Occluder Simplification Using Planar Sections
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method for extreme occluder simplification. We take a triangle soup as input, and produce a small set of polygons with closely matching occlusion properties. In contrast to methods that optimize the original ... -
On Near Optimal Lattice Quantization of Multi‐Dimensional Data Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)One of the most elementary application of a lattice is the quantization of real‐valued s‐dimensional vectors into finite bit precision to make them representable by a digital computer. Most often, the simple s‐dimensional ... -
On Perception of Semi‐Transparent Streamlines for Three‐Dimensional Flow Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)One of the standard techniques to visualize three‐dimensional flow is to use geometry primitives. This solution, when opaque primitives are used, results in high levels of occlusion, especially with dense streamline seeding. ... -
Photons: Evolution of a Course in Data Structures
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents the evolution of a data structures and algorithms course based on a specific computer graphics problem, namely, photon mapping, as the teaching medium. The paper reports development of the course through ... -
Projection Mapping on Arbitrary Cubic Cell Complexes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This work presents a new representation used as a rendering primitive of surfaces. Our representation is defined by an arbitrary cubic cell complex: a projection‐based parameterization domain for surfaces where geometry ... -
Robust Segmentation of Multiple Intersecting Manifolds from Unoriented Noisy Point Clouds
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method for extracting complex manifolds with an arbitrary number of (self‐) intersections from unoriented point clouds containing large amounts of noise. Manifolds are formed in a three‐step process. First, ... -
Scalable Realistic Rendering with Many‐Light Methods
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent years have seen increasing attention and significant progress in many‐light rendering, a class of methods for efficient computation of global illumination. The many‐light formulation offers a unified mathematical ... -
Stackless Multi‐BVH Traversal for CPU, MIC and GPU Ray Tracing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Stackless traversal algorithms for ray tracing acceleration structures require significantly less storage per ray than ordinary stack‐based ones. This advantage is important for massively parallel rendering methods, where ... -
Subdivision Surfaces with Creases and Truncated Multiple Knot Lines
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We deal with subdivision schemes based on arbitrary degree B‐splines. We focus on extraordinary knots which exhibit various levels of complexity in terms of both valency and multiplicity of knot lines emanating from such ... -
A Survey of Volumetric Illumination Techniques for Interactive Volume Rendering
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Interactive volume rendering in its standard formulation has become an increasingly important tool in many application domains. In recent years several advanced volumetric illumination techniques to be used in interactive ... -
Time Line Cell Tracking for the Approximation of Lagrangian Coherent Structures with Subgrid Accuracy
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Lagrangian coherent structures (LCSs) have become a widespread and powerful method to describe dynamic motion patterns in time-dependent flow fields. The standard way to extract LCS is to compute height ridges in the ... -
Visibility Silhouettes for Semi‐Analytic Spherical Integration
(The Eurographics Association and John Wiley and Sons Ltd., 2014)At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point‐sampling approaches, such as ray‐tracing or hardware ... -
Visualization of the Centre of Projection Geometrical Locus in a Single Image
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Single view reconstruction (SVR) is an important approach for 3D shape recovery since many non‐existing buildings and scenes are captured in a single image. Historical photographs are often the most precise source for ...
