Detailed Description

Data model for stereotactic depth electrode (sEEG) visualization.

Holds electrode shaft definitions and contact metadata, and generates CPU-side geometry (vertices/indices) that a QRhi-based renderer can upload to the GPU.

Member Function Documentation

boundingBoxMax()

QVector3D ElectrodeObject::boundingBoxMax

(

)

const

Returns

Axis-aligned bounding box maximum corner (with contact-radius padding).

Definition at line 332 of file electrodeobject.cpp.

boundingBoxMin()

QVector3D ElectrodeObject::boundingBoxMin

(

)

const

Returns

Axis-aligned bounding box minimum corner (with contact-radius padding).

Definition at line 325 of file electrodeobject.cpp.

clearSelection()

void ElectrodeObject::clearSelection

(

)

Clear all contact selections.

Definition at line 169 of file electrodeobject.cpp.

contactInstanceCount()

uint32_t ElectrodeObject::contactInstanceCount

(

)

const

Returns

Number of contact instances for instanced draw.

Definition at line 489 of file electrodeobject.cpp.

generateContactInstances()

void ElectrodeObject::generateContactInstances

(

QVector< float > &

instanceData

)

const

Generate per-instance data for contact spheres. Per instance: position (3) + radius (1) + color RGBA (4) + selected flag (1) = 9 floats.

Parameters

[out]

instanceData

Flat float buffer.

Definition at line 298 of file electrodeobject.cpp.

generateShaftGeometry()

void ElectrodeObject::generateShaftGeometry	(	QVector< float > &	vertices,
		QVector< unsigned int > &	indices,
		int	cylinderSides = 16 ) const

Generate interleaved vertex + index data for all shaft cylinders. Each vertex: position (3 floats) + normal (3 floats) = 6 floats.

Parameters

[out]	vertices	Vertex buffer (position + normal interleaved).
[out]	indices	Index buffer (triangles).
[in]	cylinderSides	Number of sides for the cylinder cross-section.

Definition at line 188 of file electrodeobject.cpp.

indexBuffer()

QRhiBuffer * ElectrodeObject::indexBuffer

(

)

const

Returns

Shaft index buffer.

Definition at line 468 of file electrodeobject.cpp.

instanceBuffer()

QRhiBuffer * ElectrodeObject::instanceBuffer

(

)

const

Returns

Contact instance buffer (9 floats/instance).

Definition at line 475 of file electrodeobject.cpp.

selectContact()

void ElectrodeObject::selectContact

(

const QString &

name

)

Select a contact by name. Clears the previous selection.

Parameters

[in]

name

Contact name to select.

Definition at line 146 of file electrodeobject.cpp.

selectedContact()

QString ElectrodeObject::selectedContact

(

)

const

Returns

Name of the currently selected contact, or empty string if none.

Definition at line 181 of file electrodeobject.cpp.

setContactValues()

void ElectrodeObject::setContactValues	(	const QMap< QString, float > &	values,
		const QColor &	minColor = Qt::blue,
		const QColor &	maxColor = Qt::red )

Apply per-contact scalar overlay values and map them to a color gradient.

Parameters

[in]	values	Map of contact name -> scalar value.
[in]	minColor	Color for the minimum value (default: blue).
[in]	maxColor	Color for the maximum value (default: red).

Definition at line 115 of file electrodeobject.cpp.

setShafts()

void ElectrodeObject::setShafts

(

const QVector< ElectrodeShaft > &

shafts

)

Set electrode data from shaft definitions.

Parameters

[in]

shafts

Vector of electrode shafts.

Definition at line 88 of file electrodeobject.cpp.

shaftIndexCount()

uint32_t ElectrodeObject::shaftIndexCount

(

)

const

Returns

Total number of contacts across all shafts.

Definition at line 105 of file electrodeobject.cpp.

updateBuffers()

void ElectrodeObject::updateBuffers	(	QRhi *	rhi,
		QRhiResourceUpdateBatch *	u )

Update GPU buffers (shaft vertex/index, contact instance) via QRhi.

Parameters

[in]	rhi	Pointer to QRhi instance.
[in]	u	Resource update batch.

Definition at line 390 of file electrodeobject.cpp.

vertexBuffer()

QRhiBuffer * ElectrodeObject::vertexBuffer

(

)

const

Returns

Shaft vertex buffer (position + normal interleaved, 6 floats/vertex).

Definition at line 461 of file electrodeobject.cpp.
