Random Sparse Coded Aperture for Lensless Imaging
(The Eurographics Association, 2014)This paper develops a computational lensless imaging system based on a random sparse coded aperture. The camera consists of a thin mask with a coded pattern and a standard sensor array. The proposed coded aperture contains ... -
Real-Time Antialiased Area Lighting Using Multi-Scale Linearly Transformed Cosines
(The Eurographics Association, 2021)We present an anti-aliased real-time rendering method for local area lights based on Linearly Transformed Cosines (LTCs). It significantly reduces the aliasing artifacts of highlights reflected from area lights due to ... -
Real-time Collision Detection with Two-level Spatial Hashing on GPU
(The Eurographics Association, 2014)In this paper, a two-level parallel spatial hashing method is presented for real-time collision detection of deformable objects based on modern GPU architecture. The second-level of spatial hashing is used to improve the ... -
Real-time Content Projection onto a Tunnel from a Moving Subway Train
(The Eurographics Association, 2021)In this study, we present the first actual working system that can project content onto a tunnel wall from a moving subway train so that passengers can enjoy the display of digital content through a train window. To ... -
Real-time Particle Fluid Simulation with WCSPH
(The Eurographics Association, 2012)In this paper, based on weakly compressible smoothed particles hydrodynamics (WCSPH), we present a method for simulating high quality fluid. We propose a new pressure equation to reduce time overhead, speed up convergence ... -
Real-time Realistic Voxel-based Rendering
(The Eurographics Association, 2011)With the advance of graphics hardware, setting 3D texture as render target is newly available to allow voxelization algorithms to record the existence, color and normal information in a voxel directly without specific ... -
Real-time Rendering of Endless Cloud Animation
(The Eurographics Association, 2011)In this paper, we propose a real-time animation method for dynamic clouds illuminated by sunlight and skylight with multiple scattering. In order to create animations of outdoor scenes, it is necessary to render time-varying ... -
Real-time Shadow Removal using a Volumetric Skeleton Model in a Front Projection System
(The Eurographics Association, 2017)When a person is located between a display and a projector in operation, a shadow is cast on the display. The shadow on a display may eliminate important visual information and therefore adversely affects the viewing ... -
Reconstructing Baseball Pitching Motions from Video
(The Eurographics Association, 2023)Baseball is one of the most loved sports in the world. In baseball game, the pitcher's control ability is a key factor for determining the outcome of the game. There are a lot of video data shooting baseball games, and ... -
Reconstructing Bounding Volume Hierarchies from Memory Traces of Ray Tracers
(The Eurographics Association, 2022)The ongoing race to improve computer graphics leads to more complex GPU hardware and ray tracing techniques whose internal functionality is sometimes hidden to the user. Bounding volume hierarchies and their construction ... -
Reconstructing Monte Carlo Errors as a Blue-noise in Screen Space
(The Eurographics Association, 2020)We present a novel method that reconstructs the Monte Carlo errors of renderings as a blue-noise in screen space. To this end, we conform the statistic result of per-pixel integration to a precomputed blue-noise mask. ... -
Recovering 3D Indoor Floor Plans by Exploiting Low-cost Spherical Photography
(The Eurographics Association, 2018)We present a novel approach to automatically recover, from a small set of partially overlapping panoramic images, an indoor structure representation in terms of a 3D floor plan registered with a set of 3D environment maps. ... -
Reflectance and Shape Estimation for Cartoon Shaded Objects
(The Eurographics Association, 2016)Although many photorealistic relighting methods provide a way to change the illumination of objects in a digital photograph, it is currently difficult to relight a cartoon shading style in digital illustrations. The main ... -
