Step 2: Follow these steps in the menu: Filters -> Remeshing, Simplification and Reconstruction -> Simplification: Quadric Edge Collapse Decimation (with texture)īy the way, if you convert the 3D model into GLB (glTF), the file size will be even more compressed. it’s still acceptable for me, and it depends on number of reduced points.Īn open-source 3D mesh processing tool called MeshLab can help! Available for Windows, macOS, and Linux. Reducing the number of polygons in a model is useful to improve storage, transmission. The Quadratic Edge Collapse Decimation tool allows you to set a target poly count. 3.1 Triangle reduction Step 1 Menu File -> Import Mesh Step 2 Tick the Wireframe Icon on top Step 3: Select the (maybe) best triangle reduction filter Menu Filters -> Remeshing, simplification, and Reconstruction Quadric Edge Collapse Decimation. Figure 7-5: Decimating sculpts in MeshLab. This is useful to remove points inside the. You can also use to select points on a plane. Reduced: UV coords are also reduced as a side effect, then the stripes pattern on the shirt was slightly deteriorated. Meshlab includes several interesting algorithm for repairing and simplifying meshes. How to clean up point cloud in Meshlab Use to select unwanted area. Reduced: Each point can be recognized in the reduced model. Original: Almost completely filled in orange and points can’t be recognized. I reduced mine by about 93, resulting in the low-poly model shown above. Since the topology of 3D scanned model is usually complex, reducing the number polygons seems difficult… But actually quite simple to do! Here is the result of the reduction. Use the Reduce Mesh tool in Rhino to reduce the number of faces of the mesh. Some tools like ZBrush can quickly create a high polycount, so its easy to run into this limit. More polygons than that quickly become too much work for our servers and printers to handle. 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. MeshLab offers different ways to simplify (decimate) triangulated surfaces, able to preserve geometrical detail and texture mapping, or to selectively reduce. ![]() ![]() Therefore the file size is proportional to the number of polygons and are at least 10MB which is unsuitable for web usage. Polygon Reduction with Meshlab There's a limit to the complexity of objects that you can upload to Shapeways: they can have no more than 1 million polygons. 3D models especially 3D scanned objects tend to have a high polygon count.
