This Geometry Nodes setup replicates the functionality of Blender's built-in Mirror modifier. It supports mirroring across the X, Y, and Z axes and allows users to specify a target mirror object or manually override the location and rotation. The setup includes support for merging compatible geometry. It also introduces custom clipping behaviors, requiring users to select either positive or negative clipping which operates within the original object's space. An experimental recenter option attempts to center the mirrored results around the original object's origin based on the mirror center.
