Sky Based Light Metering for High Dynamic Range Images
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Image calibration requires both linearization of pixel values and scaling so that values in the image correspond to real-world luminances. In this paper we focus on the latter and rather than rely on camera characterization, ...
Real-Time Symmetry-Preserving Deformation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
In this paper, we address the problem of structure-aware shape deformation: We specifically consider deformations that preserve symmetries of the shape being edited. While this is an elegant approach for obtaining plausible ...
Perceptually-motivated Stereoscopic Film Grain
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Independent management of film grain in each view of a stereoscopic video can lead to visual discomfort. The existing alternative is to project the grain onto the scene geometry. Such grain, however, looks unnatural, changes ...
Deep Screen Space for Indirect Lighting of Volumes
(The Eurographics Association, 2014)
We present a method to render approximate indirect light transport from surfaces to volumes which is fully dynamic with respect to geometry, the medium and the main light sources, running at interactive speed. This is ...
Pattern Search in Flows based on Similarity of Stream Line Segments
(The Eurographics Association, 2014)
We propose a method that allows users to define flow features in form of patterns represented as sparse sets of stream line segments. Our approach finds ''similar'' occurrences in the same or other time steps. Related ...
Progressive Spectral Ray Differentials
(The Eurographics Association, 2014)
Light travelling though refractive objects can lead to beautiful colourful illumination patterns resulting from dispersion on the object interfaces. While this can be accurately simulated by stochastic Monte-Carlo methods, ...
Interactive Motion Mapping for Real-time Character Control
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Abstract It is now possible to capture the 3D motion of the human body on consumer hardware and to puppet in real time skeleton-based virtual characters. However, many characters do not have humanoid skeletons. Characters ...
Real-time Reflective and Refractive Novel-view Synthesis
(The Eurographics Association, 2014)
We extend novel-view image synthesis from the common diffuse and opaque image formation model to the reflective and refractive case. Our approach uses a ray tree of RGBZ images, where each node contains one RGB light path ...
Manipulating Refractive and Reflective Binocular Disparity
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Presenting stereoscopic content on 3D displays is a challenging task, usually requiring manual adjustments. A number of techniques have been developed to aid this process, but they account for binocular disparity of surfaces ...
Spectral Ray Differentials
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Light refracted by a dispersive interface leads to beautifully colored patterns that can be rendered faithfully with spectral Monte-Carlo methods. Regrettably, results often suffer from chromatic noise or banding, requiring ...
