Point-Pattern Synthesis using Gabor and Random Filters
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Point pattern synthesis requires capturing both local and non-local correlations from a given exemplar. Recent works employ deep hierarchical representations from VGG-19 [SZ15] convolutional network to capture the features ... -
pOp: Parameter Optimization of Differentiable Vector Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Procedural materials are extensively used in computer graphics, since they provide editable, resolution-independent representation of textures. However, tuning the parameters of procedural generators to achieve a desired ... -
Recolorable Posterization of Volumetric Radiance Fields Using Visibility-Weighted Palette Extraction
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Volumetric radiance fields have recently gained significant attention as promising representations of photorealistic scene reconstruction. However, the non-photorealistic rendering of such a representation has barely been ... -
Deep Flow Rendering: View Synthesis via Layer-aware Reflection Flow
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Novel view synthesis (NVS) generates images from unseen viewpoints based on a set of input images. It is a challenge because of inaccurate lighting optimization and geometry inference. Although current neural rendering ... -
Physics-Based Inverse Rendering using Combined Implicit and Explicit Geometries
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Mathematically representing the shape of an object is a key ingredient for solving inverse rendering problems. Explicit representations like meshes are efficient to render in a differentiable fashion but have difficulties ... -
Controlling Material Appearance by Examples
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Despite the ubiquitous use of materials maps in modern rendering pipelines, their editing and control remains a challenge. In this paper, we present an example-based material control method to augment input material maps ... -
Microsurface Transformations
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We derive a general result in microfacet theory: given an arbitrary microsurface defined via standard microfacet statistics, we show how to construct the statistics of its linearly transformed counterparts. A common use ... -
A Position-Free Path Integral for Homogeneous Slabs and Multiple Scattering on Smith Microfacets
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We consider the problem of multiple scattering on Smith microfacets. This problem is equivalent to computing volumetric light transport in a homogeneous slab. Although the symmetry of the slab allows for significant ... -
Automatic Feature Selection for Denoising Volumetric Renderings
(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 Microfacet-based Hair Scattering Model
(The Eurographics Association and John Wiley & Sons Ltd., 2022)The development of scattering models and rendering algorithms for human hair remains an important area of research in computer graphics. Virtually all available models for scattering off hair or fur fibers are based on ... -
A Bidirectional Formulation for Walk on Spheres
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Numerically solving partial differential equations (PDEs) is central to many applications in computer graphics and scientific modeling. Conventional methods for solving PDEs often need to discretize the space first, making ... -
Single-pass Stratified Importance Resampling
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Resampling is the process of selecting from a set of candidate samples to achieve a distribution (approximately) proportional to a desired target. Recent work has revisited its application to Monte Carlo integration, ... -
Temporally Sliced Photon Primitives for Time-of-flight Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We derive a class of new Monte Carlo estimators for volumetric time-of-flight rendering, generalizing prior work on transient photon points and beams. Conceptually, our method starts with any steady-state photon primitive ... -
Once-more Scattered Next Event Estimation for Volume Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We present a Monte Carlo path tracing technique to sample extended next event estimation contributions in participating media: we consider one additional scattering vertex on the way to the next event, accounting for focused ... -
Path Guiding with Vertex Triplet Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Good importance sampling strategies are decisive for the quality and robustness of photorealistic image synthesis with Monte Carlo integration. Path guiding approaches use transport paths sampled by an existing base sampler ... -

Topological Simplification of Nested Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We present a method for removing unwanted topological features (e.g., islands, handles, cavities) from a sequence of shapes where each shape is nested in the next. Such sequences can be found in nature, such as a multi-layered ... -
Fabricable Multi-Scale Wang Tiles
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Wang tiles, also known as Wang dominoes, are a jigsaw puzzle system with matching edges. Due to their compactness and expressiveness in representing variations, they have become a popular tool in the procedural synthesis ... -
Hex Me If You Can
(The Eurographics Association and John Wiley & Sons Ltd., 2022)HexMe consists of 189 tetrahedral meshes with tagged features and a workflow to generate them. The primary purpose of HexMe meshes is to enable consistent and practically meaningful evaluation of hexahedral meshing algorithms ... -
Constructing L∞ Voronoi Diagrams in 2D and 3D
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Voronoi diagrams and their computation are well known in the Euclidean L2 space. They are easy to sample and render in generalized Lp spaces but nontrivial to construct geometrically. Especially the limit of this norm with ...
