Detailed Description

Static factory for procedural mesh primitives.

All methods return fully constructed BrainSurface objects ready for rendering. This eliminates duplicated icosahedron / plate / barbell code that was spread across BrainView::onRowsInserted.

createBarbell()

std::shared_ptr< BrainSurface > MeshFactory::createBarbell ( const QVector3D & center, const QMatrix4x4 & orientation, const QColor & color, float size )

static

Create a barbell shape (two spheres connected by a thin rod), used for MEG gradiometers.

Parameters

[in]	center	World-space center.
[in]	orientation	3×3 rotation embedded in a 4×4 matrix (coil_trans).
[in]	color	Surface color.
[in]	size	Overall size scale in meters.

Returns

Shared pointer to the created BrainSurface.

Definition at line 222 of file meshfactory.cpp.

createBatchedSpheres()

std::shared_ptr< BrainSurface > MeshFactory::createBatchedSpheres ( const QVector< QVector3D > & positions, float radius, const QColor & color, int subdivisions = 1 )

static

Create a batched mesh of identical spheres at multiple positions (used for source space points, digitizer points, etc.).

All spheres are merged into a single BrainSurface for efficient rendering.

Parameters

[in]	positions	World-space positions for each sphere.
[in]	radius	Sphere radius in meters.
[in]	color	Sphere color.
[in]	subdivisions	Number of subdivision passes per sphere.

Returns

Shared pointer to the batched BrainSurface.

Definition at line 314 of file meshfactory.cpp.

createPlate()

std::shared_ptr< BrainSurface > MeshFactory::createPlate ( const QVector3D & center, const QMatrix4x4 & orientation, const QColor & color, float size )

static

Create a thin oriented rectangular plate (used for MEG magnetometers).

Parameters

[in]	center	World-space center.
[in]	orientation	3×3 rotation embedded in a 4×4 matrix (coil_trans).
[in]	color	Surface color.
[in]	size	Side length in meters (plate is size × size × thin).

Returns

Shared pointer to the created BrainSurface.

Definition at line 171 of file meshfactory.cpp.

createSphere()

std::shared_ptr< BrainSurface > MeshFactory::createSphere ( const QVector3D & center, float radius, const QColor & color, int subdivisions = 1 )

static

Create a subdivided icosahedron sphere.

Parameters

[in]	center	World-space center of the sphere.
[in]	radius	Radius in meters.
[in]	color	Surface color.
[in]	subdivisions	Number of subdivision passes (0 = 20 tris, 1 = 80 tris).

Returns

Shared pointer to the created BrainSurface.

Definition at line 138 of file meshfactory.cpp.

sphereVertexCount()

int MeshFactory::sphereVertexCount ( int subdivisions = 1 )

static

Number of vertices in a subdivided icosahedron (for picking calculations).

Parameters

[in]

subdivisions

Number of subdivision passes.

Returns

Number of vertices.
