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.展开更多
