Detailed Description

Firewall bridge between the DD4hep plugin TU and G4OCCT/OCCT.

The DD4hep/ROOT headers and OCCT headers cannot be included together in one translation unit due to the ROOT-vs-OCCT Printf return-type collision and Handle macro interactions, so this bridge keeps the include worlds separate.

This header must not pull in either DD4hep/ROOT or G4OCCT/OCCT.

Function Documentation

G4OCCT_ImportSTEPAssembly()

int G4OCCT_ImportSTEPAssembly	(	const std::string &	path,
		const std::map< std::string, G4Material * > &	materials,
		const std::string &	detectorName,
		const std::vector< std::string > &	sensitiveNames
	)

Import a STEP assembly, build the G4OCCTAssemblyVolume, register it in G4OCCTAssemblyRegistry under detectorName, and return the number of constituent solids found. The assembly lifetime is managed by the registry.

Parameters

path	Path to the STEP file.
materials	Map of STEP material name → G4Material*.
detectorName	Key to register the assembly under in G4OCCTAssemblyRegistry.
sensitiveNames	Volume name patterns to receive SD assignment (informational; SD assignment happens at ConstructSDandField time). Throws std::runtime_error on failure.
