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:

• 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. The clock angle, sometimes called azimuth, is the angle in the sensor's X-Y plane measured from the positive X-axis toward the positive Y-axis. The cone angle, sometimes called elevation, is the angle out of the X-Y plane along the positive Z-axis. This matrix is available to GLSL vertex and fragment shaders via czm_model and derived uniforms.

Model coordinate system for a custom 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. The default is true.

Default Value:

• true

See:

• CustomSensorVolume#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.

The default is false, meaning the sensor will not go through the ellipsoid.

Default Value:

• false
