier to hand the mesh for rendering etc.Merge meshes – If I’ve had to scan an object in two attempts (top and bottom), I’ll need to align those meshes ideally algorithmically, but by hand if I have to.Clean it up – remove spurious parts of the mesh.If I produce a high resolution mesh with photogrammetry, say, then here’s what I’ll generally want to do to that data: As usual, my focus is on freely available software. I want to detail here some of the software I’ve come across that can be used to clean up, reduce, and generally process 3D data – particularly meshes but also point clouds. For the most part that data is usually very high resolution, and often quite noisy and in need of cleaning up. Working with photogrammetry, laser scanning, and all the other techniques I dabble with/intimately rely on, I generate a lot of 3D data. ![]()
