Here’s a series of images starting with the raw mesh, the progressively reducing using the ‘Quadric edge collapse (with texture) function. Just one of the many sub-menus, this one is just for dealing with normals and curvature. 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.
