In neutrino physics, large-volume liquid scintillator detectors are important and commonly used tools. They use the emitted isotropic scintillation light to collect information on the detected event. However, due to spatial and temporal projection of the emitted light information---from a spatially extended region in the detector onto discrete photosensors---reconstruction of the event's topology is demanding.
A new reconstruction method based on the propagation time of the detected photons is in development. This method produces 3D volume data which reflect the event's geometry and topology. Using Monte-Carlo simulations of single tracks in the LENA detector, the first steps towards automatic extraction of parameters as input for subsequent analyses are presented.
