Module bridge 

Bridging two boundary loops with a triangle tube.

bridge_loops stitches a tube between two boundary loops identified by LoopId. The correspondence is a minimum-area dynamic program over the loop-by-loop grid with a full start search, so loops of different lengths zip without twist. The loops must wind in opposite directions (their Newell vectors must oppose); same-winding loops admit no outward tube that is manifold at both rims and are rejected. The whole strip is planned first and committed through one Transaction, so the call is atomic.

Structs

BridgeOptions

Options for bridge_loops.

Constants

BRIDGE_DEFAULT_MAX_EDGES

Default cap on each loop’s length in vertices. Explicit max_edges overrides it; the dynamic program costs O(starts x cells), so raising the bound past a few hundred gets slow before it gets big.

Functions

bridge_loops

Stitches a tube between the two loops in options.
