Study on Detector Geometry Transformation and Visualization in Unity

Abstract In High Energy Physics (HEP) experiments, it is useful for physics analysis and outreach if the event display software can provide sophisticated visualization effects. Unity professional that provides 3D modeling animation production. GDML format files are commonly used detector descriptions in HEP experiments. this work, we present a method automating import of to engine through geometric transformation. With conversion file format, complicated description be imported directly into using an FBX file. This was applied BESIII experiments achieve automated geometry build models engine.
