RtSensorInterpolationMatWorker

Namespace: DISP3DLIB  ·  Library: 3D Display Library

#include <disp3D/rtsensorinterpolationmatworker.h>

class DISP3DLIB::RtSensorInterpolationMatWorker

RtSensorInterpolationMatWorker computes dense sensor-to-surface field-mapping matrices in a background thread.

This worker encapsulates the expensive FieldMap::computeMegMapping() and computeEegMapping() calls that were previously performed synchronously on the main thread inside BrainView::buildSensorFieldMapping().

The worker stores all relevant parameters (evoked info, surface geometry, transforms, etc.) and recomputes the mapping matrices when any parameter changes. It emits newMappingMatrixAvailable() when a new matrix is ready.

Thread-safety: all public setters are mutex-protected and schedule a recomputation via the computeMapping() slot.

Background worker for computing sensor field mapping matrices.

Inheritance​

Public Methods​

RtSensorInterpolationMatWorker(parent)​

Constructor.

Parameters:

  • parent : *QObject ** Parent QObject.

setEvoked(evoked)​

Set the evoked data that contains channel info and sensor definitions.

Parameters:

setTransform(trans, applySensorTrans)​

Set the head-to-MRI coordinate transform.

Parameters:

  • trans : const FiffCoordTrans & The transform.

  • applySensorTrans : bool Whether to apply the transform.

setMegFieldMapOnHead(onHead)​

Set whether the MEG field should be mapped onto the head (BEM) surface rather than the helmet surface.

Parameters:

  • onHead : bool True to map onto head.

setMegSurface(surfaceKey, vertices, normals, triangles)​

Set the surface geometry used for MEG field mapping.

This must include vertex positions and normals (for MEG).

Parameters:

  • surfaceKey : const QString & The key identifying the surface.

  • vertices : const Eigen::MatrixX3f & Vertex positions (nVerts x 3).

  • normals : const Eigen::MatrixX3f & Vertex normals (nVerts x 3).

  • triangles : const Eigen::MatrixX3i & Triangle indices (nTris x 3).

setEegSurface(surfaceKey, vertices)​

Set the surface geometry used for EEG field mapping.

Parameters:

  • surfaceKey : const QString & The key identifying the surface.

  • vertices : const Eigen::MatrixX3f & Vertex positions (nVerts x 3).

setBadChannels(bads)​

Set the bad channels.

Triggers recomputation if changed.

Parameters:

  • bads : const QStringList & List of bad channel names.
