ULTIMATE UNWRAP 3D VERTEX WIEGHTS SOFTWARE

I hope these steps help people to come up with their own textured mesh. Initially I couldn't find any proper step-by-step process to create textured mesh on meshlab.

These are the three files needed to view textured mesh on any '.obj' file viewing software like Blender or autodesk etc. If originally you saved your mesh as mesh_1.obj, after the above operation it will create mesh_1.obj.mtl and mesh_1.png. There is also a texture image file saved in the same directory where original mesh was saved. Texture height (px) : 4096 (make sure this is same as Texture Dimension in the above steps).Texture width (px) : 4096 (make sure this is same as Texture Dimension in the above steps).Texture file : (If your mesh was saved as mesh_1.obj, the texture file name should be mesh_1.png).Now go to Filters -> Texture -> Transfer: Vertex Color to Texture. Make sure under Wedge, TexCoord is checked. After clicking on save, it will open saving options. Method : Basic (with Space-optimizing somethimes Meshlab crashes.).Go to Filters -> Texture -> Parametrization: trivial Per-triangle. Go to Filters -> Texture -> Convert PerVertex UV into PerWedge UV. Go to Filters -> Texture -> Per Vertex Texture Function. Make sure to select Poisson in the Show layer Dialog to peform further operations. Now that we have a mesh, next step is to get the texture for the mesh from the pointcloud. Texturizing the Mesh using pointcloud color attributes. Then click on delete face button (triangle and threwe vertex with a cross over it). To remove them go to Filters -> Selection -> Select non Manifold Vertices.

Even after the above operation some noise faces are seen.

Use the default value and make sure Remove unreferenced vertices is checked. To remove them go to Filters -> Cleaning and Repairing -> Remove isolated pieces (wrt Face Num.).

After this operation, still some noise faces can be seen.

Then click on delete face button (triangle face and three vertex with a cross over it). By default the value is automatically computed, just click on apply. To remove them go to Filters -> Selection -> Select Faces with edges longer than.

One can observe that it has also created some extra surfaces.

Make sure to select that to peform further operations.

This will create another mesh layer called Poisson in the Show layer Dialog which has surfaces now.

Initially try with default parameters then later one can play around with reconstruction depth, number of samples and interpolation weight values.

So go to Filters ->Remeshing, Simplification and Reconstruction -> Screened Poisson Surface Reconstruction.

Next we are going to use Poisson Surface reconstruction to do meshing.

Make sure if your normals are properly computed by going to Render -> Show Normal.

For Smooth Iteration initially try with 0 value and may be later it can be tried with values between 5 - 10. Initially try with 10 and try to get a mesh and later see if this can be improved by increasing the neighbour number.

So go to Filters -> Point Set -> Compute normals for point sets.

Now we need to compute normals for point set. If not visible, it can be opened by navigating to View -> Show Layer Dialog.

After point cloud simplification, make sure to select Simplified point cloud in the Show Layer Dialog on the right hand side.

Make sure Best Sample Heuristic is checked. Enter Number of samples circa 5% of original number of points.

So go to Filters -> Point Set -> Point Cloud Simplification.

Next we need to reduce the number of point samples for smooth meshing.

Point Cloud Simplification and Normals Computation

Before importing make sure you do some pre-processing / cleaning on point cloud so as to ease the process of meshing.

Import the pointcloud file in '.ply' file format in Meshlab.Steps to create Textured Mesh from Point Cloud using Meshlab Get your PointCloud into MeshLab
