generate_sparse_infill_polylines_for_anchoring()

Polylines Slic3r::Layer::generate_sparse_infill_polylines_for_anchoring ( const FillAdaptive::RegionOctrees * fill_octrees, FillLightning::Generator * lightning_generator ) const

inherited

Generate sparse-infill polylines for anchoring/analysis purposes.

This produces the geometric polylines of internal sparse infill for the current layer (using the same infill pattern, angle, rotation template, and spacing that normal slicing would use), but it does not create extrusion entities.

The returned polylines are consumed by internal-bridge detection on the next layer to derive anchor lines and compute the bridge direction over sparse infill.

Notes:

• Only stInternal surfaces are considered.
• Rotation templates (e.g. sparse_infill_rotate_template) are applied so the anchors reflect the actual infill orientation.
• For lightning/adaptive patterns, the respective generators are wired so their polylines match the final infill layout.
