    • Efficient Ray Tracing Through Aspheric Lenses and Imperfect Bokeh Synthesis 

      Joo, Hyuntae; Kwon, Soonhyeon; Lee, Sangmin; Eisemann, Elmar; Lee, Sungkil (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present an efficient ray-tracing technique to render bokeh effects produced by parametric aspheric lenses. Contrary to conventional spherical lenses, aspheric lenses do generally not permit a simple closed-form solution ...
