Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...
Exploiting the PANORAMA Representation for Convolutional Neural Network Classification and Retrieval
(The Eurographics Association, 2017)
A novel 3D model classification and retrieval method, based on the PANORAMA representation and Convolutional Neural Networks, is presented. Initially, the 3D models are pose normalized using the SYMPAN method and consecutively ...
Towards a Principled Kernel Prediction for Spatially Varying BSSRDFs
(The Eurographics Association, 2018)
While the modeling of sub-surface translucency using homogeneous BSSRDFs is an established industry standard, applying the same approach to heterogeneous materials is predominantly heuristical. We propose a more principled ...
Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ...
Unifying Color and Texture Transfer for Predictive Appearance Manipulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Recent color transfer methods use local information to learn the transformation from a source to an exemplar image, and then transfer this appearance change to a target image. These solutions achieve very successful results ...
MCFTLE: Monte Carlo Rendering of Finite-Time Lyapunov Exponent Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Traditionally, Lagrangian fields such as finite-time Lyapunov exponents (FTLE) are precomputed on a discrete grid and are ray casted afterwards. This, however, introduces both grid discretization errors and sampling errors ...
Adaptive Sampling for On-The-Fly Ray Casting of Particle-based Fluids
(The Eurographics Association, 2016)
We present a fast and accurate ray casting technique for unstructured and dynamic particle sets. Our technique focuses on efficient, high quality volume rendering of fluids for computer animation and scientific applications. ...
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 ...
A Framework for Compact and Improved Panoramic VR Dissemination
(The Eurographics Association, 2016)
Panoramic capture devices in Cultural Heritage are becoming widely available to consumer market, also due to comfortable interactive online dissemination and to the growth of VR segment. VR fruition through an HMD although, ...
Visualization of Particle-based Data with Transparency and Ambient Occlusion
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Particle-based simulation techniques, like the discrete element method or molecular dynamics, are widely used in many research fields. In real-time explorative visualization it is common to render the resulting data using ...
