Photon Splatting Using a View-Sample Cluster Hierarchy
(The Eurographics Association, 2016)
Splatting photons onto primary view samples, rather than gathering from a photon acceleration structure, can be a more efficient approach to evaluating the photon-density estimate in interactive applications, where the ...
High-Performance Rendering of Realistic Cumulus Clouds Using Pre-computed Lighting
(The Eurographics Association, 2014)
We present a new method for rendering realistic cumulus clouds in real time. The clouds in our approach consist of randomly rotated and scaled copies of a single reference particle. During the pre-processing, we pre-compute ...
Layered Reflective Shadow Maps for Voxel-based Indirect Illumination
(The Eurographics Association, 2014)
We introduce a novel voxel-based algorithm that interactively simulates both diffuse and glossy single-bounce indirect illumination. Our algorithm generates high quality images similar to the reference solution while using ...
Filtering Distributions of Normals for Shading Antialiasing
(The Eurographics Association, 2016)
High-frequency illumination effects, such as highly glossy highlights on curved surfaces, are challenging to render in a stable manner. Such features can be much smaller than the area of a pixel and carry a high amount of ...
Interactive Position-dependent Customization of Transfer Function Classification Parameters in Volume Rendering
(The Eurographics Association, 2015)
In direct volume rendering (DVR) and related techniques a basic operation is the classification of data values by mapping (mostly scalar) intensities to color values using a transfer function. However, in some cases this ...
Using Flash Photography and Image-Based Rendering to Document Cultural Heritage Artifacts
(The Eurographics Association, 2016)
A novel image-based rendering system is proposed for documenting cultural heritage artifacts. The system utilizes backscattering photography to acquire the initial pictures and derives estimates for the object's diffuse ...
Weathering of Urban Scenes: Challenges and Possible Solutions
(The Eurographics Association, 2016)
In this paper, we propose to discuss on one of the main challenges in realistic rendering of urban scenes: changes in appearance over time within a urban context. After studying the previous work on weathering techniques, ...
Practical Experiences with Using Autocollimator for Surface Reflectance Measurement
(The Eurographics Association, 2016)
We present our experiences with using an autocollimator to set up the surface reflectance measurement for both BRDF and BTF. Assuming the measured material appearance is put on a locally flat surface, the autocollimator ...
Color Restoration of Scanned Archaeological Artifacts with Repetitive Patterns
(The Eurographics Association, 2016)
Our work addresses the problem of virtually restoring archaeological artifacts. Virtual restoration is the process of creating a noise-free model of a degraded object, to visualize its original appearance. Our work focuses ...
Pre-convolved Radiance Caching
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both ...
