DFR: Differentiable Function Rendering for Learning 3D Generation from Images
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Learning-based 3D generation is a popular research field in computer graphics. Recently, some works adapted implicit function defined by a neural network to represent 3D objects and have become the current state-of-the-art. ...
Unsupervised Image Reconstruction for Gradient-Domain Volumetric Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Gradient-domain rendering can highly improve the convergence of light transport simulation using the smoothness in image space. These methods generate image gradients and solve an image reconstruction problem with rendered ...
Spherical Gaussian Light-field Textures for Fast Precomputed Global Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We describe a method to use Spherical Gaussians with free directions and arbitrary sharpness and amplitude to approximate the precomputed local light field for any point on a surface in a scene. This allows for a high-quality ...
Spectral Mollification for Bidirectional Fluorescence
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Fluorescent materials can shift energy between wavelengths, thereby creating bright and saturated colors both in natural and artificial materials. However, rendering fluorescence for continuous wavelengths or combined with ...
Neural Denoising with Layer Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We propose a novel approach for denoising Monte Carlo path traced images, which uses data from individual samples rather than relying on pixel aggregates. Samples are partitioned into layers, which are filtered separately, ...
Adaptive Matrix Completion for Fast Visibility Computations with Many Lights Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Several fast global illumination algorithms rely on the Virtual Point Lights framework. This framework separates illumination into two steps: first, propagate radiance in the scene and store it in virtual lights, then ...
A Scalable and Production Ready Sky and Atmosphere Rendering Technique
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We present a physically based method to render the atmosphere of a planet from ground to space views. Our method is cheap to compute and, as compared to previous successful methods, does not require any high dimensional ...
Photorealistic Material Editing Through Direct Image Manipulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Creating photorealistic materials for light transport algorithms requires carefully fine-tuning a set of material properties to achieve a desired artistic effect. This is typically a lengthy process that involves a trained ...
Next Event Estimation++: Visibility Mapping for Efficient Light Transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Monte-Carlo rendering requires determining the visibility between scene points as the most common and compute intense operation to establish paths between camera and light source. Unfortunately, many tests reveal occlusions ...
Two-stage Resampling for Bidirectional Path Tracing with Multiple Light Sub-paths
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Recent advances in bidirectional path tracing (BPT) reveal that the use of multiple light sub-paths and the resampling of a small number of these can improve the efficiency of BPT. By increasing the number of pre-sampled ...
