![]() try to reduce the most redundant data to get the lightest file size. What's the problem in blender? Vertex colors or texture maps? Both work flawlessly. To obtain a proper STL file, you need a program that triangulates the points to. Otherwise Meshlab has a fairly efficient implementation of vertex attribute transfer (transferring the color information from one model to another). Once the command is computed, a new pop-up window will appear. A pop-up window will appear in the top-left corner of the viewport. free software: Windows 3D BuilderDownload. When using the poisson recon you can just check "keep color" or something like that. To make an STL file smaller, follow these steps: Press CTRL + A (Command+A for Mac) to select the entire model. Reducing the number of triangles will reduce the smoothness of the surfaces, but also the file size All you need. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. ![]() 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. After decimation just reimport the mesh to photoscan and rebuild the texture. 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). Use the slider labelled Reduction level to decrease the amount of faces. ![]() ![]() 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. Import your model into the software and go to Edit > Simplify in the menu.
