Path-Traced Motion Blur using Motion Trees
(The Eurographics Association, 2020)
Motion Blur is an important effect of photo-realistic rendering. Distribution ray tracing can simulate motion blur very well by integrating light, both over the spatial and the temporal domain. However, increasing the ...
Visualização em Tempo Real de um Modelo Esparso de Mistura Paramétrica para Síntese da BTF
(The Eurographics Association, 2021)
As funções de textura bidirecionais (Bidirectional Texture Functions - BTF) permitem visualizações de alta qualidade de materiais reais, que exibem detalhes complexos na sua aparência, e que não podem ser fielmente ...
Improving Ray Tracing Performance with Variable Rate Shading
(The Eurographics Association, 2021)
Hardware-accelerated ray tracing has enabled ray traced reflections for real-time applications such as games. However, the number of traced rays during each frame must be kept low to achieve expected frame rates. Therefore, ...
Remote Volume Rendering with a Decoupled, Ray-Traced Display Phase
(The Eurographics Association, 2021)
We propose an image warping-based remote rendering technique for volumes that decouples the rendering and display phases. For that we build on prior work where we sample the volume on the client using ray casting and ...
Fast and Lightweight Path Guiding Algorithm on GPU
(The Eurographics Association, 2021)
We propose a simple, yet practical path guiding algorithm that runs on GPU. Path guiding renders photo-realistic images by simulating the iterative bounces of rays, which are sampled from the radiance distribution. The ...
Cloud-Assisted Hybrid Rendering for Thin-Client Games and VR Applications
(The Eurographics Association, 2021)
We introduce a novel distributed rendering approach to generate high-quality graphics in thin-client games and VR applications. Many mobile devices have limited computational power to achieve ray tracing in real-time. ...
EMCA: Explorer of Monte Carlo based Algorithms
(The Eurographics Association, 2021)
Debugging or analyzing the performance of global illumination algorithms is a challenging task due to the complex path-scene interaction and numerous places where errors and programming bugs can occur. We present a novel, ...
Stochastic Generation of (t, s) Sample Sequences
(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 ...
Controllable Caustic Animation Using Vector Fields
(The Eurographics Association, 2020)
In movie production, lighting is commonly used to redirect attention or to set the mood in a scene. The detailed editing of complex lighting phenomena, however, is as tedious as it is important, especially with dynamic ...
Conservative Ray Batching using Geometry Proxies
(The Eurographics Association, 2020)
We present a method for improving batched ray traversal as was presented by Pharr et al. [PKGH97]. We propose to use conservative proxy geometry to more accurately determine whether a ray has a possibility of hitting any ...
