DD4hep and Material Mapping
requested to merge 642-translation-of-material-material-mapping-proxies-from-dd4hep-to-acts into master
Closes #642 (closed)
This merge request synchronises the material mapping and DD4hep geometry building with the recently updated ActsExtension.
It introduces a xml2Acts translation for ProtoSurfaceMaterial in order to run the SurfaceMaterialMapper
It also fixes:
- translation of proto material through geometry building for boundary surfaces
- empty hit assignment errors (i.e. material rays that hit a surface but don't get material assigned) during material mapping. This required a a new
voidAverage()method to the accumulation classes that counts empty hits.
