Namespace: MNELIB  ·  Library: MNE Library

#include <mne/mne_msh_light.h>

class MNELIB::MNEMshLight

Replaces *mshLight,mshLightRec struct (analyze_types.c).

Single light source with position, color, and state for 3-D surface rendering.

Public Methods​

MNEMshLight()​

Constructs the MNEMshLight.

MNEMshLight(p_mneMshLight)​

Copy Constructs of the MNEMshLight.

Parameters:

  • p_mneMshLight : const MNEMshLight & Light to copy.

MNEMshLight(state, posX, posY, posZ, diffX, diffY, diffZ)​

Constructs the MNEMshLight.

Parameters:

  • state : int Non-zero to switch the light on.

  • posX : float Light position x coordinate.

  • posY : float Light position y coordinate.

  • posZ : float Light position z coordinate.

  • diffX : float Diffuse intensity, red component.

  • diffY : float Diffuse intensity, green component.

  • diffZ : float Diffuse intensity, blue component.

~MNEMshLight()​

Destroys the MNEMshLight.

Example​

No example of its own: Light 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];
