MNEMshDisplaySurface

Namespace: MNELIB  ·  Library: MNE Library

#include <mne/mne_msh_display_surface.h>

class MNELIB::MNEMshDisplaySurface

Replaces *mshDisplaySurface, mshDisplaySurfaceRec struct (analyze_types.c).

The MNE Msh Display FsSurface class holds information about a surface to be rendered.

Inheritance​

Public Methods​

MNEMshDisplaySurface()​

Constructs the MNEMshDisplaySurface.

~MNEMshDisplaySurface()​

Destroys the MNEMshDisplaySurface.

align_fiducials(head_dig, mri_dig, niter, scale_head, omit_dist, scales)​

Align MEG and MRI coordinate systems using fiducial points and ICP.

Parameters:

  • head_dig : FiffDigitizerData & MEG digitizer data (transformed in-place).

  • mri_dig : const FiffDigitizerData & MRI digitizer data with fiducial locations.

  • head_surf The scalp surface used for ICP.

  • niter : int Number of ICP iterations.

  • scale_head : int If non-zero, scale the head surface to match digitizer.

  • omit_dist : float Discard digitizer points farther than this from the surface (m).

  • scales : Eigen::Vector3f & If non-null, receives the per-axis scale factors applied.

Returns:

  • int — OK on success, FAIL on error.

get_head_scale(dig, mri_fid, scales)​

Compute a uniform head scale factor by fitting spheres.

discard_outlier_digitizer_points(d, maxdist)​

Mark digitizer points whose distance to the head surface exceeds maxdist.

calculate_digitizer_distances(dig, do_all, do_approx)​

Compute the distance from each active digitizer point to the head surface.

iterate_alignment_once(dig, nasion_weight, nasion_mri, last_step)​

Perform one iteration of ICP-like alignment.

rms_digitizer_distance(dig)​

Compute the RMS distance from active digitizer points to the head surface.

scale(scales)​

Scale a display surface's bounding box and all vertex positions.

decide_surface_extent(tag)​

Compute and store the axis-aligned bounding box and field-of-view radius by iterating all vertex positions.

Parameters:

  • tag : const QString & FsSurface name tag (used for debug logging).

decide_curv_display(name)​

Set the curvature display mode based on a surface type name.

Inflated, sphere, and white surfaces use overlay mode; others use none.

Parameters:

  • name : const QString & FsSurface type name.

setup_curvature_colors()​

Allocate and fill per-vertex color arrays using positive/negative curvature colors (if curvature overlay mode is on) or uniform gray.
