Methods

Parameters:

// Output the canvas position of longitude/latitude (0, 0) every time the mouse moves.
var scene = widget.scene;
var ellipsoid = scene.globe.ellipsoid;
var position = bmgl.Cartesian3.fromDegrees(0.0, 0.0);
var handler = new bmgl.ScreenSpaceEventHandler(scene.canvas);
handler.setInputAction(function(movement) {
    console.log(scene.cartesianToCanvasCoordinates(position));
}, bmgl.ScreenSpaceEventType.MOUSE_MOVE);

Parameters:

// Clamp an entity to the underlying scene geometry
var position = entity.position.getValue(bmgl.JulianDate.now());
entity.position = viewer.scene.clampToHeight(position);

Throws

• DeveloperError : ClampToHeight僅在3D模式下受支持。
• DeveloperError : ClampToHeight需要深度紋理支持。檢查支架高度。

See:

• Scene#sampleHeight
• Scene#sampleHeightMostDetailed
• Scene#clampToHeightMostDetailed

Parameters:

var cartesians = [
    entities[0].position.getValue(bmgl.JulianDate.now()),
    entities[1].position.getValue(bmgl.JulianDate.now())
];
var promise = viewer.scene.clampToHeightMostDetailed(cartesians);
promise.then(function(updatedCartesians) {
    entities[0].position = updatedCartesians[0];
    entities[1].position = updatedCartesians[1];
}

Throws

• DeveloperError : ClampToHeightMostDetailed僅在3D模式下受支持。
• DeveloperError : ClamptoHeightMostDetailed需要深度紋理支持。檢查支架高度。

See:

• Scene#clampToHeight

scene = scene && scene.destroy();

Throws

• DeveloperError : 此對象已被銷毀，即調用destroy（）。

See:

• Scene#isDestroyed

Parameters:

var pickedObjects = scene.drillPick(new bmgl.Cartesian2(100.0, 200.0));

Throws

• DeveloperError : WindowPosition未定義。

Parameters:

// On mouse over, color the feature yellow.
handler.setInputAction(function(movement) {
    var feature = scene.pick(movement.endPosition);
    if (feature instanceof bmgl.BM3DTileFeature) {
        feature.color = bmgl.Color.YELLOW;
    }
}, bmgl.ScreenSpaceEventType.MOUSE_MOVE);

Parameters:

Throws

• DeveloperError : 不支持從深度緩沖區選取。檢查支持的選擇位置。

See:

• Scene#requestRenderMode

Parameters:

• DeveloperError : 樣品瓶需要深度紋理支持。檢查支持的樣本權重。

See:

• Scene#clampToHeight
• Scene#clampToHeightMostDetailed

    new bmgl.Cartographic(-1.31968, 0.69887),
    new bmgl.Cartographic(-1.10489, 0.83923)
];
var promise = viewer.scene.sampleHeightMostDetailed(positions);
promise.then(function(updatedPosition) {
    // positions[0].height and positions[1].height have been updated.
    // updatedPositions is just a reference to positions.
}
