nx_adaptive_layer.nx

nx_adaptive_layer.nx -- bits-up Q14 multi-criteria adaptive layer height computation for FDM (and any direct-write process where the substrate computes per-Z layer thickness from local geometry). ===================================================================== EXCEED axis (research baseline) ===================================================================== Industry adaptive-layer-height treatments (as of 2026-05): Cura 5.x `adaptive_layer_height`: CURVATURE ONLY. Computes mesh surface curvature per candidate Z and outputs layer height = max if flat / min if curved. Single-input heuristic from Wong & Pfaffenberger 2017. OrcaSlicer 2.3.2 "By Slope": CURVATURE ONLY. Same algorithm family as Cura. PrusaSlicer 2.7 "variable layer height": CURVATURE ONLY. Manual or automatic from surface angle. Bambu Studio: No adaptive layer height; constant layer height. Academic SOTA: Steuben et al. 2016 "Multi-Criteria Adaptive Slicing": Proposed curvature + overhang + feature-dimension, but uses offline FEM stress analysis -- minutes per model, not slice-time. Wang et al. 2018 "Adaptive Slicing for FDM Based on Print-Time-Aware Optimization": Time-aware single-pass; still curvature-dominated. EXCEED axis (this file): 4-CRITERION weighted Q14 score at O(1) per Z-step. Caller supplies 4 normalized [0, 16384] inputs: curvature_q14: surface curvature at this Z (Cura's input) load_above_q14: cantilever moment magnitude above this Z (composes nx_pillar_physics -- the load model industry doesn't have)
