Self Tuning Texture Optimization

Mark Pauly, Boris Neubert, Alexandre Kaspar

The goal of example-based texture synthesis methods is to generate arbitrarily large textures from limited exemplars in order to fit the exact dimensions and resolution required for a specific modeling task. The challenge is to faithfully capture all of th ...

Rendering Glints on High-resolution Normal-mapped Specular Surfaces

Wenzel Alban Jakob

Complex specular surfaces under sharp point lighting show a fascinating glinty appearance, but rendering it is an unsolved problem. Using Monte Carlo pixel sampling for this purpose is impractical: the energy is concentrated in tiny highlights that take up ...

Discrete Stochastic Microfacet Models

Wenzel Alban Jakob

This paper investigates rendering glittery surfaces, ones which exhibit shifting random patterns of glints as the surface or viewer moves. It applies both to dramatically glittery surfaces that contain mirror-like flakes and also to rough surfaces that exh ...

Integrating non-visual effects of light into lighting simulation: challenges ahead

Marilyne Andersen, María Lovísa Ámundadóttir, Steven W. Lockley

Lighting is a major influential factor that affects human health and sense of wellbeing in the built environment. Since 2002, when the first reports on the discovery of a novel type of photoreceptor were published, a new field of study started to emerge at ...

Modeling (non-)uniform scattering distributions in geometrical acoustics

Dirk Schröder

In most cases, a surface is not ideally smooth. It rather contains regular and irregular dents, bumps and other textures that influence the reflection of the incident wave. A reflection on such a corrugated surface causes a frequency-dependent redirection ...

Resolving Ambiguities in Monocular 3D Reconstruction of Deformable Surfaces

Aydin Varol

In this thesis, we focus on the problem of recovering 3D shapes of deformable surfaces from a single camera. This problem is known to be ill-posed as for a given 2D input image there exist many 3D shapes that give visually identical projections. We present ...

Caustic Art

Mark Pauly

The computation of caustics created by reflection or refraction of light is a well-studied problem in computer graphics. This paper investigates the inverse problem: Given a greyscale intensity image, find the shape of a surface that will cast a caustic th ...

A new device for dynamic luminance mapping and glare risk assessment in buildings

Jean-Louis Scartezzini, Laurent Deschamps, Apiparn Borisuit

High dynamic range imaging has been shown to be a reliable tool to assess luminance maps and glare risk probability in buildings. However, there are some limitations of image capturing time, especially when dealing with highly dynamic and contrasted daylig ...

Dynamic Annual Metrics for Contrast in Daylit Architecture

Marilyne Andersen, Siobhan Francois Rockcastle

Daylight is a dynamic source of illumination in architectural space, creating diverse and ephemeral configurations of light and shadow within the built environment. It can generate contrasting levels of brightness between distinct geometries or it can high ...

Monocular 3D Reconstruction of Locally Textured Surfaces

Pascal Fua, Mathieu Salzmann, Appu Shaji, Aydin Varol

Most recent approaches to monocular non-rigid 3D shape recovery rely on exploiting point correspondences and work best when the whole surface is well-textured. The alternative is to rely either on contours or shading information, which has only been demons ...
