class MNELIB::MNEBemSurface

BEM surface geometry information.

Inherits core geometry (vertices, normals, triangles, neighbors) from MNESurface/MNESurfaceOrVolume. Adds BEM-specific computed triangle metadata (centers, normals, areas) and I/O.

BEM surface provides geometry information

Inheritance​

Public Methods​

MNEBemSurface()​

Constructors the bem surface.

MNEBemSurface(p_MNEBemSurface)​

Copy constructor.

Parameters:

  • p_MNEBemSurface : const MNEBemSurface & BEM surface which should be copied.

~MNEBemSurface()​

Destroys the BEM surface.

clear()​

Initializes the BEM surface.

addTriangleData()​

Definition of the mne_add_triangle_data function in mne_add_geometry_info.c.

Completes triangulation info

Returns:

  • bool — true if succeeded, false otherwise.

add_geometry_info()​

Add vertex normals and neighbourhood information.

Returns:

  • bool — true if succeeded, false otherwise.

addVertexNormals()​

Definition of the addVertexNormals function in mne_add_geometry_info.c.

Completes triangulation info

Returns:

  • bool — true if succeeded, false otherwise.

writeToStream(p_pStream)​

Writes the bem surface to a FIFF stream.

Parameters:

  • p_pStream : *FiffStream ** The stream to write to.

Static Methods​

id_name(id)​

Map bem id integers to human-readable names.

Parameters:

  • frame The bem id integer.

Returns:

  • QString — Human readable form of the bem id.

makeScalpSurfaces(outerSkin, targetVertices)​

Decimate the outer skin surface to the target vertex counts using iterative edge collapse simplification.

Parameters:

  • outerSkin : const MNEBemSurface & The outer skin BEM surface to decimate.

  • targetVertices : const QList< int > & List of target vertex counts (default: {2562, 10242, 40962}).

Returns:

  • QList< MNEBemSurface > — A list of decimated BEM surfaces, one per target resolution.
