Detailed Description
What the offset needs on top of the parameters every wmtk optimizer shares.
The optimization phase reuses wmtk::TetOptimizerMesh, so the quantities that phase reads – the target edge length and the split/collapse thresholds derived from it, the smoothing weights and pass count, the sizing-refinement knobs, the debug switch – come from wmtk::OptimizerParameters rather than being spelled out again here. The json keys are unchanged: length/length_rel feed the base's l/lr, smoothing_iterations feeds num_smoothing_passes, DEBUG_output feeds debug_output.
The bounding box stays here, as it does in every application: the base deliberately does not own it, because its type and meaning differ per application.
The documentation for this struct was generated from the following file:
