![]() ![]() I would liek to know how to work with Open3D to get such kind of surface reconstruction.įrom Open3D I am getting meshing something like this which is shown in the link below which contains lot of gaps. This short and sharp demo shows you how to use Meshmixer to fix holes and gaps in your models so they can be used for 3D printing. 1 Answer Sorted by: 2 It seems to me that your boundary is turned towards the exterior of the cylinder, so closing the hole building a patch of triangles would produce several undesired auto-collisions. I have attached the “.xyz” file along with this mail and also the mesh obtained from Meshlab. How to repair holes and gaps in surfaces How to delete or trim unwanted surfaces, particularly useful for 3D. I need water tight mesh since I want to work on further process called simulation based on this mesh. The hole filling algorihtm is a variant of the one presented in: Liepa, P., Filling Holes in Meshes, Proceedings of the 2003 Eurographics/ ACM SIGGRAPH Symposium on Geometry processing, Eurographics Association, 2003, pp. To reduce the overall number of triangles in your model, open the model in MeshLab and from the Filters menu select Remeshing, Simplification, and Reconstruction and then Simplification: Quadric Edge Collapse Decimation. Also, I am confused with the terminologies of multiple radius while working with Ball Pivot Algorithm. But, I am unable to do watertight mesh using Open3D. this kind of hole filling with curvature continuity from the video is not an trivial thing to do and i don´t think there exist any out of the box solution in houdini you could use. ![]() I am very excited to work with this library.īased on this, I tried to do surface reconstruction using Ball pivot algorithm and also Poisson surface reconstruction. if you should fill all the created holes and interpolate in some way the original mesh, This can be done inside meshlab, that provides some hole-filling. I was researching and found Open3D library. Why even using sculpt mode to fill holes in a mesh object Its not meant for that. I want it to be converted to 3D mesh using python. I have a set of 3D datapoints which looks similar to sphere. ![]()
