meshlab

问题 The latest version of Meshlab claims it has the functionality to hollow out models for 3d printing. I've looked through all the menus trying to find this feature without any luck. Anyone have any idea where this functionality is? 回答1: To hollow out a closed model using meshlab you have to: use the " Uniform mesh resampling " filter to build a second offset mesh; use a negative offset distance in world unit to build a second, internal, surface, invert the offset mesh orientation using the "

问题 Comparing Models , this is a feature of meshlab. there is a shot introdution in the web home of meshlab(http://www.meshlab.net/). but how ? there is none exmple. somebody can help me? give a exmple or a document, thanks a lot. 回答1: As it has been mentioned in that short introduction, MeshLab compares two 3D models by calculating the Hausdorff distance between them. This option is available under Filters menu ( Filters -> Sampling -> Hausdorff Distance ). Before applying this filter, you need

问题 I have a bunch of .ply models of human faces. I want to open them one at a time in MeshLab, but each time in the same orientation. How do I reorient the planes in MeshLab so they better align with the faces? In other words, I want to view each face in a standardized orientation, such as the Frankfort Horizontal Plane parallel to the ground, so that when I go to filters --> normals, curvatures, and orientation, --> transform: rotate and I rotate the faces about a fixed axis and center of

问题 after running the Screened Poisson Reconstruction in Meshlab, I got the mesh with some extended surface as in this figure Does meshlab support any tools for removing that? 回答1: MeshLab is using an implementation of PoissonRecon, which is found here: https://github.com/mkazhdan/PoissonRecon What you are seeing is due to the default boundary condition used by the algorithm, which is a Neumann boundary condition. Unfortunately, MeshLab does not allow you to modify which boundary condition is

问题 When I import and XYZRGB (that I generate programatically), MeshLab renders the point-cloud, but the colors are missing. How can I assign textures/colors to vertices. I have tried "Vertex Attribute Transfer" but nothing happens. 回答1: Rename the extension .xyz to .txt. Then choose the x y z r g b option when importing the file. in meshlab source: http://www.laserscanningforum.com/forum/viewtopic.php?f=168&t=8052 来源： https://stackoverflow.com/questions/22850905/meshlab-how-to-import-xyzrgb-file
