    • Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces 

      Mehta, Soham Uday; Ramamoorthi, Ravi; Meyer, Mark; Hery, Christophe (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...

    • Intrinsic Images by Clustering 

      Garces, Elena; Munoz, Adolfo; Lopez-Moreno, Jorge; Gutierrez, Diego (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Decomposing an input image into its intrinsic shading and reflectance components is a long-standing ill-posed problem. We present a novel algorithm that requires no user strokes and works on a single image. Based on simple ...

    • Per-Vertex Defocus Blur for Stochastic Rasterization 

      Munkberg, Jacob; Toth, Robert; Akenine-Möller, Tomas (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to ...

    • A Stylized Approach for Pencil Drawing from Photographs 

      Yang, Heekyung; Kwon, Yunmi; Min, Kyungha (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a stylized scheme that produces pencil drawings in a range of styles from an image. To produce controllable pencil drawing effects and remedy the problems of existing convolution-based schemes, we develop a swing ...
