Spherical Fibonacci Point Sets for Illumination Integrals
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Quasi-Monte Carlo (QMC) methods exhibit a faster convergence rate than that of classic Monte Carlo methods. This feature has made QMC prevalent in image synthesis, where it is frequently used for approximating the value ...
Sparse GPU Voxelization of Yarn‐Level Cloth
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
Most popular methods in cloth rendering rely on volumetric data in order to model complex optical phenomena such as sub‐surface scattering. These approaches are able to produce very realistic illumination results, but their ...
Time‐Continuous Quasi‐Monte Carlo Ray Tracing
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
Domain‐continuous visibility determination algorithms have proved to be very efficient at reducing noise otherwise prevalent in stochastic sampling. Even though they come with an increased overhead in terms of geometrical ...
Real‐Time Solar Exposure Simulation in Complex Cities
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
In urban design, estimating solar exposure on complex city models is crucial but existing solutions typically focus on simplified building models and are too demanding in terms of memory and computational time. In this ...
Ray Accelerator: Efficient and Flexible Ray Tracing on a Heterogeneous Architecture
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a hybrid ray tracing system, where the work is divided between the CPU cores and the GPU in an integrated chip, and communication occurs via shared memory. Rays are organized in large packets that can be distributed ...
Stereo‐Consistent Contours in Object Space
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
Notebook scribbles, art or technical illustrations—line drawings are a simplistic method to visually communicate information. Automated line drawings often originate from virtual 3D models, but one cannot trivially experience ...
Enhanced Visualization of Detected 3D Geometric Differences
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
The wide availability of 3D acquisition devices makes viable their use for shape monitoring. The current techniques for the analysis of time‐varying data can efficiently detect actual significant geometric changes and rule ...
Improved Corners with Multi‐Channel Signed Distance Fields
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
We propose an extension to the state‐of‐the‐art text rendering technique based on sampling a 2D signed distance field from a texture. This extension significantly improves the visual quality of sharp corners, which is the ...
Large‐Scale Pixel‐Precise Deferred Vector Maps
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
Rendering vector maps is a key challenge for high‐quality geographic visualization systems. In this paper, we present a novel approach to visualize vector maps over detailed terrain models in a pixel‐precise way. Our method ...
Bidirectional Rendering of Vector Light Transport
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
On the foundations of many rendering algorithms it is the symmetry between the path traversed by light and its adjoint path starting from the camera. However, several effects, including polarization or fluorescence, break ...
