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 ...
First Order Signed Distance Fields
(The Eurographics Association, 2020)
This paper investigates a first order generalization of signed distance fields. We show that we can improve accuracy and storage efficiency by incorporating the spatial derivatives of the signed distance function into the ...
Rayground: An Online Educational Tool for Ray Tracing
(The Eurographics Association, 2020)
In this paper, we present Rayground; an online, interactive education tool for richer in-class teaching and gradual self-study, which provides a convenient introduction into practical ray tracing through a standard ...
Photon Mapping Superluminal Particles
(The Eurographics Association, 2020)
One type of light source that remains largely unexplored in the field of light transport rendering is the light generated by superluminal particles, a phenomenon more commonly known as Cherenkov radiation [Cˇ37]. By ...
Monte Carlo Methods for Volumetric Light Transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
The wide adoption of path-tracing algorithms in high-end realistic rendering has stimulated many diverse research initiatives. In this paper we present a coherent survey of methods that utilize Monte Carlo integration for ...
A Survey on Gradient-Domain Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Monte Carlo methods for physically-based light transport simulation are broadly adopted in the feature film production, animation and visual effects industries. These methods, however, often result in noisy images and have ...
Analysis of Sample Correlations for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Modern physically based rendering techniques critically depend on approximating integrals of high dimensional functions representing radiant light energy. Monte Carlo based integrators are the choice for complex scenes and ...
A Survey on Bounding Volume Hierarchies for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Ray tracing is an inherent part of photorealistic image synthesis algorithms. The problem of ray tracing is to find the nearest intersection with a given ray and scene. Although this geometric operation is relatively simple, ...
Accelerating Sphere Tracing
(The Eurographics Association, 2018)
This paper presents two performance improvements on sphere tracing. First, a sphere tracing variant designed to take optimal step sizes near planar surfaces is proposed. We demonstrate how relaxation is used to make this ...
