constructor

+ new IntersectionCase(intersectionEvents: IntersectionEvent[], base: Triangle, candidate: Triangle): IntersectionCase

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:15

Parameters:

Name	Type
intersectionEvents	IntersectionEvent[]
base	Triangle
candidate	Triangle

Returns: IntersectionCase

Properties

Private Readonly base

• base: Triangle

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:13

---

Private Readonly candidate

• candidate: Triangle

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:14

---

Private Readonly eventFingerprint

• eventFingerprint: number

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:15

---

Private Readonly intersectionEvents

• intersectionEvents: IntersectionEvent[]

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:12

Methods

Private _generateEventFingerprint

▸ _generateEventFingerprint(): number

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:55

The enum IntersectionEvent.EventType is designed so that the sum is unique for each combination of events

Returns: number

---

Private _sortEvents

▸ _sortEvents(events: IntersectionEvent[]): void

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:66

Sort events (historically) by their enum string names (Assuming the enum is sorted alphabetically for relevant events)

Parameters:

Name	Type	Description
events	IntersectionEvent[]	-

Returns: void

---

getBase

▸ getBase(): Triangle‹›

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:29

Returns: Triangle‹›

---

getCandidate

▸ getCandidate(): Triangle‹›

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:33

Returns: Triangle‹›

---

getEventFingerprint

▸ getEventFingerprint(): number

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:37

Returns: number

---

getEvents

▸ getEvents(): IntersectionEvent‹›[]

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:25

Returns: IntersectionEvent‹›[]

---

toString

▸ toString(): string

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:41

Returns: string

---

Static generateEventFingerprint

▸ generateEventFingerprint(eventTypes: EventType[]): number

Defined in src/util/polygon/triangulatingClipper/IntersectionCase.ts:8

Parameters:

Name	Type
eventTypes	EventType[]

Returns: number
