STK Components 二次开发-地面站传感器

上一篇我们说了创建地面站，那么这次我们在地面站添加一些特效。

创建地面站

cs 复制代码

var locationPoint1 = new PointCartographic(m_earth, new Cartographic(Trig.DegreesToRadians(117.17066), Trig.DegreesToRadians(31.84056), 240.359));
m_facility = new Platform
{
	Name = "DMZ",
	LocationPoint = locationPoint1,
	// Orient the facility using East-North-Up (ENU) axes.
	OrientationAxes = new AxesEastNorthUp(m_earth, locationPoint1),
};

// Set the identifier for the facility in the CZML document. 
m_facility.Extensions.Add(new IdentifierExtension("DSS"));

// Configure a glTF model for the facility.
m_facility.Extensions.Add(new ModelGraphicsExtension(new ModelGraphics
{
	// Link to a binary glTF file.
	Model = new CesiumResource(GetModelUri("facility.glb"), CesiumResourceBehavior.LinkTo),
	RunAnimations = false,
	HeightReference = CesiumHeightReference.ClampToGround,
}));

// Configure label for AGI HQ.
m_facility.Extensions.Add(new LabelGraphicsExtension(new LabelGraphics
{
	Text = m_facility.Name,
	FillColor = Color.White,
	Font = new ConstantCesiumProperty<string>("20px"),
	// Only show label when camera is far enough from the satellite,
	// to avoid visually clashing with the model.
	DistanceDisplayCondition = new Bounds(1000.0, double.MaxValue),
	HeightReference = CesiumHeightReference.ClampToGround,
}));

2.创建传感器

// Configure graphical display of the sensor dome.

// Define a rotating axes.

// Define a rotation around X.
UnitQuaternion quaternion = new UnitQuaternion(new AngleAxisRotation(Math.PI / 3.0, UnitCartesian.UnitX));
// Define an angular offset for the rotating axes.
var rotatedOffsetAxes = new AxesFixedOffset(rotatingAxes, quaternion);

m_rotatingSensor = new Platform

	LocationPoint = locationPoint,
	OrientationAxes = rotatedOffsetAxes
};

// Set the identifier for the sensor in the CZML document. 
m_rotatingSensor.Extensions.Add(new IdentifierExtension("RotatingSensor"));

// Define the sensor geometry.
m_rotatingSensor.Extensions.Add(new FieldOfViewExtension(new RectangularPyramid
{
	XHalfAngle = Trig.DegreesToRadians(30),
	YHalfAngle = Trig.DegreesToRadians(30),
	Radius = 10000.0,
}));

// Configure graphical display of the sensor.
m_rotatingSensor.Extensions.Add(new FieldOfViewGraphicsExtension(new SensorFieldOfViewGraphics
{

	{

	ShowEllipsoidHorizonSurfaces = true,
}));
