Deferred Attribute Interpolation for Memory-Efficient Deferred Shading
(ACM Siggraph, 2015)
In this work we present a novel approach to deferred shading suitable for high resolution displays and high visibility sampling rates. We reduce the memory costs of deferred shading by substituting the geometry buffer with ...
Moment-Based Opacity Optimization
(The Eurographics Association, 2020)
Geometric structures such as points, lines, and surfaces play a vital role in scientific visualization. However, these visualizations frequently suffer from visual clutter that hinders the inspection of important features ...
Path Guiding with Vertex Triplet Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Good importance sampling strategies are decisive for the quality and robustness of photorealistic image synthesis with Monte Carlo integration. Path guiding approaches use transport paths sampled by an existing base sampler ...
Guiding Light Trees for Many-Light Direct Illumination
(The Eurographics Association, 2023)
Path guiding techniques reduce the variance in path tracing by reusing knowledge from previous samples to build adaptive sampling distributions. The Practical Path Guiding (PPG) approach stores and iteratively refines an ...
Out-of-the-loop Autotuning of Metropolis Light Transport with Reciprocal Probability Binning
(The Eurographics Association, 2023)
The performance of Markov Chain Monte Carlo (MCMC) rendering methods depends heavily on the mutation strategies and their parameters. We treat the underlying mutation strategies as black-boxes and focus on their parameters. ...
Minimal Convolutional Neural Networks for Temporal Anti Aliasing
(The Eurographics Association, 2023)
Existing deep learning methods for performing temporal anti aliasing (TAA) in rendering are either closed source or rely on upsampling networks with a large operation count which are expensive to evaluate. We propose a ...
Markov Chain Mixture Models for Real-Time Direct Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2023)
We present a novel technique to efficiently render complex direct illumination in real-time. It is based on a spatio-temporal randomized mixture model of von Mises-Fisher (vMF) distributions in screen space. For every pixel ...
Perceptually Guided Automatic Parameter Optimization for Interactive Visualization
(The Eurographics Association, 2023)
We propose a new reference-free method for automatically optimizing the parameters of visualization techniques such that the perception of visual structures is improved. Manual tuning may require domain knowledge not only ...
