RtSourceDataWorker

Namespace: DISP3DLIB  ·  Library: 3D Display Library

#include <disp3D/rtsourcedataworker.h>

class DISP3DLIB::RtSourceDataWorker

RtSourceDataWorker processes incoming source estimate data in a background thread.

It manages a data queue, performs averaging, applies interpolation matrices, and converts source values to per-vertex ABGR colors for rendering.

This worker is driven by a timer in the RtSourceDataController.

Background worker for real-time source estimate streaming.

Inheritance​

Public Methods​

RtSourceDataWorker(parent)​

Constructor.

Parameters:

  • parent : *QObject ** Parent QObject.

addData(data)​

Add a new source estimate data vector to the streaming queue.

The vector contains source values for all sources (LH + RH concatenated).

Parameters:

  • data : const Eigen::VectorXd & Source activity vector (nSources x 1).

clear()​

Clear all queued data.

setInterpolationMatrixLeft(mat)​

Set the interpolation matrix for the left hemisphere.

Parameters:

  • mat : QSharedPointer< Eigen::SparseMatrix< float > > Sparse interpolation matrix (nVertices x nSourcesLH).

setInterpolationMatrixRight(mat)​

Set the interpolation matrix for the right hemisphere.

Parameters:

  • mat : QSharedPointer< Eigen::SparseMatrix< float > > Sparse interpolation matrix (nVertices x nSourcesRH).

setNumberAverages(numAvr)​

Set the number of samples to average before emitting.

Parameters:

  • numAvr : int Number of averages (1 = no averaging).

setColormapType(name)​

Set the colormap type used for color conversion.

Parameters:

  • name : const QString & Colormap name ("Hot", "Jet", "Viridis", "Cool", "RedBlue").

setThresholds(min, mid, max)​

Set the threshold values for normalization.

Parameters:

  • min : double Lower threshold (values below are transparent).

  • mid : double Mid-point threshold (fade-in range).

  • max : double Upper threshold (values above are clamped).

setLoopState(enabled)​

Enable or disable looping (replay from beginning when queue is exhausted).

Parameters:

  • enabled : bool True to enable looping.

setSFreq(sFreq)​

Set the sampling frequency of the incoming data.

Parameters:

  • sFreq : double Sampling frequency in Hz.

setStreamSmoothedData(bStreamSmoothedData)​

Toggle between emitting interpolated color data (smoothed) and raw source values split by hemisphere.

When enabled (default), streamData() performs interpolation + colormap conversion and emits newRtSmoothedData(). When disabled, it emits newRtRawData() with the raw source values per hemisphere, which can be used for GPU-side interpolation.

Parameters:

  • bStreamSmoothedData : bool True for smoothed colors (default), false for raw.

setSurfaceColor(baseColorsLh, baseColorsRh)​

Set the base surface colors for both hemispheres.

Sub-threshold vertices will display these colors instead of being transparent.

Parameters:

  • baseColorsLh : const QVector< uint32_t > & Per-vertex ABGR colors for the left hemisphere.

  • baseColorsRh : const QVector< uint32_t > & Per-vertex ABGR colors for the right hemisphere.
