Off by default because it is very useful only in particular situations like when you have perfectly flat areas finely tessellated. 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. Try 500,000, or even lower if the model quality doesnt deteriorate too much. It’s on by default.Īdd additional simplification constraints that try to preserve the current shape of the triangles. Go to Filters Remeshing, Simplification and Reconstruction Simplification: Quadric Edge Collapse Decimation (with texture) (if youre using a texture). 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. Optimal position of simplified vertices: Yes. 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). 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. Quality threshold affects the simplification penalizing bad shaped faces. 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.
