AnalysisTerrainClipping

지형 절단면 분석 연산 및 영역 표시 클래스.
Terrain clipping analysis operation and area display class.
이 객체는 일반적으로 직접 인스턴스화되지 않습니다. AnalysisTerrainClipping.fromCartesianArray 사용을 권장합니다.
This object is normally not instantiated directly, use AnalysisTerrainClipping.fromCartesianArray.

new Ditap.AnalysisTerrainClipping(viewer, options)

Name Type Description
viewer DitapViewer 사용할 Ditap Viewer 인스턴스.
The DitapViewer instance to use.
options AnalysisExcavation.ConstructorOptions optional 초기화 옵션을 설명하는 객체.
An object describing initialization options.
Example:
const getUrlFromBase64 = (base64Data) => {
  const b64Data = base64Data;
  const byteCharacters = window.atob(b64Data);
  const byteNumbers = new Array(byteCharacters.length);

    byteNumbers[i] = byteCharacters.charCodeAt(i);
  }
  const byteArray = new Uint8Array(byteNumbers);
  const blob = new Blob([byteArray], { type: "image/png" });

  return URL.createObjectURL(blob);
};
