    • NeLF: Neural Light-transport Field for Portrait View Synthesis and Relighting 

      Sun, Tiancheng; Lin, Kai-En; Bi, Sai; Xu, Zexiang; Ramamoorthi, Ravi (The Eurographics Association, 2021)
      Human portraits exhibit various appearances when observed from different views under different lighting conditions. We can easily imagine how the face will look like in another setup, but computer algorithms still fail on ...

    • MatMorpher: A Morphing Operator for SVBRDFs 

      Gauthier, Alban; Thiery, Jean-Marc; Boubekeur, Tamy (The Eurographics Association, 2021)
      We present a novel morphing operator for spatially-varying bidirectional reflectance distribution functions. Our operator takes as input digital materials modeled using a set of 2D texture maps which control the typical ...

    • Practical Ply-Based Appearance Modeling for Knitted Fabrics 

      Montazeri, Zahra; Gammelmark, Søren; Jensen, Henrik Wann; Zhao, Shuang (The Eurographics Association, 2021)
      Abstract Modeling the geometry and the appearance of knitted fabrics has been challenging due to their complex geometries and interactions with light. Previous surface-based models have difficulties capturing fine-grained ...

    • Firefly Removal in Monte Carlo Rendering with Adaptive Median of meaNs 

      Buisine, Jérôme; Delepoulle, Samuel; Renaud, Christophe (The Eurographics Association, 2021)
      Estimating the rendering equation using Monte Carlo methods produces photorealistic images by evaluating a large number of samples of the rendering equation per pixel. The final value for each pixel is then calculated as ...

    • Fast Analytic Soft Shadows from Area Lights 

      Kt, Aakash; Sakurikar, Parikshit; Narayanan, P. J. (The Eurographics Association, 2021)
      In this paper, we present the first method to analytically compute shading and soft shadows for physically based BRDFs from arbitrary area lights.We observe that for a given shading point, shadowed radiance can be computed ...

    • Appearance-Driven Automatic 3D Model Simplification 

      Hasselgren, Jon; Munkberg, Jacob; Lehtinen, Jaakko; Aittala, Miika; Laine, Samuli (The Eurographics Association, 2021)
      We present a suite of techniques for jointly optimizing triangle meshes and shading models to match the appearance of reference scenes. This capability has a number of uses, including appearance-preserving simplification ...

    • Fast Polygonal Splatting using Directional Kernel Difference 

      Moroto, Yuji; Hachisuka, Toshiya; Umetani, Nobuyuki (The Eurographics Association, 2021)
      Depth-of-field (DoF) filtering is an important image-processing task for producing blurred images similar to those obtained with a large aperture camera lens. DoF filtering applies an image convolution with a spatially ...

    • Material and Lighting Reconstruction for Complex Indoor Scenes with Texture-space Differentiable Rendering 

      Nimier-David, Merlin; Dong, Zhao; Jakob, Wenzel; Kaplanyan, Anton (The Eurographics Association, 2021)
      Modern geometric reconstruction techniques achieve impressive levels of accuracy in indoor environments. However, such captured data typically keeps lighting and materials entangled. It is then impossible to manipulate the ...

    • Semantic-Aware Generative Approach for Image Inpainting 

      Chanda, Deepankar; Kalantari, Nima Khademi (The Eurographics Association, 2021)
      We propose a semantic-aware generative method for image inpainting. Specifically, we divide the inpainting process into two tasks; estimating the semantic information inside the masked areas and inpainting these regions ...

    • Practical Product Sampling for Single Scattering in Media 

      Villeneuve, Keven; Gruson, Adrien; Georgiev, Iliyan; Nowrouzezahrai, Derek (The Eurographics Association, 2021)
      Efficient Monte-Carlo estimation of volumetric single scattering remains challenging due to various sources of variance, including transmittance, phase-function anisotropy, geometric cosine foreshortening, and squared-distance ...

    • Importance Sampling of Glittering BSDFs based on Finite Mixture Distributions 

      Chermain, Xavier; Sauvage, Basile; Dischler, Jean-Michel; Dachsbacher, Carsten (The Eurographics Association, 2021)
      We propose an importance sampling scheme for the procedural glittering BSDF of Chermain et al. [CSDD20]. Glittering BSDFs have multi-lobe visible normal distribution functions (VNDFs) which are difficult to sample. They ...

    • Sampling Clear Sky Models using Truncated Gaussian Mixtures 

      Vitsas, Nick; Vardis, Konstantinos; Papaioannou, Georgios (The Eurographics Association, 2021)
      Parametric clear sky models are often represented by simple analytic expressions that can efficiently generate plausible, natural radiance maps of the sky, taking into account expensive and hard to simulate atmospheric ...

    • Stochastic Generation of (t, s) Sample Sequences 

      Helmer, Andrew; Christensen, Per; Kensler, Andrew (The Eurographics Association, 2021)
      We introduce a novel method to generate sample sequences that are progressively stratified both in high dimensions and in lower-dimensional projections. Our method comes from a new observation that Owen-scrambled quasi-Monte ...

    • Zero-variance Transmittance Estimation 

      d'Eon, Eugene; Novák, Jan (The Eurographics Association, 2021)
      We apply zero-variance theory to the Volterra integral formulation of volumetric transmittance.We solve for the guided sampling decisions in this framework that produce zero-variance ratio tracking and next-flight ratio ...
