Sarah Invernizzi Showreel MSc 2012-13
Showreel by MSC student Sarah Invernizzi, showcasing various projects undertaken whilst studying at the NCCA at Bournemouth University.
‘On Physically Based Hair Rendering’ investigates two importance sampled hair reflectance models, ‘ISHair: Importance Sampling for Hair Reflection’ (Ou et al., 2012), and ‘Importance Sampling of Reflection from Hair Fibers’ (Hery and Ramamoorthi, 2012). The former importance samples only the Marschner reflection lobe, and the latter importance samples the three lobes commonly associated with light scattering from hair: the primary and secondary reflections, and forward scattering. Both shaders are implemented in RSL and images are rendered using the physically plausible pipeline in RenderMan Pro Server 18.0. Hair self-shadowing and anti-aliasing are also investigated. The best shadowing results are achieved with deep area shadow maps and attempts to reduce noise from a sequence of moving images show promising results.
