Detailed Description

The factory implements buildSolid() to produce a G4VSolid. Logical and physical construction are provided by the base class and therefore follow the same material lookup, visualization attribute, and placement rules used by other factories.

Member Function Documentation

buildSolid()

G4VSolid * G4CadSystemFactory::buildSolid ( const GVolume * s, std::unordered_map< std::string, G4Volume * > * g4s )

overrideprotectedvirtual

Parameters

s	GEMC volume definition. The file path is read from s->getDescription().
g4s	Map holding cached G4Volume wrappers.

Returns

Pointer to the created solid, or nullptr if dependencies are missing or format unsupported.

The method performs:

• dependency checks (copy/boolean operands) through the shared base logic
• wrapper retrieval/creation for caching
• extension-based dispatch to the CADMesh reader

Recognized extensions are:

• ply
• stl

Any other extension results in a warning and nullptr.

Implements G4ObjectsFactory.

className()

std::string_view G4CadSystemFactory::className ( ) const

inlineoverridevirtual

Returns

"G4CadSystemFactory".

Implements G4ObjectsFactory.

Definition at line 48 of file cadSystemFactory.h.

G4ObjectsFactory()

G4ObjectsFactory::G4ObjectsFactory ( const std::shared_ptr< GOptions > & g )

inlineexplicit

Parameters

g	Shared option set used to initialize the logging base and other behaviors.
