The instructions from provide a good base for the following steps, as well as the MakerBot tutorial. MeshLab provides several ways of converting a point cloud to a mesh. c) In the Align Tool window, choose a mesh that you want to use as base position, and click Glue Mesh Here. Therefore, we need to convert it to a mesh with surfaces that can be easily rendered. Otherwise Meshlab has a fairly efficient implementation of vertex attribute transfer (transferring the color information from one model to another). The point cloud format is tricky to show for example using the HoloLens. When using the poisson recon you can just check 'keep color' or something like that. Using vertex colors on adecimated model usually does not look very good, since the surface of each triangle is just the color interpolation of the three corner vertices. Just make sure, that the decimated mesh is in the same position as the camera poses.Įdit: Of course you could just use the decimation algorithm implemented in photoscan. This time, press File Import Mesh, and choose the. III: Press File Export Mesh As in the menu bar and save the model as a. After decimation just reimport the mesh to photoscan and rebuild the texture. II: Press File Import Mesh in the menu bar and select your. Alternatively you could, as been suggested, just remesh the points of the mesh using CC poisson implementation (you don't have to randomly subsample points from mesh, just use a lower octree depth).

The required workflow depends a bit on whether you are talking about vertex-colors or proper texture maps.įor texture mapping, you could decimate your mesh using either Meshlabs 'Quadric Edge Collapse Decimation', which usually creates quite good results.
