NodeSlicer Path Operations Visual Test Suite

This directory contains visual verifications and plots for all operations in the Path Operations node:

• Maximum Coverage (Union): Boolean union of all polygons layer-by-layer.
• Minimum Coverage: Per-layer intersection of all objects having paths on that layer (ignoring empty layers so single-object layers are preserved intact).
• Intersection: Standard boolean intersection across all inputs.
• Subtract: Difference subtracting subsequent inputs from first input.
• Exclusive Or (XOR): Symmetric difference across inputs.
• Zip Paths: Layer-by-layer toolpath stream interleaving.
• Extend Paths: Sequential toolpath concatenation.
