2017 Cover Image: Mixing Bowl
Marra, Alessia; Nitti, Maurizio; Papas, Marios; Müller, Thomas; Gross, Markus; Jarosz, Wojciech; ovák, Jan (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017) -
Automatic Feature Selection for Denoising Volumetric Renderings
Zhang, Xianyao; Ott, Melvin; Manzi, Marco; Gross, Markus; Papas, Marios (The Eurographics Association and John Wiley & Sons Ltd., 2022)We propose a method for constructing feature sets that significantly improve the quality of neural denoisers for Monte Carlo renderings with volumetric content. Starting from a large set of hand-crafted features, we propose ... -
A computational appearance fabrication framework and derived applications
Papas, Marios (ETH Zurich, 2015)Traditionally, control over the appearance of objects in the real world was performed manually. Understanding how some physical property of an object would affect its appearance was achieved primarily through trial and ... -
Deep Compositional Denoising for High-quality Monte Carlo Rendering
Zhang, Xianyao; Manzi, Marco; Vogels, Thijs; Dahlberg, Henrik; Gross, Markus; Papas, Marios (The Eurographics Association and John Wiley & Sons Ltd., 2021)We propose a deep-learning method for automatically decomposing noisy Monte Carlo renderings into components that kernelpredicting denoisers can denoise more effectively. In our model, a neural decomposition module learns ... -
Deep Compositional Denoising on Frame Sequences
Zhang, Xianyao; Röthlin, Gerhard; Manzi, Marco; Gross, Markus; Papas, Marios (The Eurographics Association, 2023)Path tracing is the prevalent rendering algorithm in the animated movies and visual effects industry, thanks to its simplicity and ability to render physically plausible lighting effects. However, we must simulate millions ... -
NeRF-Tex: Neural Reflectance Field Textures
Baatz, Hendrik; Granskog, Jonathan; Papas, Marios; Rousselle, Fabrice; Novák, Jan (The Eurographics Association, 2021)We investigate the use of neural fields for modeling diverse mesoscale structures, such as fur, fabric, and grass. Instead of using classical graphics primitives to model the structure, we propose to employ a versatile ... -
Neural Denoising for Deep-Z Monte Carlo Renderings
Zhang, Xianyao; Röthlin, Gerhard; Zhu, Shilin; Aydin, Tunç Ozan; Salehi, Farnood; Gross, Markus; Papas, Marios (The Eurographics Association and John Wiley & Sons Ltd., 2024)We present a kernel-predicting neural denoising method for path-traced deep-Z images that facilitates their usage in animation and visual effects production. Deep-Z images provide enhanced flexibility during compositing ... -
Path Guiding Using Spatio‐Directional Mixture Models
Dodik, Ana; Papas, Marios; Öztireli, Cengiz; Müller, Thomas (© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2022)We propose a learning‐based method for light‐path construction in path tracing algorithms, which iteratively optimizes and samples from what we refer to as spatio‐directional Gaussian mixture models (SDMMs). In particular, ...
