Spherical Harmonic Gradients for Mid-Range Illumination
(The Eurographics Association, 2004)Spherical harmonics are often used for compact description of incident radiance in low-frequency but distant lighting environments. For interaction with nearby emitters, computing the incident radiance at the center of an ... -
Spherical Harmonic Lighting of Wavelength-Dependent Phenomena
(The Eurographics Association, 2005)Rendering of objects that exhibit iridescence has previously been limited to simple lighting conditions generated from a few point or directional lights. We extend this idea by modeling light interference as a Bidirectional ... -
Spherical Parametric Measurement for Continuous and Balanced Mesh Segmentation
(The Eurographics Association, 2023)Mesh segmentation is an important process for building the discrete mesh structure used on the GPU to accelerate geometry processing applications. In this paper, we introduce a novel mesh segmentation method that creates ... -
Spherical Q2-tree for Sampling Dynamic Environment Sequences
(The Eurographics Association, 2005)Previous methods in environment map sampling seldom consider a sequence of dynamic environment maps. The generated sampling patterns of the sequence may not maintain the temporal illumination consistency and result in ... -
Spherical Triangular B-splines with Application to Data Fitting
(Blackwell Science Ltd and the Eurographics Association, 1995)Triangular B-splines surfaces are a tool for representing arbitrary piecewise polynomial surfaces over planar triangulations, while automatically maintaining continuity properties across patch boundaries. Recently, Alfeld ... -
Spherical Visibility Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located ... -
SPIDER: SPherical Indoor DEpth Renderer
(The Eurographics Association, 2022)Today's Extended Reality (XR) applications that call for specific Diminished Reality (DR) strategies to hide specific classes of objects are increasingly using 360? cameras, which can capture entire areas in a single ... -
Spinnstube: A Seated Augmented Reality Display System
(The Eurographics Association, 2007)We describe the Spinnstube, a new projection-based Augmented Reality display system for collaborative work environments. By simply attaching the system to a desk, real objects are augmented with virtual objects by using a ... -
Spinoff - Transferring Energy between Real and Virtual Worlds
(The Eurographics Association, 2007)There is a widening gap between interaction devices for Virtual Environments and other factors such as graphical realism, accessibility and complexity. To address this problem, we developed a Mixed Reality environment that ... -
Spiral Theme Plot
(The Eurographics Association, 2016)We introduce a new visualization method for temporal data, Spiral Theme Plot, by combining ThemeRiver method, spiral patterns, and scatter plot technique. Similar to ThemeRiver, data in different categories (themes) are ... -
SPIRIT - Entertaining Encounters with Ancient History
(The Eurographics Association, 2014)The paper describes the ongoing project "SPIRIT", in particular the design of novel and entertaining forms of heritage communications through mobile augmented reality. The SPIRIT concept is based upon a strong storytelling ... -
Spiritual Art: Evoking the Numinous using a 3D Computer Game Engine
(The Eurographics Association, 2007)The Seven Valleys is an interactive 3D installation based artwork inspired by mystical writings of the Bahá'í Faith. Created as a modification of the first-person shooter Unreal Tournament 2003 it subverts the original ... -
Spirograph inspired visualization of ecological networks
(ACM, 2014)Ecological networks are directed weighted graphs for representing direct and indirect relationships between species in ecosystems. These complex cyclic networks play an important role in understanding an ecosystem's dynamics. ... -
Splash in a Flash: Sharpness-aware Minimization for Efficient Liquid Splash Simulation
(The Eurographics Association, 2022)We present sharpness-aware minimization (SAM) for fluid dynamics which can efficiently learn the plausible dynamics of liquid splashes. Due to its ability to achieve robust and generalizing solutions, SAM efficiently ... -
Splat/Mesh Blending, Perspective Rasterization and Transparency for Point-Based Rendering
(The Eurographics Association, 2006)In this paper we present multiple simple and efficient improvements for splatting based rendering systems. In a first step we derive a perspectively correct splat rasterization algorithm suitable for both efficient ... -
Splatting the Lines in Parallel Coordinates
(The Eurographics Association and Blackwell Publishing Ltd., 2009)coordinates. Our framework consists of two major components: a polyline splatter for cluster detection and a segment splatter for clutter reduction. The cluster detection is performed by splatting the lines one by one into ... -
Splatting With Shadows
(The Eurographics Association, 2001)In this paper we describe an efficient approach to add shadows to volumetric scenes. The light emitted by the lightsource is properly attenuated by the intervening volumetric structures before it is reflected towards the ... -
Splicing Upper-Body Actions with Locomotion
(The Eurographics Association and Blackwell Publishing, Inc, 2006)This paper presents a simple and efficient technique for synthesizing high-fidelity motions by attaching, or splicing, the upper-body action of one motion example to the lower-body locomotion of another. Existing splicing ... -
Spline Approximation of General Volumetric Data
(The Eurographics Association, 2004)We present an efficient algorithm for approximating huge general volumetric data sets, i.e. the data is given over arbitrarily shaped volumes and consists of up to millions of samples. The method is based on cubic trivariate ... -
Spline-based Decomposition of Streamed Particle Trajectories for Efficient Transfer and Analysis
(The Eurographics Association, 2017)We introduce an approach for distributed processing and efficient storage of noisy particle trajectories, and present visual analysis techniques that directly operate on the generated representation. For efficient storage, ...
