This seems to happen automatically in MeshLab when importing models. Ensure you are always viewing the model with flat shading, easy to be mislead by smooth shading with normals. Off by default because it is very useful only in particular situations like when you have perfectly flat areas finely tessellated. The following describes one possible option for smoothing meshes in MeshLab, the example used here is shown below. Like the quality threshold it affects the accuracy/complexity ratio.

It can greatly improve the quality of the shape of the final triangles on perfectly planar portions of the mesh. How to reduce the number of polygons of your 3D file with Meshlab Target number of faces: Here type the number of polygons you wish your file to have. It’s on by default.Īdd additional simplification constraints that try to preserve the current shape of the triangles. If disabled, the edges are collapsed onto one of the two vertices and the vertices of the final mesh are a subset of the original mesh. When collapsing an edge the chosen vertex position minimizes the current estimated error. our example case thatll significantly reduce material use and printing time. Optimal position of simplified vertices: Yes. PLY (Polygon) is a more extensive format developed at Stanford to aid the. The value is in the range : 0 accept any kind of face (no penalties), 0.5 penalize faces with quality Normals, Curvature and Orientation > Re-Orient all faces coherently (note that this will only work for manifold objects). This is useful to remove points inside the. You can also use to select points on a plane. To approximate accurately the original shape only with well shaped triangles you require a higher number of faces with respect to allowing more freedom in the final triangle shape. How to clean up point cloud in Meshlab Use to select unwanted area. Keeping the faces quad-shaped would be an amazing bonus. I was wondering if there are any polygon reduction tools available that would reduce them, but keep the UV seems. Quality threshold affects the simplification penalizing bad shaped faces. So I've got a bunch of models that are really nice, but are a bit on the high-poly side. Keep this below 1 million.Įnter a value between 0 and 1 here the higher the value the harder MeshLab tries to stick to your original model's shape. Target number of faces - Self explanatory.
If your model is textured, there is also an option (with texture) that will do a good job at keeping your textures positioned properly.

$ gmsh & MeshLab, open source and free for Windows, Mac and Linuxįrom the menu, select Filters > Remeshing, simplification and construction > Quadratic Edge Collapse Detection. There's a limit to the complexity of objects that you can upload to Shapeways: they can have no more than 1 million polygons.

If you just want to view what is in the file you can try gmsh. Polygon reduction with MeshLab Install sudo apt install meshlab or Download MeshLab From the menu, select Filters > Remeshing, simplification and construction > Quadratic Edge Collapse Detection. Sometimes a STL file has too much detail for Tinkercad. Try simplifying the mesh before re-importing it. Tinkercad meshes are limited to 300,000 triangles.
