Appearance of Interfaced Lambertian Microfacets, using STD Distribution
(The Eurographics Association, 2017)
This paper presents the use of Student’s T-Distribution (STD) with interfaced Lambertian (IL) microfacets. The resulting model increases the range of materials while providing a very accurate adjustment of appearance. STD ...
Reducing Anisotropic BSDF Measurement to Common Practice
(The Eurographics Association, 2014)
We address the problem of measuring and representing reflection and transmission for anisotropic materials without relying on mathematical models or a large sample database. By eliminating assumptions of material behavior, ...
Fast Robust and Precise Shadow Algorithm for WebGL 1.0 Platform
(The Eurographics Association, 2015)
This paper presents fast and robust per-sample correct shadows for WebGL platform. The algorithm is based on silhouette shadow volumes and it rivals the standard shadow mapping performance. Our performance is usually ...
Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...
Geometric Accuracy Analysis of Stationary BTF Gonioreflectometers
(The Eurographics Association, 2015)
The accurate BTF data representation requires specialized measurement gantries, some of them designed as gonireflectometers. These consist of an illumination source and a camera mounted on two robotic arms, one degree of ...
Automatic Lighting Design from Photographic Rules
(The Eurographics Association, 2016)
Lighting design is crucial in 3D scenes modeling for its ability to provide cues to understand the objects shape. However a lot of time, skills, trials and errors are required to obtain a desired result. Existing automatic ...
Grand Challenges: Material Models in the Automotive Industry
(The Eurographics Association, 2013)
Material reflectance definitions are core to high fidelity visual simulation of objects within a compelling 3D scene. In the automotive industry these are used across the entire business process: from conceptualisation of ...
Online Reconstruction of Textured Triangle Meshes from Aerial Images
(The Eurographics Association, 2013)
In this paper we present and evaluate a new online reconstruction algorithm to create a textured triangle mesh from a set of aerial images via an unorganized point cloud. Both the point cloud and the mesh are iteratively ...
Experimental Analysis of BSDF Models
(The Eurographics Association, 2017)
The Bidirectional Scattering Distribution Function (BSDF) describes the appearance of an optically thin, translucent material by its interaction with light at a surface point. Various BSDF models have been proposed to ...
Combining Pseudo Chroma Depth Enhancement and Parameter Mapping for Vascular Surface Models
(The Eurographics Association, 2017)
The presence of depth cues in a visualization can be a great aid in understanding the structure and topology of a vessel tree. Pseudo Chromadepth is a well-known technique for enhancing depth perception in vascular 3D ...
