Efficient Ray Tracing Through Aspheric Lenses and Imperfect Bokeh Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present an efficient ray-tracing technique to render bokeh effects produced by parametric aspheric lenses. Contrary to conventional spherical lenses, aspheric lenses do generally not permit a simple closed-form solution ...
Forward Light Cuts: A Scalable Approach to Real-Time Global Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present Forward Light Cuts, a novel approach to real-time global illumination using forward rendering techniques. We focus on unshadowed diffuse interactions for the first indirect light bounce in the context of large ...
A Phenomenological Model for Throughfall Rendering in Real-time
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper aims at rendering interactive visual effects inherent to complex interactions between trees and rain in real-time in order to increase the realism of natural rainy scenes. Such a complex phenomenon involves a ...
Product Importance Sampling for Light Transport Path Guiding
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
The efficiency of Monte Carlo algorithms for light transport simulation is directly related to their ability to importance-sample the product of the illumination and reflectance in the rendering equation. Since the optimal ...
Perceptually Motivated BRDF Comparison using Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Surface reflectance of real-world materials is now widely represented by the bidirectional reflectance distribution function (BRDF) and also by spatially varying representations such as SVBRDF and the bidirectional texture ...
Retailoring Box Splines to Lattices for Highly Isotropic Volume Representations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
3D box splines are defined by convolving a 1D box function with itself along different directions. In volume visualization, box splines are mainly used as reconstruction kernels that are easy to adapt to various sampling ...
Geometry and Attribute Compression for Voxel Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Voxel-based approaches are today's standard to encode volume data. Recently, directed acyclic graphs (DAGs) were successfully used for compressing sparse voxel scenes as well, but they are restricted to a single bit of ...
Single Image Weathering via Exemplar Propagation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper presents an efficient approach for generating weathering effects with detailed appearance variations in a single image. Previous approaches merely change chroma or reflectance of weathered objects, which is not ...
Sparse Representation of Terrains for Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In this paper, we present a simple and efficient method to represent terrains as elevation functions built from linear combinations of landform features (atoms). These features can be extracted either from real world ...
General Projective Maps for Multidimensional Data Projection
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
To project high-dimensional data to a 2D domain, there are two well-established classes of approaches: RadViz and Star Coordinates. Both are well-explored in terms of accuracy, completeness, distortions, and interaction ...
