DebugCameraPrimitive

DebugCameraPrimitive是CesiumJS中一种用来检测相机视锥体的图形元素。

安装

DebugCameraPrimitive包含在CesiumJS的核心库中,因此不需要单独安装或导入。

使用

要在场景中添加DebugCameraPrimitive,首先需要创建它:

const debugCamera = new Cesium.DebugCameraPrimitive({
    camera: viewer.camera,
    color: Cesium.Color.YELLOW,
    updateOnChange :true
});

在上面的例子中,我们创建了一个yellow颜色的DebugCameraPrimitive,该元素将监测当前场景中的相机。

您还可以为DebugCameraPrimitive指定其他属性,例如线宽、线型和闪烁状态:

const debugCamera = new Cesium.DebugCameraPrimitive({
    camera: viewer.camera,
    color: Cesium.Color.YELLOW,
    outlineColor: Cesium.Color.RED,
    outlineWidth: 4,
    mode: Cesium.DebugCameraPrimitiveMode.TRIANGLES,
    flashOnHide: true,
    flashTime: 2000,
    updateOnChange :true
});

这个例子中,我们为DebugCameraPrimitive提供了一些新的属性。outlineColor和outlineWidth分别设置了轮廓线的颜色和宽度。mode属性指定了DebugCameraPrimitive模式的类型(这里是三角形模式)。flashOnHide和flashTime属性控制了在隐藏DebugCameraPrimitive元素时是否闪烁,以及闪烁的持续时间。

最后一个属性,updateOnChange,设置DebugCameraPrimitive是否应该在相机位置改变时自动更新。

方法

以下是DebugCameraPrimitive支持的方法:

destroy()

从场景中删除DebugCameraPrimitive元素。

debugCamera.destroy();

show(boolean)

指示DebugCameraPrimitive元素是否应该在场景中可见。

debugCamera.show(true);

isDestroyed()

如果DebugCameraPrimitive元素被销毁,则返回true。

if (debugCamera.isDestroyed()) {
    console.log('DebugCameraPrimitive element has been destroyed!');
}

属性

以下是DebugCameraPrimitive支持的属性:

camera

指定要监测的相机。

debugCamera.camera = new Cesium.Camera(scene);

color

指定DebugCameraPrimitive元素的颜色。

debugCamera.color = Cesium.Color.YELLOW;

outlineColor

指定DebugCameraPrimitive元素的轮廓线颜色。

debugCamera.outlineColor = Cesium.Color.RED;

outlineWidth

指定DebugCameraPrimitive元素轮廓线的宽度。

debugCamera.outlineWidth = 4;

mode

指定DebugCameraPrimitive元素的显示模式。

debugCamera.mode = Cesium.DebugCameraPrimitiveMode.TRIANGLES;

可选值:

  • Cesium.DebugCameraPrimitiveMode.LINES(默认)
  • Cesium.DebugCameraPrimitiveMode.TRIANGLES

flashOnHide

指定DebugCameraPrimitive元素在隐藏时是否应该闪烁。

debugCamera.flashOnHide = true;

flashTime

指定DebugCameraPrimitive元素闪烁的时间(以毫秒为单位)。

debugCamera.flashTime = 2000;

updateOnChange

指定DebugCameraPrimitive元素是否应该在相机位置改变时自动更新。

debugCamera.updateOnChange  = true;
