0002 Extension plugins for reconstruction
0003 ====================================
0004
0005 The need of the various reconstruction programs used to create e.g. tracks
0006 from hits may differ significantly and may require different helper data
0007 to perform the required functions.
0008 In general the reconstruction is supported by the detector elements with
0009 helper objects (in dd4hep speak these are called Views). Some default views
0010 are provided by this package for some of the detector constructors of the
0011 "default subdetector palette".
0012 We first show how to invoke these plugins in order to attach the required
0013 extension object and then briefly discuss the plugin palette and its
0014 applicability to the various detector constructor types.

0016 Invokation of Extension Plugins
0017 ===============================
0018
0019 To add DetElement extensions simply add the corresponding plugin.
0020 This could be performed either by loading a seperate lccdd XML from the
0021 command line/python interface or adding the corrsponding structures directly
0022 into the primary lccdd file:
0023
0024 <lccdd ..../>
0025 ....
0026 <plugins>
0027 <plugin name="....plugin name.....">
0028 <argument value="......subdetector name......"/>
0029 ....
0030 <argument value="......another subdetector name......"/>
0031 </plugin>
0032 ....
0033 </plugins>
0034 ....
0035 </lccdd>
