Transparent Visualization of Highlighting Edges for Radiation Simulator with Complex Structure

Abstract

The high-energy particle detector simulator “Geant4” has excellent functions of visualization. Since the Geant4 visualizer should treat detectors with complex 3D structures, it is important to visualize polygon edges. Besides, transparent see-through visualization is also very effective. In this study, we develop a new Geant4 visualizer, which supports high-quality transparent rendering and highlighting polygon edges. We use the particle-based surface rendering for transparent visualization of a polygon mesh. Besides, we use the particle-based line rendering, which we propose in this paper, for highlighting polygon edges. Polygon meshes and polygon edges are converted into point data independently and then merged to make unified visualization.
