bufferUsage :BufferUsage

DOC_TBA

Default Value:

• BufferUsage.STATIC_DRAW

intersectionColor :Color

The color of the polyline where the sensor outline intersects the central body. The default is Color.WHITE.

Default Value:

• Color.WHITE

See:

• RectangularPyramidSensorVolume#showIntersection

intersectionWidth :Number

The approximate pixel width of the polyline where the sensor outline intersects the central body. The default is 5.0.

Default Value:

• 5.0

See:

• CustomSensorVolume#showIntersection

material :Material

The surface appearance of the sensor. This can be one of several built-in Material objects or a custom material, scripted with Fabric.

The default material is Material.ColorType.

Example

// 1. Change the color of the default material to yellow
sensor.material.uniforms.color = new Color(1.0, 1.0, 0.0, 1.0);

// 2. Change material to horizontal stripes
sensor.material = Material.fromType(scene.getContext(), Material.StripeType);

Default Value:

• Material.fromType(undefined, Material.ColorType)

See:

• Fabric

modelMatrix :Matrix4

The 4x4 transformation matrix that transforms this sensor from model to world coordinates. In it's model coordinates, the sensor's principal direction is along the positive z-axis. Half angles measured from the principal direction and in the direction of the x-axis and y-axis define the extent of the rectangular cross section. This matrix is available to GLSL vertex and fragment shaders via czm_model and derived uniforms.

Model coordinate system for a sensor

Example

// The sensor's vertex is located on the surface at -75.59777 degrees longitude and 40.03883 degrees latitude.
// The sensor's opens upward, along the surface normal.
var center = ellipsoid.cartographicToCartesian(Cartographic.fromDegrees(-75.59777, 40.03883));
sensor.modelMatrix = Transforms.eastNorthUpToFixedFrame(center);

Default Value:

• Matrix4.IDENTITY

See:

• czm_model

radius :Number

DOC_TBA

Default Value:

• Number.POSITIVE_INFINITY

show :Boolean

true if this sensor will be shown; otherwise, false

Default Value:

• true

showIntersection :Boolean

When true, a polyline is shown where the sensor outline intersections the central body.

Default Value:

• true

See:

• RectangularPyramidSensorVolume#intersectionColor

showThroughEllipsoid :Boolean

Determines if a sensor intersecting the ellipsoid is drawn through the ellipsoid and potentially out to the other side, or if the part of the sensor intersecting the ellipsoid stops at the ellipsoid.

Default Value:

• false

xHalfAngle :Number

DOC_TBA

Default Value:

• CesiumMath.PI_OVER_TWO

See:

• RectangularPyramidSensorVolume#yHalfAngle

yHalfAngle :Number

DOC_TBA

Default Value:

• CesiumMath.PI_OVER_TWO

See:

• RectangularPyramidSensorVolume#xHalfAngle
