PolygonEntity

면 엔티티 표시 클래스.
Polygon entity display class.

new Ditap.PolygonEntity(viewer, positions)

Name Type Description
viewer DitapViewer 사용할 Ditap Viewer 인스턴스.
The DitapViewer instance to use.
positions Array.<Cartesian3> optional 면 생성을 위한 Cartesian 좌표 배열.
Cartesians for line creation.
Example:
// 샌드캐슬 예제 'DiTAP - Polygon Entity' 참조

const viewer = new DitapViewer("ditapContainer");

// 1. 위치 지정 없이 객체 생성. (InteractionPolygonEntity를 통해 점 엔티티 표시.)
const PolygonEntity = new Ditap.PolygonEntity(viewer);

const InteractionPolygonEntity = new Ditap.InteractionPolygonEntity();
InteractionPolygonEntity.PolygonEntity = PolygonEntity;

// 2. 위치 지정하여 객체 생성. (InteractionPolygonEntity 통한 수정 불가.)
const position1 = new Ditap.Cartesian3.fromDegrees(
 126.9777639655642,
 37.56676148138595
);

const position2 = new Ditap.Cartesian3.fromDegrees(
 126.97776396708979,
 37.56658104096736
);

const position3 = new Ditap.Cartesian3.fromDegrees(
 126.97794279498576,
 37.566579036698215
);

const position4 = new Ditap.Cartesian3.fromDegrees(
 126.9779494810781,
 37.56676163390728
);

const PolygonEntity = new Ditap.PolygonEntity(viewer, [position1, position2, position3, position4]);
