This thesis is an investigation into the use of Volume Graphics techniques for the purpose of forensic facial reconstruction. The thesis also examines the rapid creation of a light volume for the accurate rendering of light within a scene. The main achievements of this thesis are: an examination of forensic facial reconstruction techniques, both manual and automatic; identification of weaknesses of these methods and an improved automatic method using a volume graphics approach; a general introduction to the rapidly evolving field of volume graphics; the introduction of a technique for calculating fast, accurate measurements of light intensities inside a volume dataset. This work has demonstrated that it is now feasible to use a computer to reconstruct the face of an unknown person given his/her skull without allowing artistic interpretation. It has also demonstrated that it is computationally feasible to calculate a “light volume” to store light intensities at voxel points within a volume, thus allowing for much faster recreation of shadowing effects e.g. during rendering. Part of this research was presented by the candidate at the 19<sup>th</sup> Eurographics UK conference at the University College, London, 2001.
