An Efficient Denoising Algorithm for Global Illumination
(ACM, 2017)
We propose a hybrid ray-tracing/rasterization strategy for real- time rendering enabled by a fast new denoising method. We factor global illumination into direct light at rasterized primary surfaces and two indirect lighting ...
High-Performance Image Filters via Sparse Approximations
(ACM, 2020)
We present a numerical optimization method to find highly efficient (sparse) approximations for convolutional image filters. Using a modified parallel tempering approach,we solve a constrained optimization that maximizes ...
Improving Perception of Molecular Surface Visualizations by Incorporating Translucency Effects
(The Eurographics Association, 2018)
Molecular surfaces are a commonly used representation in the analysis of molecular structures as they provide a compact description of the space occupied by a molecule and its accessibility. However, due to the high ...
Ernst Grube: A Contemporary Witness and His Memories Preserved with Volumetric Video
(The Eurographics Association, 2020)
''Ernst Grube - The Legacy'' is an immersive Virtual Reality documentary about the life of Ernst Grube, one of the last German Holocaust survivors. From interviews conducted inside a volumetric capture studio, dynamic ...
Vectorized Production Path Tracing
(ACM, 2017)
This paper presents MoonRay, a high performance production rendering architecture using Monte Carlo path tracing developed at DreamWorks Animation. MoonRay is the first production path tracer, to our knowledge, designed ...
Sketch and Shade : An interactive assistant for sketching and shading
(Association for Computing Machinery, Inc (ACM), 2017)
We present a drawing assistant for sketching and for assisting users in shading a hand drawn sketch. The augmented reality based system uses a sketch made by a professional and uses it to help inexperienced users to do ...
Rapid k-d Tree Construction for Sparse Volume Data
(The Eurographics Association, 2018)
While k-d trees are known to be effective for spatial indexing of sparse 3-D volume data, full reconstruction, e.g. due to changes to the alpha transfer function during rendering, is usually a costly operation with this ...
Adaptive Filtering of Physical-Virtual Artifacts for Synthetic Animatronics
(The Eurographics Association, 2018)
Spatial Augmented Reality (SAR), e.g., based on monoscopic projected imagery on physical three-dimensional (3D) surfaces, can be particularly well-suited for ad hoc group or multi-user augmented reality experiences since ...
Generalized Light Portals
(ACM, 2020)
Light portals are useful for accelerating the convergence of Monte Carlo path tracing when rendering interiors. However, they are generally limited to flat polygonal shapes. In this paper, we introduce a new concept that ...
Real-Time Ray Tracing on Head-Mounted-Displays for Advanced Visualization of Sheet Metal Stamping Defects
(The Eurographics Association, 2019)
Although interactive ray tracing has been around since the late 1990s, real-time frame rates had so far only been feasible for low and mid-size screen resolutions. Recent developments in GPU hardware, that specifically ...
