DD4hep serves as a generic detector description toolkit recommended for offline software development in next-generation high-energy physics(HEP)***,Filmbox(FBX)stands out as a widely used 3D modeling file format within the 3D software *** this paper,we introduce a novel method that can automatically convert complex HEP detector geometries from DD4hep description into 3D models in the FBX *** feasibility of this method was dem-onstrated by its application to the DD4hep description of the Compact Linear Collider detector and several sub-detectors of the super Tau-Charm facility and circular electron-positron collider *** automatic DD4hep–FBX detector conversion interface provides convenience for further development of applications,such as detector design,simulation,visualization,data monitoring,and outreach,in HEP experiments.

A method for detector description exchange among ROOT GEANT4 and GEANT3

引用

Chinese Physics C 2008年第7期32卷 572-575页

作者：尤郑昀梁羽铁冒亚军 School of Physics Peking UniversityBeijing 100871China Los Alamos National LaboratoryLos AlamosNew Mexico 87545USA School of Physics Peking UniversityBeijing 100871China School of Physics Peking UniversityBelling 100871China

GEANT3 and GEANT4 are the detector simulation software programs that are widely used in most nuclear and particle physics experiments. ROOT is a program for framework, data analysis, online and offiine software. detector description is an important function in all these programs. Due to different detector construction methods and respective detector data representative, it is difficult to exchange the detector data among them. A new method based on GDML is developed to automatically convert the detector data among ROOT, GEANT4 and GEANT3. Any existing detector geometry in one program can be mapped to the geometry in the other two programs. In the software development of an experiment, different applications can share and reuse the same detector description. The application of this method in the PHENIX experiment upgrade and PHENIX Forward Vertex Silicon detector design is introduced.

＜正＞Offline Software such as Simulation, Reconstruction, Analysis, and Visualisation are all in need of a detector description. These applications have several common but also many specific requirements for the detector description in order to build up their internal representations. To achieve this in a consistent and coherent manner a common source of information, the detector description database, will be consulted by each of the applications. The role and suitability of XML in the design of the detector description database in the scope of the CMS detector at the LHC is discussed. Different aspects such as data modelling capabilities of XML, tool support, integration to C++ representations of data models are treated and recent results of prototype implementations are presented.
