Selective BRDFs for High Fidelity Rendering

Tim Bradley, Kurt Debattista, Thomas Bashford-Rogers, Carlo Harvey, Stratos Doukakis & Alan Chalmers
High fidelity rendering systems rely on accurate material representations to produce a realistic visual appearance. However, these accurate models can be slow to evaluate. This work presents an approach for approximating these high accuracy reflectance models with faster, less complicated functions in regions of an image which possess low visual importance. A subjective rating experiment was conducted in which thirty participants were asked to assess the similarity of scenes rendered with low quality reflectance models,...
