Level-of-Detail Streaming and Rendering using Bidirectional Sparse Virtual Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Bidirectional Texture Functions (BTFs) are among the highest quality material representations available today and thus well suited whenever an exact reproduction of the appearance of a material or complete object is required. ...
Patch-based Texture Interpolation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
In this paper, we present a novel exemplar-based technique for the interpolation between two textures that combines patch-based and statistical approaches. Motivated by the notion of texture as a largely local phenomenon, ...
Heightfield and spatially varying BRDF Reconstruction for Materials with Interreflections
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Photo-realistic reproduction of material appearance from images has widespread use in applications ranging from movies over advertising to virtual prototyping. A common approach to this task is to reconstruct the small ...
Data Driven Surface Reflectance from Sparse and Irregular Samples
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
In recent years, measuring surface reflectance has become an established method for high quality renderings. In this context, especially non-parametric representations got a lot of attention as they allow for a very accurate ...
Example-based Interpolation and Synthesis of Bidirectional Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Bidirectional Texture Functions (BTF) have proven to be a well-suited representation for the reproduction of measured real-world surface appearance and provide a high degree of realism. We present an approach for designing ...
WebGL-based Streaming and Presentation Framework for Bidirectional Texture Functions
(The Eurographics Association, 2011)
Museums and Cultural Heritage institutions have a growing interest in presenting their collections to a broader community via the Internet. The photo-realistic presentation of interactively inspectable digital 3D replicas ...
Integrated High-Quality Acquisition of Geometry and Appearance for Cultural Heritage
(The Eurographics Association, 2011)
Current research trends demonstrate that, for a wide range of applications in cultural heritage, 3D shape acquisition alone is not sufficient. To generate a digital replica of a real world object the digitized geometric ...
BTF Compression via Sparse Tensor Decomposition
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper, we present a novel compression technique for Bidirectional Texture Functions based on a sparse tensor decomposition. We apply the K-SVD algorithm along two different modes of a tensor to decompose it into a ...
Parallelized Matrix Factorization for fast BTF Compression
(The Eurographics Association, 2009)
Dimensionality reduction methods like Principal Component Analysis (PCA) have become commonplace for the compression of large datasets in computer graphics. One important application is the compression of Bidirectional ...
