Direct Volume Rendering from Photographic Data
(The Eurographics Association, 2000)Direct volume rendering from photographic volume data has the potential to create realistic images of internal volume structure, as well as the structure of boundaries within the volume. While possession of the photographic ... -
Direct Volume Rendering of Photographic Volumes Using Multi-Dimensional Color-Based Transfer Functions
(The Eurographics Association, 2002)Traditionally, volume rendering of medical data has been comprised of transfer functions that map a scalar value, usually a MRI or CT intensity, to an opacity. Corresponding color maps are either selected regardless of the ... -
Direct Volume Rendering of Stack-Based Terrains
(The Eurographics Association, 2017)Traditionally, the rendering of volumetric terrain data, as many other scientific 3D data, has been carried out performing direct volume rendering techniques on voxel-based representations. A main problem with this kind ... -
Directable Animation of Elastic Objects
(The Eurographics Association, 2005)There is a crucial demand in the computer animation industry to make animations that blend animator-specified expressive motion with physics-based realism. We propose a novel framework to create directable animation of ... -
Directable Photorealistic Liquids
(The Eurographics Association, 2004)We present a method for the directable animation of photorealistic liquids using the particle level set method to obtain smooth, visually pleasing complex liquid surfaces. We also provide for a degree of control common to ... -
Directed Acyclic Graph Encoding for Compressed Shadow Maps
(The Eurographics Association, 2021)Detailed shadows in large-scale environments are challenging. Our approach enables efficient detailed shadow computations for static environments at a low memory cost. It builds upon compressed precomputed multiresolution ... -
Directed Curvature Histograms for Robotic Grasping
(The Eurographics Association, 2017)Three-dimensional descriptors are a common tool nowadays, used in a wide range of tasks. Most of the descriptors that have been proposed in the literature focus on tasks such as object recognition and identification. This ... -
Directing Gaze in 3D Models with Stylized Focus
(The Eurographics Association, 2006)We present an interactive system for placing emphasis in stylized renderings of 3D models. The artist chooses a camera position, an area of interest, and a rendering style for the scene. The system then automatically renders ... -
Directing the Photography: Combining Cinematic Rules, Indirect Light Controls and Lighting-by-Example
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The placement of lights in a 3D scene is a technical and artistic task that requires time and trained skills. Most 3D modelling tools only provide a direct control of light sources, through the manipulation of parameters ... -
Directional Discretized Occluders for Accelerated Occlusion Culling
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present a technique for accelerating the rendering of high depth-complexity scenes. In a preprocessing stage, we approximate the input model with a hierarchical data structure and compute simple view-dependent polygonal ... -
Directional Field Synthesis, Design, and Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Direction fields and vector fields play an increasingly important role in computer graphics and geometry processing. The synthesis of directional fields on surfaces, or other spatial domains, is a fundamental step in ... -
A Directional Occlusion Shading Model for Interactive Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2009)Volumetric rendering is widely used to examine 3D scalar fields from CT/MRI scanners and numerical simulation datasets. One key aspect of volumetric rendering is the ability to provide perceptual cues to aid in understanding ... -
Directionality-Aware Design of Embroidery Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Embroidery is a long-standing and high-quality approach to making logos and images on textiles. Nowadays, it can also be performed via automated machines that weave threads with high spatial accuracy. A characteristic ... -
Dirichlet Energy for Analysis and Synthesis of Soft Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Soft maps taking points on one surface to probability distributions on another are attractive for representing surface mappings in the presence of symmetry, ambiguity, and combinatorial complexity. Few techniques, however, ... -
Dirichlet Harmonic Shape Compression with Feature Preservation for Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)With the rapid advancement of 3D scanning devices, large and complicated 3D shapes are becoming ubiquitous, and require large amount of resources to store and transmit them efficiently. This makes shape compression a ... -
DIRT: Deferred Image-based Ray Tracing
(The Eurographics Association, 2016)We introduce a novel approach to image-space ray tracing ideally suited for the photorealistic synthesis of fully dynamic environments at interactive frame rates. Our method, designed entirely on the rasterization pipeline, ... -
Dirty Glass: Rendering Contamination on Transparent Surfaces
(The Eurographics Association, 2007)Rendering of clean transparent objects has been well studied in computer graphics. However, real-world transparent objects are seldom clean their surfaces have a variety of contaminants such as dust, dirt, and lipids. These ... -
DisArray: A 16x16 RasterOp Processor
(The Eurographics Association, 1983)RasterOp is a powerful primitive operation for raster graphics. To improve the execution rate of this operation, a machine with a set of 256 1-bit processors organised as a 16x16 array has been constructed. This machine ... -
