ShutterApp: Spatio-temporal Exposure Control for Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
A camera's shutter controls the incoming light that is reaching the camera sensor. Different shutters lead to wildly different results, and are often used as a tool in movies for artistic purpose, e.g., they can indirectly ...
A Multi-pass Method for Accelerated Spectral Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Spectral Monte Carlo rendering can simulate advanced light phenomena, such as chromatic dispersion, but typically shows a slow convergence behavior. Properly sampling the spectral domain can be challenging in scenes with ...
Geometric Sample Reweighting for Monte Carlo Integration
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Numerical integration is fundamental in multiple Monte Carlo rendering problems. We present a sample reweighting scheme, including underlying theory, and analysis of numerical performance for the integration of an unknown ...
A Practical and Efficient Approach for Correct Z-Pass Stencil Shadow Volumes
(The Eurographics Association, 2019)
Shadow volumes are a popular technique to compute pixel-accurate hard shadows in 3D scenes. Many variants exist that trade off accuracy and efficiency. In this work, we present an artifact-free, efficient, and easy-to-implement ...
Interactive Depixelization of Pixel Art through Spring Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2023)
We introduce an approach for converting pixel art into high-quality vector images. While much progress has been made on automatic conversion, there is an inherent ambiguity in pixel art, which can lead to a mismatch with ...
Editing Compressed High-resolution Voxel Scenes with Attributes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)
Sparse Voxel Directed Acyclic Graphs (SVDAGs) are an efficient solution for storing high-resolution voxel geometry. Recently, algorithms for the interactive modification of SVDAGs have been proposed that maintain the ...
