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 ...
Adaptive BRDF-Oriented Multiple Importance Sampling of Many Lights
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Many-light rendering is becoming more common and important as rendering goes into the next level of complexity. However, to calculate the illumination under many lights, state of the art algorithms are still far from ...
Exact Constraint Satisfaction for Truly Seamless Parametrization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In the field of global surface parametrization a recent focus has been on so-called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of ...
Quantifying the Error of Light Transport Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
This paper proposes a new methodology for measuring the error of unbiased physically based rendering algorithms. The current state of the art includes mean squared error (MSE) based metrics and visual comparisons of ...
Flexible SVBRDF Capture with a Multi-Image Deep Network
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Empowered by deep learning, recent methods for material capture can estimate a spatially-varying reflectance from a single photograph. Such lightweight capture is in stark contrast with the tens or hundreds of pictures ...
Neural BTF Compression and Interpolation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
The Bidirectional Texture Function (BTF) is a data-driven solution to render materials with complex appearance. A typical capture contains tens of thousands of images of a material sample under varying viewing and lighting ...
Generating Color Scribble Images using Multi-layered Monochromatic Strokes Dithering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Color scribbling is a unique form of illustration where artists use compact, overlapping, and monochromatic scribbles at microscopic scale to create astonishing colorful images at macroscopic scale. The creation process ...
Compacting Voxelized Polyhedra via Tree Stacking
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Volume compaction is a geometric problem that aims to reduce the volume of a polyhedron via shape transform. Compactable structures are easier to transport and in some cases easier to manufacture, therefore, they are ...
Generating Stochastic Wall Patterns On-the-fly with Wang Tiles
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
The game and movie industries always face the challenge of reproducing materials. This problem is tackled by combining illumination models and various textures (painted or procedural patterns). Generating stochastic wall ...
A Generalized Cubemap for Encoding 360° VR Videos using Polynomial Approximation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
360° VR videos provide users with an immersive visual experience. To encode 360° VR videos, spherical pixels must be mapped onto a two-dimensional domain to take advantage of the existing video encoding and storage standards. ...
