Fast Procedural Noise By Monte Carlo Sampling
(The Eurographics Association, 2023)Procedural noise functions are widely used in computer graphics as a way to add texture detail to surfaces and volumes. Many noise functions are based on weighted sums that can be expressed in terms of random variables, ... -
Floaters No More: Radiance Field Gradient Scaling for Improved Near-Camera Training
(The Eurographics Association, 2023)NeRF acquisition typically requires careful choice of near planes for the different cameras or suffers from background collapse, creating floating artifacts on the edges of the captured scene. The key insight of this work ... -
FloralSurf: Space-Filling Geodesic Ornaments
(The Eurographics Association, 2023)We propose a method to generate floral patterns on manifolds without relying on parametrizations. Taking inspiration from the literature on procedural space-filling vegetation, these patterns are made of non-intersecting ... -
Gaze-Contingent Perceptual Level of Detail Prediction
(The Eurographics Association, 2023)New virtual reality headsets and wide field-of-view displays rely on foveated rendering techniques that lower the rendering quality for peripheral vision to increase performance without a perceptible quality loss. While ... -
Learning Projective Shadow Textures for Neural Rendering of Human Cast Shadows from Silhouettes
(The Eurographics Association, 2023)This contribution introduces a two-step, novel neural rendering framework to learn the transformation from a 2D human silhouette mask to the corresponding cast shadows on background scene geometries. In the first step, the ... -
Mean Value Caching for Walk on Spheres
(The Eurographics Association, 2023)Walk on Spheres (WoS) is a grid-free Monte Carlo method for numerically estimating solutions for elliptical partial differential equations (PDE) such as the Laplace and Poisson PDEs. While WoS is efficient for computing a ... -
A Microfacet Model for Specular Fluorescent Surfaces and Fluorescent Volume Rendering using Quantum Dots
(The Eurographics Association, 2023)Fluorescent appearance of materials results from a complex light-material interaction phenomenon. The modeling of fluorescent material for rendering has only been addressed through measurement or for simple diffuse ... -
pEt: Direct Manipulation of Differentiable Vector Patterns
(The Eurographics Association, 2023)Procedural assets are used in computer graphics applications since variations can be obtained by changing the parameters of the procedural programs. As the number of parameters increases, editing becomes cumbersome as users ... -
Practical Temporal and Stereoscopic Filtering for Real-time Ray Tracing
(The Eurographics Association, 2023)We present a practical method for temporal and stereoscopic filtering that generates stereo-consistent rendering. Existing methods for stereoscopic rendering often reuse samples from one eye for the other or do averaging ... -
SparseBTF: Sparse Representation Learning for Bidirectional Texture Functions
(The Eurographics Association, 2023)We propose a novel dictionary-based representation learning model for Bidirectional Texture Functions (BTFs) aiming at compact storage, real-time rendering performance, and high image quality. Our model is trained once, ...
