Services

get_export (attribute)

Outputs

  • struct ::optitrack::ids::pubdata_s pubdata

    • boolean bodies

    • boolean markers

    • boolean anon

set_export (attribute)

Inputs

  • struct ::optitrack::ids::pubdata_s pubdata: Exported data

    • boolean bodies (default "1") Rigid bodies

    • boolean markers (default "0") Individual rigid body markers

    • boolean anon (default "0") Anonymous markers

get_local_port (attribute)

Outputs

  • unsigned short local_port

Get the UDP port on which the socket receiving data is bound.

See set_local_port (attribute).

set_local_port (attribute)

Inputs

  • unsigned short local_port (default "1510") local UDP port for listening

Change the default port on which the socket receiving data is bound.

When multiple instances of the component must run on the same host, each instance must use a different local UDP port. This service allows to change the default 1510 port to any value. It must be invoked before connect (activity) so that the selected value is taken into account.

Note
 The UDP socket is bound locally to a specific port in order to overcome a limitation of the Optitrack sotftware that cannot be told to stop sending data to a client. Not locally binding the socket would lead to an accumulation of streams to the same host after mutliple (re)connections to Optitrack, and a waste of bandwidth.

get_noise (attribute)

    • double pstddev
