Sparse Representation and Visualization for Direct Numerical Simulation of Premixed Combustion
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Direct Numerical Simulations of premixed combustion produce terabytes of raw data, which are prohibitively large to be stored, and have to be analyzed and visualized. A simultaneous and integrated treatment of data storage, ... -
Sparse Representation of Terrains for Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper, we present a simple and efficient method to represent terrains as elevation functions built from linear combinations of landform features (atoms). These features can be extracted either from real world ... -
Sparse Rig Parameter Optimization for Character Animation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose a novel motion retargeting method that efficiently estimates artist-friendly rig space parameters. Inspired by the workflow typically observed in keyframe animation, our approach transfers a source motion into ... -
Sparse Sampling for Image-Based SVBRDF Acquisition
(The Eurographics Association, 2016)We acquire the data-driven spatially-varying (SV)BRDF of a flat sample from only a small number of images (typically 20). We generalize the homogenous BRDF acquisition work of Nielsen et al., who derived an optimal minmal ... -
SparseBTF: Sparse Representation Learning for Bidirectional Texture Functions
(The Eurographics Association, 2023)We propose a novel dictionary-based representation learning model for Bidirectional Texture Functions (BTFs) aiming at compact storage, real-time rendering performance, and high image quality. Our model is trained once, ... -
Sparsely Precomputing The Light Transport Matrix for Real-Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Precomputation-based methods have enabled real-time rendering with natural illumination, all-frequency shadows, and global illumination. However, a major bottleneck is the precomputation time, that can take hours to days. ... -
Spatial Adjacency Maps for Translucency Simulation under General Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Rendering translucent materials in real time is usually done by using surface diffusion and/or (translucent) shadow maps. The downsides of these approaches are, that surface diffusion cannot handle translucency effects ... -
Spatial Aggregation of Mobile Transect Measurements for the Identification of Climatic Microenvironments
(The Eurographics Association, 2015)Mobile transect measurements retrieve high-resolution observations revealing the spatial variation of atmospheric properties throughout an urban landscape. A sensor platform is moved through a study site with varying urban ... -
Spatial Deformation Transfer
(ACM SIGGRAPH / Eurographics Association, 2009)Much effort is invested in generating natural deformations of three-dimensional shapes. Deformation transfer simplifies this process by allowing to infer deformations of a new shape from existing deformations of a similar ... -
Spatial Directional Radiance Caching
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a new approach for accelerated global illumination computation in scenes with glossy surfaces. Our algorithm combines sparse illumination computation used in the radiance caching algorithm with BRDF importance ... -
Spatial Interaction for the Post-Processing of 3D CFD Datasets
(The Eurographics Association, 2017)Virtual Reality visualizations are often used for the evaluation of three-dimensional datasets generated by Computational Fluid Dynamic (CFD) simulations. Several different tracked devices, such as pointers or data gloves, ... -
Spatial Keyframing for Performance-driven Animation
(The Eurographics Association, 2005)This paper introduces spatial keyframing, a technique for performance-driven character animation. In traditional temporal keyframing, key poses are defined at specific points in time: i.e., we define a map from a set of ... -
Spatial Matching of Animated Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper presents a new technique which makes use of deformation and motion properties between animated meshes for finding their spatial correspondences. Given a pair of animated meshes exhibiting a semantically similar ... -
Spatial Opacity Maps for Direct Volume Rendering of Regions of Interest
(The Eurographics Association, 2016)Despite the mature state of the volume rendering field, its adoption in medical applications is hindered by its complex parametrization and control, and 2D slice based tools are still preferred for clinical workflows. In ... -
Spatial Patches - A Primitive for 3D Model Representation
(Blackwell Publishers Ltd and the Eurographics Association, 2001)The commonly used solution for real-life 3D model representation is polygonal spatially consistent geometry, with texture, and, optionally, bump or displacement maps attached. Although the idea of displacement mapping is ... -
Spatial Recognition and Grouping of Text and Graphics
(The Eurographics Association, 2004)We present a framework for simultaneous grouping and recognition of shapes and symbols in free-form ink diagrams. The approach is completely spatial, that is it does not require any ordering on the strokes. It also does ... -
A Spatial Representation for Ray-Scene Intersection Test Improvement in Complex Scenes
(Eurographics Association, 2003)We present a spatial representation based on a hierarchical structure using the well-known spatial indexing structure called octree. There are very useful spatial representations for scenes whose objects can be distributed ... -
Spatial Splits in Bounding Volume Hierarchies
(The Eurographics Association, 2009)Bounding volume hierarchies (BVH) have become a widely used alternative to kD-trees as the acceleration structure of choice in modern ray tracing systems. However, BVHs adapt poorly to nonuniformly tessellated scenes, which ... -
Spatial Transfer Functions - A Unified Approach to Specifying Deformation in Volume Modeling and Animation
(The Eurographics Association, 2003)In this paper, we introduce the concept of spatial transfer functions as a unified approach to volume modeling and animation. A spatial transfer function is a function that defines the geometrical transformation of a scalar ... -
SPATIAL VIDEO Exploring Space Using Multiple Digital Videos
(The Eurographics Association, 2001)This paper pre sents and discusses a new approach to collect, organize and explore multiple digital videos on a spatial basis. We present a methodology based on direct video frame indexation to the real space represented ...
