Quad-Based Fourier Transform for Efficient Diffraction Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Far-field diffraction can be evaluated using the Discrete Fourier Transform (DFT) in image space but it is costly due to its dense sampling. We propose a technique based on a closed-form solution of the continuous Fourier ... -
Runtime Shader Simplification via Instant Search in Reduced Optimization Space
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Traditional automatic shader simplification simplifies shaders in an offline process, which is typically carried out in a contextoblivious manner or with the use of some example contexts, e.g., certain hardware platforms, ... -
Spectral Gradient Sampling for Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Spectral Monte-Carlo methods are currently the most powerful techniques for simulating light transport with wavelengthdependent phenomena (e.g., dispersion, colored particle scattering, or diffraction gratings). Compared ... -
Stratified Sampling of Projected Spherical Caps
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a method for uniformly sampling points inside the projection of a spherical cap onto a plane through the sphere's center. To achieve this, we devise two novel area-preserving mappings from the unit square to ... -
Thin Structures in Image Based Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose a novel method to handle thin structures in Image-Based Rendering (IBR), and specifically structures supported by simple geometric shapes such as planes, cylinders, etc. These structures, e.g. railings, fences, ...
