Method
Inner-Fit Polygon
Geometric primitive describing where a piece fits inside the stock boundary.
Also called: Inner-Fit Polygon · IFP · Inner-Fit Rectangle · 내부 적합 폴리곤
The primitive responsible for containment, one of the two geometric axes of
irregular nesting (classified as a method in v1). The IFP encodes the region
of reference-point positions for which a piece lies entirely inside the stock
boundary, turning "does it fit inside the sheet?" into a point-location query.
It pairs with the No-Fit Polygon, which handles
piece-to-piece overlap; see Bennell & Oliveira (2008) for the standard account.

| shares method withNo-Fit Polygon | The Inner-Fit Polygon (IFP) gives the region where a piece fits inside the sheet boundary while the No-Fit Polygon (NFP) handles piece-to-piece overlap — complementary geometric primitives that reduce irregular-nesting placement to point-location queries. | E2 | A |
