StcLoadingWorker pulls the LH and RH .stc files from disk in a background thread, parses them into an INVLIB::InvSourceEstimate per hemisphere and builds the sparse vertex-to-source interpolation matrix using GeometryInfo::scdc / Interpolation::createInterpolationMat with a configurable geodesic cancel distance.

On completion the controller signals the GUI to attach the data to the cortical surfaces, after which scrubbing and playback are served by DISP3DLIB::SourceEstimateOverlay without any further I/O.
