Otherwise Meshlab has a fairly efficient implementation of vertex attribute transfer (transferring the color information from one model to another). When using the poisson recon you can just check "keep color" or something like that. Do Quadratic Edge Collapse Decimation several times till you are happy we the reduced mesh. Pick: Remeshing, simplification and reconstruction / Quadratic Edge Collapse Decimation. If your model is textured, there is also an option (with texture) that will do a good job at keeping your textures positioned properly. Import DXF mesh back into SU Note: In Meshlab: Turn of flatline display, goto Filters menu. From the menu, select Filters > Remeshing, simplification and construction > Quadratic Edge Collapse Detection.
#Meshlab quadric edge collapse decimation install#
Luego, pincha en Filters > Remeshing, simplification and reconstruction> Quadratic Edge Collapse Decimation, como se muestra en la imagen de abajo. To start, please download and install MeshLab and import your model. Una vez que abras tu archivo, vers el nmero de polgonos que contiene en la parte inferior de tu pantalla. 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. Primero, debes descargar e instalar Meshlab e importar tu archivo. Simplification: Clustering Decimation Filter Remeshing,Simplification, Reconstruction Simplification: Quadric Edge Collapse. 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. For example, drag and drop the OBJ file from your 3D scan into the window or go to File Import Mesh. After decimation just reimport the mesh to photoscan and rebuild the texture. Reduce the vertex count of the mesh for reduced. 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). Filters Remeshing, Simplification and Reconstruction Simplification: Quadric Edge Collapse Decimation. It uses data parallelism as provided by OpenCL and has. 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. Load scanned part in MeshLab, then apply Filters > Remeshing, simplification and reconstruction > Quadric Edge Collapse Decimation. The algorithm performs edge collapses on manifold triangular meshes driven by a quadric error metric.
