Meshlab remeshing5/30/2023 When I see so organic shape as yours I have so many questions in my head. You can import that quad cage as subd cage into MoI3d and it will also convert it to patches. Sometimes I do quad remesh (there is free instant meshes but I prefer Zbrush Zremesher). I think CAD is not friendly enough for meshes to play with it so I try prepare meshes earlier in more friendly environment. Sometimes it is so bad that only manual method is possible. Sometimes I use remesher to leave all bad topology behind. Sometimes I cleanup mesh errors before I bring it to other software (self intersections, ngons, non-manifold edges and polygons). Sometimes I sculpt scans in Zbrush before doing auto retopo (remesh) to have better surface for remeshers. If surface after import is not good enough then you may build new one over that surface in MoI (second retopo in nubrs this time). Sometimes I do retopo by hand over scan in polygons to have subd cage and I import it to MoI3d (native subd importer or scrip[t). May I ask why you need that surface in NURBS? That`s why I have not made it in polygons. This model was prepared for CNC machine and they demanded STEP file. This was no super exact but good enough to make that specific hard surface model. ![]() Next I`ve created curves with using "on surface" snapping to create solid model after. I had one work few years ago where I decimated scan mesh in Zbrush and imported to MoI3d with Max Smirnov OBJ importer. I would do this in Modo or Zbrush but it`s also easy on Blender or MeshMixer. If you want thicken and trim it only it`s super easy in most polygons apps. I think that not always is worth to move scans from polygon to nurbs. Maybe it doesn`t help you directly but I hope it will be helpful. ![]() ![]() I create new designs basing on 3d scans often. There does not seem to be much information about this, presumably the exterior edges of the mesh would just need to be extruded a bit and filled to give some thickness, sealing the mesh? Does that need to be done manually or is it something Meshlab is capable of doing(lack of documentation makes it hard to discover this information).Thanks for bringing that topic. With such a surface it seems to cause heavy distortion and ballooning as it tries to seal the mesh. For the ones that do, they could be linked to the youtub video from the website.Īnother feature "Automatic Remeshing" seems to be Iso Parametrization? Requiring water tight meshes, when a mesh is not water tight(eg a slice of a larger model, like the face of a cube) Is Surface Reconstruction: Screened Poisson the only way to go about it? ![]() The slides show off great features of MeshLab but I feel teased as it is not clear how to achieve them(unless a video exists by Mister P). I would love to know how to perform this. Usually I will come across mesh reduction features, whereas the way the image is shown it looks like rather than focus on decreasing the mesh it improved the quality/topology conforming to the shape better but not degrading the overall shape/form/silhouette. I have tried to identify this feature but it's keywords are not easy to perform queries with. From the website slides, the image before/after looks very interesting.
