      It is well known that cubic texture filtering can be efficiently implemented on the GPU by using a method published by Sigg and Hadwiger [SH05], which simplifies the evaluation to a linear combination of linear texture ...
    • Approximate Program Smoothing Using Mean-Variance Statistics, with Application to Procedural Shader Bandlimiting 

      Yang, Yuting; Barnes, Connelly (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We introduce a general method to approximate the convolution of a program with a Gaussian kernel. This results in the program being smoothed. Our compiler framework models intermediate values in the program as random ...
    • Procedural Cloudscapes 

      Webanck, Antoine; Cortial, Yann; Guérin, Eric; Galin, Eric (The Eurographics Association and John Wiley & Sons Ltd., 2018)

    • Procedural Modeling of a Building from a Single Image 

      Nishida, Gen; Bousseau, Adrien; Aliaga, Daniel G. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Creating a virtual city is demanded for computer games, movies, and urban planning, but it takes a lot of time to create numerous 3D building models. Procedural modeling has become popular in recent years to overcome this ...
    • Example-based Authoring of Procedural Modeling Programs with Structural and Continuous Variability 

      Ritchie, Daniel; Jobalia, Sarah; Thomas, Anna (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Procedural models are a powerful tool for quickly creating a variety of computer graphics content. However, authoring them is challenging, requiring both programming and artistic expertise. In this paper, we present a ...
    • Deep Joint Design of Color Filter Arrays and Demosaicing 

      Henz, Bernardo; Gastal, Eduardo S. L.; Oliveira, Manuel M. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We present a convolutional neural network architecture for performing joint design of color filter array (CFA) patterns and demosaicing. Our generic model allows the training of CFAs of arbitrary sizes, optimizing each ...
    • Single-image Tomography: 3D Volumes from 2D Cranial X-Rays 

      Henzler, Philipp; Rasche, Volker; Ropinski, Timo; Ritschel, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      As many different 3D volumes could produce the same 2D x-ray image, inverting this process is challenging. We show that recent deep learning-based convolutional neural networks can solve this task. As the main challenge ...
    • Practical Radiometric Compensation for Projection Display on Textured Surfaces using a Multidimensional Model 

      Li, Yuqi; Majumder, Aditi; Gopi, Meenakshisundaram; Wang, Chong; Zhao, Jieyu (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Radiometric compensation methods remove the effect of the underlying spatially varying surface reflectance of the texture when projecting on textured surfaces. All prior work sample the surface reflectance dependent ...
    • Hair Modeling and Simulation by Style 

      Jung, Seunghwan; Lee, Sung-Hee (The Eurographics Association and John Wiley & Sons Ltd., 2018)
