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 ...
Approximating Functions on a Mesh with Restricted Voronoï Diagrams
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose a method that computes a piecewise constant approximation of a function defined on a mesh. The approximation is associated with the cells of a restricted Voronoï diagram. Our method optimizes an objective function ...
Line-Sweep Ambient Obscurance
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Screen-space ambient occlusion and obscurance have become established methods for rendering global illumi- nation effects in real-time applications. While they have seen a steady line of refinements, their computational ...
An Area-Preserving Parametrization for Spherical Rectangles
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present an area-preserving parametrization for spherical rectangles which is an analytical function with domain in the unit rectangle [0;1]2 and range in a region included in the unit-radius sphere. The parametrization ...
Towards a Practical Gamut of Appearance Acquisition
(The Eurographics Association, 2013)
We propose discussing the performance of appearance modeling in terms of supported material and illumination gamut. While we have a precise understanding of the cost of any given appearance modeling method, performance is ...
BTF-based Material Representations: Current Challenges
(The Eurographics Association, 2013)
The development of Bidirectional Texture Functions (BTFs) has made it possible for a wide range of different materials to acquire their characteristic appearance from a real-world counterpart and reproduce it faithfully ...
