X3D Reference



ReceiverPdu is a networked Protocol Data Unit (PDU) information node that transmits the state of radio frequency (RF) receivers modeled in a simulation.

The ReceiverPdu node belongs to the DIS component and its container field is children. It is available since X3D version 3.0 or later.


* Derived from multiple interfaces.


SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFVec3f [ ] bboxSize -1 -1 -1

Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.


Can be useful for collision computations or inverse-kinematics (IK) engines.

SFVec3f [ ] bboxCenter 0 0 0

Bounding box center: optional hint for position offset from origin of local coordinate system.

SFBool [in, out] enabled TRUE

Enables/disables the sensor node.

SFBool [out] isActive

Have we had a network update recently?.

SFString [in, out] address "localhost"

Multicast network address, or else "localhost"

SFInt32 [in, out] applicationID 1 [0,65535]

Each simulation application that can respond to simulation management PDUs needs to have a unique applicationID.

SFInt32 [in, out] entityID [0,65535]

EntityID unique ID for entity within that application.

SFString [in, out] multicastRelayHost ""

Fallback server address if multicast not available locally. For example: track.nps.edu.

SFInt32 [in, out] multicastRelayPort

Fallback server port if multicast not available locally. For example: 8010.

SFString [in, out] networkMode "standAlone" ["standAlone"|

Whether this entity is ignoring the network, sending DIS packets to the network, or receiving DIS packets from the network. (1) standAlone: ignore network but still respond to events in local scene. (2) networkReader: listen to network and read PDU packets at readInterval, act as remotely linked copy of entity. (3) networkWriter: send PDU packets to network at writeInterval, act as master entity. Default value "standAlone" ensures that DIS network activation within a scene as networkReader or networkWriter is intentional.


Do not wrap extra quotation marks around these SFString enumeration values, since "quotation" "marks" are only used for MFString values. Network activity may have associated security issues.

SFInt32 [in, out] port

Multicast network port, for example: 62040.

SFInt32 [in, out] radioID

Identifies a particular radio within a given entity.

SFFloat [in, out] readInterval 0.1

Seconds between read updates, 0 means no reading.

SFFloat [in, out] receivedPower

ReceivedPower indicates radio frequency (RF) power received, in units of decibel-milliwatts (dBm), after applying any propagation loss and antenna gain

SFInt32 [in, out] receiverState

ReceiverState indicates if receiver is currently idle or busy via one of these enumerated values: 0 = off, 1 = on but not receiving, or 2 = on and receiving.

SFBool [in, out] rtpHeaderExpected FALSE

Whether RTP headers are prepended to DIS PDUs.

SFInt32 [in, out] siteID

Simulation/exercise siteID of the participating LAN or organization.

SFInt32 [in, out] transmitterApplicationID 1

Simulation/exercise transmitterApplicationID is unique for transmitter application at that site. Each simulation application that can respond to simulation management PDUs needs to have a unique applicationID.

SFInt32 [in, out] transmitterEntityID

Simulation/exercise transmitterEntityID is a unique ID for a single entity within that application.

SFInt32 [in, out] transmitterRadioID

Identifies a particular radio within a given entity.

SFInt32 [in, out] transmitterSiteID

Simulation/exercise transmitterSiteID of the participating LAN or organization.

SFInt32 [in, out] whichGeometry 1

Select geometry to render: -1 for no geometry, 0 for text trace, 1 for default geometry, (optional) higher values to render different states.

SFFloat [in, out] writeInterval 1

Seconds between write updates, 0 means no writing (sending).

SFBool [out] isNetworkReader

Whether networkMode="remote" (listen to network as copy of remote entity)

SFBool [out] isNetworkWriter

Whether networkMode="master" (output to network as master entity at writeInterval)

SFBool [out] isRtpHeaderHeard

Whether incoming DIS packets have an RTP header prepended.

SFBool [out] isStandAlone

Whether networkMode="local" (ignore network but still respond to local events)

SFTime [out] timestamp

DIS timestamp in X3D units (seconds since 1 January 1970).



  • ReceiverPdu packets use the IEEE Distributed Interactive Simulation (DIS) protocol.
  • Include <component name='DIS' level='1'/>
