Hemispherical Rasterization for Self-Shadowing of Dynamic Objects
(The Eurographics Association, 2004)We present a method for interactive rendering of dynamic models with self-shadows due to time-varying, lowfrequency lighting environments. In contrast to previous techniques, the method is not limited to static or preanimated ... -
Heresy: A Virtual Image-Space 3D Rasterization Architecture
(The Eurographics Association, 1997)With the advent of virtual reality and other visual applications that require photo and cinema realism, 3D graphics hardware has started to enter into the main stream. This paper describes the design and evaluation of a ... -
Heritage Move. A Natural and Lightweight Navigation Schema for Low-Cost, Non-Stationary Immersive Virtual Environments
(IEEE, 2015)Experiencing 3D models of historical reconstructions and places is still an active issue considering the wide variety of displaying and interaction devices for immersive Virtual Reality. Moreover, as standards are missing, ... -
Heritage Pieces Integration in Autonomous Augmented Reality Systems: Key problems and Solutions
(The Eurographics Association, 2008)Nowadays virtual reality users and professionals demand a growing quality and a higher degree of realism in development and applications. Among these technologies augmented reality systems stand out due to their complexity ... -
HerMeS - HERitage sMart social mEdia aSsistant: from Requirement Elicitation to Data Modelling for Feeding Artificial Intelligence Recommendation System
(The Eurographics Association, 2023)In the last years, several mobile APPs have been developed within the cultural tourism domain to give new impetus to this sector which is booming both in Italy and worldwide. In the wake of the increasing importance of ... -
Hermite Interpolation of Heightmaps
(The Eurographics Association, 2022)Heightmaps are ubiquitous in real-time computer graphics. They are used to describe geometric detail over an underlying coarser surface. Various techniques, such as parallax occlusion mapping and relief mapping, use heightmap ... -
Hermite Radial Basis Functions Implicits
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The Hermite radial basis functions (HRBF) implicits reconstruct an implicit function which interpolates or approximates scattered multivariate Hermite data (i.e. unstructured points and their corresponding normals). ... -
Hermitian B-Splines
(Blackwell Publishers Ltd and the Eurographics Association, 1999)This paper proposes to study a spline model, called HB-splines, that is in fact a B-spline representation of Hermite splines, combined with some restriction on the differential values at segment boundaries. Although this ... -
The HERO Algorithm for Ray-Tracing Octrees
(The Eurographics Association, 1989)An algorithm is presented for rapid traversal of octree data structures, in order to enhance the speed of ray tracing for scenes of high complexity. At each level of the octree, the algorithm generates the addresses of ... -
Hero Wavelength Spectral Sampling
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a spectral rendering technique that offers a compelling set of advantages over existing approaches. The key idea is to propagate energy along paths for a small, constant number of changing wavelengths. The first ... -

Hex Me If You Can
(The Eurographics Association and John Wiley & Sons Ltd., 2022)HexMe consists of 189 tetrahedral meshes with tagged features and a workflow to generate them. The primary purpose of HexMe meshes is to enable consistent and practically meaningful evaluation of hexahedral meshing algorithms ... -
Hexagonal Storage Scheme for Interleaved Frame Buffers and Textures
(The Eurographics Association, 2005)This paper presents a storage scheme which statically assigns pixel/texel coordinates to multiple memory banks in order to minimize frame buffer and texture memory access load imbalance. In this scheme, the pixels stored ... -
Hexahedral Mesh Adaptation to Imprint Geometric Details: Application to CAD Models
(The Eurographics Association, 2014)A novel algorithm is proposed to modify any unstructured hexahedral mesh in order to diminish the global time of numerical simulation processes, like optimization process and parametric studies. It consists in an imprinting ... -
Hexahedral Mesh Repair via Sum-of-Squares Relaxation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)The validity of trilinear hexahedral (hex) mesh elements is a prerequisite for many applications of hex meshes, such as finite element analysis. A commonly used check for hex mesh validity evaluates mesh quality on the ... -
Hexahedral Meshing With Varying Element Sizes
