About curtains
Curtains are 3D objects that can be viewed in a scene. Curtains can be created from:
Single beam echogram curtains
A single beam echogram curtain is a 3D representation of all or part of a single beam echogram (of data type Power, Sv, TS or Unspecified dB). A curtain is made up of one or more curtain segments. The size of each curtain segment is defined by the number of pings it represents and is specified at the time of creation.
Single beam echogram curtains can be automatically updated when new data arrives. This is very useful for live viewing in 3D.
Curtains are not supported for wideband data of complex data type, however the Type conversion operator may be used to convert complex data types to a data type suitable for a curtain.
Mulitbeam ping curtains
A multibeam ping curtain is a 3D representation of a single ping from a multibeam echogram. Multibeam ping curtains are generally part of a multibeam ping curtain group.
Exports and properties
