void genf::GFGeoMatManager::initTrack ( const double &  posx, const double &  posy, const double &  posz, const double &  dirx, const double &  diry, const double &  dirz  )

virtual

Initializes the track.

}

double genf::GFGeoMatManager::stepOrNextBoundary ( const double &  maxDist )

virtual

Makes a step, limited to next material boundary.

Tries to make a step with length maxDist along the track. If there is a material boundary, the step is made to that boundary and the distance to that boundary is returned. Otherwise the step is made with maxDist.

Implements genf::GFAbsGeoMatManager.
