Detailed Description

Real-time sensor streaming lifecycle manager.

Manages real-time sensor data streaming via RtSensorDataController.

BrainView delegates all sensor streaming operations to this component, keeping its own code free of the RtSensorDataController lifecycle.

Member Function Documentation

colorsAvailable

void DISP3DLIB::RtSensorStreamManager::colorsAvailable ( const QString & surfaceKey, const QVector< uint32_t > & colors )

signal

Emitted when the streaming pipeline produces a new set of per-vertex colours for a sensor surface.

Parameters

[in]	surfaceKey	Key of the target surface.
[in]	colors	Per-vertex ABGR colour array.

isStreaming()

bool DISP3DLIB::RtSensorStreamManager::isStreaming ( ) const

inline

Returns

true while real-time sensor streaming is active.

Definition at line 97 of file rtsensorstreammanager.h.

modality()

QString DISP3DLIB::RtSensorStreamManager::modality ( ) const

inline

Returns

the active modality ("MEG" or "EEG"), or empty.

Definition at line 103 of file rtsensorstreammanager.h.

pushData()

void DISP3DLIB::RtSensorStreamManager::pushData

(

const Eigen::VectorXf &

data

)

Push a single measurement vector into the streaming queue.

Parameters

[in]

data

One sample of sensor values; ignored if no controller exists.

Definition at line 152 of file rtsensorstreammanager.cpp.

setAverages()

void DISP3DLIB::RtSensorStreamManager::setAverages

(

int

numAvr

)

Set the number of averages for smoothing.

Parameters

[in]

numAvr

Number of consecutive samples averaged per frame.

Definition at line 176 of file rtsensorstreammanager.cpp.

setColormap()

void DISP3DLIB::RtSensorStreamManager::setColormap

(

const QString &

name

)

Set the colormap used for colour mapping.

Parameters

[in]

name

Colormap name (e.g. "MNE", "Jet").

Definition at line 184 of file rtsensorstreammanager.cpp.

setInterval()

void DISP3DLIB::RtSensorStreamManager::setInterval

(

int

msec

)

Set the streaming playback interval in milliseconds.

Parameters

[in]

msec

Interval between streamed samples in milliseconds.

Definition at line 160 of file rtsensorstreammanager.cpp.

setLooping()

void DISP3DLIB::RtSensorStreamManager::setLooping

(

bool

enabled

)

Enable or disable looping of the streaming queue.

Parameters

[in]

enabled

True to replay the queue from the start when it ends.

Definition at line 168 of file rtsensorstreammanager.cpp.

startStreaming()

bool DISP3DLIB::RtSensorStreamManager::startStreaming	(	const QString &	modality,
		const SensorFieldMapper &	fieldMapper,
		const QMap< QString, std::shared_ptr< BrainSurface > > &	surfaces )

Start real-time sensor streaming for the given modality.

Reads mapping matrices, pick vectors, evoked data, and colourmap from the provided fieldMapper. Validates that the target surface key exists in surfaces.

Parameters

[in]	modality	"MEG" or "EEG".
[in]	fieldMapper	Sensor-field mapper with built mapping data.
[in]	surfaces	FsSurface map for target-surface validation.

Returns

true if streaming was started successfully.

Definition at line 45 of file rtsensorstreammanager.cpp.

stopStreaming()

void DISP3DLIB::RtSensorStreamManager::stopStreaming

(

)

Stop real-time sensor streaming.
