Function Documentation

◆ mneAnalyzeColor()

QRgb mneAnalyzeColor ( double v )

MNE analyze colormap: teal → blue → gray → red → yellow.

Port of mne_analyze_colormap(format='vtk') from MNE-Python. Input v is normalised to [0,1] where 0.5 corresponds to zero field.

Parameters

[in] v Normalised value in [0,1].

Returns: Packed QRgb colour.

◆ multiViewPresetIsPerspective()

bool multiViewPresetIsPerspective ( int preset )

Whether a preset is a perspective (free-rotate) camera rather than an orthographic-style fixed camera.

Definition at line 271 of file viewstate.cpp.

◆ multiViewPresetName()

QString multiViewPresetName ( int preset )

Human-readable name for a multi-view preset index (0–6).

Definition at line 225 of file viewstate.cpp.

◆ multiViewPresetOffset()

QQuaternion multiViewPresetOffset ( int preset )

Camera rotation quaternion for a multi-view preset index (0–6).

Definition at line 241 of file viewstate.cpp.

◆ normalizedVisualizationTarget()

int normalizedVisualizationTarget	(	int	target,
		int	maxIndex = 3 )

Clamp a visualization target index to [-1, maxIndex].

Parameters

[in]	target	Raw target index (-1 = single view, 0+ = multi pane).
[in]	maxIndex	Upper bound (inclusive). Defaults to 3 for backwards compatibility, but callers should pass viewportCount-1.

Definition at line 301 of file viewstate.cpp.

◆ perspectivePresetRotation()

QQuaternion perspectivePresetRotation ( )

Default perspective rotation quaternion used for the "Perspective" camera.

Definition at line 218 of file viewstate.cpp.

◆ shaderModeFromName()

ShaderMode shaderModeFromName ( const QString & name )

Convert a shader name ("Standard", "Holographic", "Anatomical") to enum.

Definition at line 308 of file viewstate.cpp.

◆ shaderModeName()

QString shaderModeName ( ShaderMode mode )

Convert a ShaderMode enum to display string.

Definition at line 318 of file viewstate.cpp.

◆ visualizationModeFromName()

VisualizationMode visualizationModeFromName ( const QString & name )

Convert a visualization mode name to enum.

Definition at line 327 of file viewstate.cpp.

◆ visualizationModeName()

QString visualizationModeName ( VisualizationMode mode )

Convert a VisualizationMode enum to display string.

Definition at line 337 of file viewstate.cpp.
