4 Procedural new Decimate methods in geometry nodes - Blender project

In some contexts the native Decimate Modifier of Blender could not be enough, mostly when you want to preserve zones of high density or high mesh curvature. With this file you can access to 4 new decimate methods made in geometry nodes using Blender v. 4.0.2.

In the content you will find 2 files

• the first that uses the common Switch node to determine what method you can choose
• the second that uses the new Menù Switch node of Blender from v. 4.1, very powerful to set the method you need in your stack modifier.

Both files will contain the examples used in the tutorial.

If you encounter issue and missing of some connections of the geometry nodes setup please write me with youtube comment or my Discord server (link in the description of all my video tutorials).

Features:

• Method: 1 - By Angle, 2 - By Area, 3 - By Distance, 4 - By simplified mesh, angle & distance
• Max. angle: set the maximum angle between faces in which you want to apply the method n. 1 or n. 4.
  The higher this value will be, the bigger mesh zone will be affected by the decimate modifier
• Min. area: set the minimum area from which you want to apply the method n. 2.
  The lower this value will be, the bigger mesh zone will be affected by the decimate modifier
• Min. distance: set the minimum from which you want to apply the method n. 3 or n. 4.
  The lower this value will be, the bigger mesh zone will be affected by the decimate modifier
• Strength: set the distance of the Merge by distance node used in the decimate modifier to merge the vertices of the mesh when applying the decimate operation.
  The higher this value, the fewer faces there will be in the final mesh.
  Advantage: fewer total faces, disadvantage: more sharp result on the decimated surface
