Cast Modifier
This modifier shifts the shape of a mesh, curve, surface or lattice to any of a few pre-defined shapes (sphere, cylinder, cuboid).
Decimate Modifier
The Decimate Modifier allows you to reduce the vertex/face count of a mesh with minimal shape changes.
Duplication is not a modifier
There are currently four ways in Blender to procedurally duplicate objects. These options are located in the Object menu.
Notes :
Vertices
- This creates an instance of all children of this object on each vertex (for mesh objects only).
- Faces
- This creates an instance of all children of this object on each face (for mesh objects only).
- Group
- This creates an instance of the group with the transformation of the object. Group duplicators can be animated using actions, or can get a Proxy.
- Frames
- For animated objects, this creates an instance on every frame. As you will see on this topic’s subpage, this is also a very powerful technique for arranging objects and for modeling them.
