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 ... -
Herramientas para la Triangulación y Registrado Inicial de Modelos 3D a Partir de Nubes de Puntos
(The Eurographics Association, 2008)Presentamos un sistema para el tratamiento de datos adquiridos mediante escáner láser 3D, cuyo objetivo es la obtención de modelos tridimensionales de manera semiautomática. El sistema, que preserva el histórico de operaciones ... -
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
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)Hexahedral (or Hex‐) meshes are preferred in a number of scientific and engineering simulations and analyses due to their desired numerical properties. Recent state‐of‐the‐art techniques can generate high‐quality hex‐meshes. ... -
HexBox: Interactive Box Modeling of Hexahedral Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We introduce HexBox, an intuitive modeling method and interactive tool for creating and editing hexahedral meshes. Hexbox brings the major and widely validated surface modeling paradigm of surface box modeling into the ... -
Hidden contours on a frame-buffer
(The Eurographics Association, 1992)To comply with drafting practices and because shaded images do not always reveal the internal or hiddenstructures of 3D models, designers need wireframe images with hidden lines dashed and nonconlour tesselation edges ... -
The Hidden Face Determination Tree
(Eurographics Association, 1998)Hidden surface removal can be achieved using the Priority Face Determination (PFD) tree to create a priority ordering of n polygons in log4=3 n time. In this paper, we describe the Hidden Face Determi- nation (HFD) tree ... -
Hidden Lines using the EXCELL Method
(Blackwell Publishing Ltd and the Eurographics Association, 1982)The Extendible cell (EXCELL) method provides a data structure for efficient coordinate based access. It stores geometric data into computer storage blocks corresponding to disjoint variable sized rectangular cells accessible ... -
Hidden Octree Node Removal as a Pipeline Process
(Blackwell Publishing Ltd and the Eurographics Association, 1989)A processing pipeline solution to the generation and display of octree encoded 3-D objects is described. Particular emphasis is given to an algorithm which removes that part a of linear octree code which describes parts ... -
Hidden Surface Elimination on Parallel Processors
(Blackwell Science Ltd and the Eurographics Association, 1992)With the wide availability of general purpose parallel computers, there is a need to reconsider hidden surface elimination (HSE) algorithms with respect to parallel implementation. This paper considers MIMD parallel ... -
A Hidden-picture Puzzles Generator
(The Eurographics Association and Blackwell Publishing Ltd, 2008)A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line ... -
HidingGAN: High Capacity Information Hiding with Generative Adversarial Network
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Image steganography is the technique of hiding secret information within images. It is an important research direction in the security field. Benefitting from the rapid development of deep neural networks, many steganographic ... -
Hierarchical Additive Poisson Disk Sampling
(The Eurographics Association, 2018)Generating samples of point clouds and meshes with blue noise characteristics is desirable for many applications in rendering and geometry processing. Working with laser-scanned or lidar point clouds, we usually find region ... -
