class MNELIB::MNEMshLightSet

Collection of lights defining the lighting setup for 3-D rendering.

Public Methods​

MNEMshLightSet()​

Constructs an empty MNEMshLightSet.

MNEMshLightSet(other)​

operator=(other)​

MNEMshLightSet()​

operator=()​

~MNEMshLightSet()​

Destructor.

nlight()​

Returns the number of lights in the set.

Returns:

  • int — Number of owned light objects.

Example​

No example of its own: Lighting rig of the legacy MNE-C mesh viewer held by MNEMshDisplaySurfaceSet; UI state with no computation to demonstrate.

It is exercised by:

src/examples/ex_mne_api/main.cpp
// Total solid angle seen from a point: 4 pi inside a closed surface, 0 outside
auto skull = MNESurface::read_bem_surface2(bemFile.fileName(), FIFFV_BEM_SURF_ID_BRAIN, true);
skull->compute_surface_cm();
const double inside = skull->sum_solids(Map<const Vector3f>(skull->cm)) / (4.0 * M_PI);
const double outside = skull->sum_solids(Vector3f(0.0f, 0.0f, 0.2f)) / (4.0 * M_PI);

// The same surface as an MNE-C viewer display surface
MNEMshDisplaySurfaceSet display;
display.add_bem_surface(bemFile.fileName(), FIFFV_BEM_SURF_ID_BRAIN, "inner skull", 1, 1); // checks closure
const MNEMshDisplaySurface& shown = *display.surfs[0];
