16 | This section describes just a few of the more commonly used |
---|
17 | visualization commands. For the complete list of commands and |
---|
18 | options, see the |

24 | For simplicity, this section assumes that the Geant4 executable |
---|
25 | was compiled incorporating the DAWNFILE and the OpenGL-Xlib |

26 | drivers. For details on creating an executable for visualization |

37 | <para> |
---|
38 | In using the visualization commands, it is useful to know the |
---|
39 | concept of "scene", "scene handler", and "viewer". A "scene" is a |
---|
40 | set of visualizable raw 3D data. A "scene handler" is a |
---|
41 | graphics-data modeler, which processes raw data in a scene for |
---|
42 | later visualization. And a "viewer" generates images based on data |
---|
43 | processed by a scene handler. Roughly speaking, a set of a scene |
---|
44 | handler and a viewer corresponds to a visualization driver. |
---|
45 | </para> |
---|
46 | |
---|
47 | <para> |
---|
48 | The steps of performing Geant4 visualization are explained |
---|
49 | below, though some of these steps may be done for you so that in |
---|
50 | practice you may use as few as just two commands (such as /vis/open |
---|
51 | OGLIX plus /vis/drawVolume) The seven steps of visualization are: |
---|
52 | |
---|
53 | <itemizedlist spacing="compact"> |

79 | These seven steps can be controlled explicitly to create |
---|
80 | multiple scenes and multiple viewers, each with its own set of |
---|
81 | parameters, with easy switching from one scene to another. But for |
---|
82 | the most common case of just having one scene and one viewer, many |
---|
83 | steps are handled implicitly for you. |

770 | How to save a visualized views to PostScript files |

771 | </title> |

772 | |
---|
773 | <para> |
---|
774 | Most of the visualization drivers offer ways to save visualized |
---|
775 | views to PostScript files (or Encapsulated PostScript (EPS) files) |

776 | by themselves. |

780 | The DAWNFILE driver, which co-works with Fukui Renderer DAWN, |
---|
781 | generates "vectorized" PostScript data with "analytical |
---|
782 | hidden-line/surface removal", and so it is well suited for |
---|
783 | technical high-quality outputs for presentation, documentation, and |
---|
784 | debugging geometry. In the default setting of the DAWNFILE drivers, |
---|
785 | EPS files named "<literal>g4_00.eps, g4_01.eps, g4_02.eps</literal>,..." are |
---|
786 | automatically generated in the current directory each time when |
---|
787 | visualization is performed, and then a PostScript viewer |
---|
788 | "<literal>gv</literal>"is automatically invoked to visualize the generated |
---|
789 | EPS files. |
---|
790 | </para> |
---|
791 | |
---|
792 | <para> |
---|
793 | For large data sets, it may take time to generate the vectorized |
---|
794 | PostScript data. In such a case, visualize the 3D scene with a |
---|
795 | faster visualization driver beforehand for previewing, and then use |
---|
796 | the DAWNFILE drivers. For example, the following visualizes the |
---|
797 | whole detector with the OpenGL-Xlib driver (immediate mode) first, |
---|
798 | and then with the DAWNFILE driver to generate an EPS file |
---|
799 | <literal>g4_XX.eps</literal> to save the visualized view: |

862 | "Culling" means to skip visualizing parts of a 3D scene. Culling is |

863 | useful for avoiding complexity of visualized views, keeping |

997 | "Sectioning" means to make a thin slice of a 3D scene around a |

998 | given plane. At present, this function is supported by the OpenGL |
---|
999 | drivers. The sectioning is realized by setting a sectioning plane |
---|
1000 | before performing visualization. The sectioning plane can be set by |
---|
1001 | the command, |
