Methods

build()

Perform openness analysis.

clear()

Clear analysis.

destroy()

Destroy the resources held by the openness analysis object.

getViewDomeRatio(viewDomeType){Promise}

Obtain the proportion of openness analysis. This feature relies on openness analysis and requires ViewDome. build() to execute and obtain visual analysis results before it can be executed correctly

Name Type Description
viewDomeType ViewDomeType

Openness analysis type, if the parameter is VISIBLEDOME, returns the proportion of the visible part of the sky in the sky, and if the parameter is HIDDENDOME, returns the proportion of the invisible part of the sky in the sky.
Returns:
Type Description
Promise Return promise, obtain openness analysis upon successful analysis, return undefined upon failure
Example
let viewDome = new SuperMap3D.ViewDome(scene);
viewDome.viewPosition = new SuperMap3D.Cartesian3(X, X, X);
viewDome.build(); // Perform openness analysis first

// After obtaining the visualization result of openness analysis, call the API to get the openness ratio
let promise = viewDome.getViewDomeRatio(SuperMap3D.ViewDomeType.VISIBLEDOME);
prmomise.then((resultRatio) => {
 console.log(resultRatio);
});
