TL;DR: This work presents an algebraic framework, called Constructive Volume Geometryn (CVG), for modelling complex spatial objects using combinational operations, and describes the interior as well as the exterior of objects.
Abstract: We present an algebraic framework, called Constructive Volume Geometry (CVG), for modelling complex spatial objects using combinational operations. By utilising scalar elds as fundamental building blocks, CVG provides high-level algebraic representations of objects that are dened mathematically or built upon sampled or simulated datasets. It models amorphous phenomena as well as solid objects, and describes the interior as well as the exterior of objects. We also describe a hierarchical representation scheme for CVG, and a direct rendering method with a new approach for consistent sampling. The work has demonstrated the feasibility of combining a variety of graphics data types in a coherent modelling scheme.

TL;DR: An algorithm is presented that directly computes the multiple merging trajectories that may have constituted the system's past and makes accessible the explicit portraits of these mathematical objects through computer-generated graphics.
Abstract: The book introduces a powerful new global perspective for the study of discrete dynamical systems. After first looking at the unique trajectory of a system's future, an algorithm is also presented that directly computes the multiple merging trajectories that may have constituted the system's past. A given set of cellular parameters will, in a sense, crystallize state space into a set of basins of attraction that will typically have the topology of branching trees rooted on attractor cycles. The book makes accessible the explicit portraits of these mathematical objects through computer-generated graphics. (Book/disk package disk requires an 80286, or higher, IBM PC or compatible with 640K of memory, VGA graphics, and DOS 2.0 or higher.

TL;DR: XML3D as discussed by the authors is a declarative approach that leverages existing web technologies including HTML, Cascading Style Sheets (CSS), the Document Object Model (DOM), and AJAX for dynamic content.
Abstract: Web technologies provide the basis to distribute digital information worldwide and in realtime but they have also established the Web as a ubiquitous application platform. The Web evolved from simple text data to include advanced layout, images, audio, and recently streaming video. Today, as our digital environment becomes increasingly three-dimensional (e.g. 3D cinema, 3D video, consumer 3D displays, and high-performance 3D processing even in mobile devices) it becomes obvious that we must extend the core Web technologies to support interactive 3D content.
Instead of adapting existing graphics technologies to the Web, XML3D uses a more radical approach: We take today's Web technology and try to find the minimum set of additions that fully support interactive 3D content as an integral part of mixed 2D/3D Web documents.
XML3D enables portable cross-platform authoring, distribution, and rendering of and interaction with 3D data. As a declarative approach XML3D fully leverages existing web technologies including HTML, Cascading Style Sheets (CSS), the Document Object Model (DOM), and AJAX for dynamic content. All 3D content is exposed in the DOM, fully supporting DOM scripting and events, thus allowing Web designers to easily apply their existing skills. The design of XML3D is based on modern programmable graphics hardware, e.g. supports efficient mapping to GPUs without maintaining copies. It also leverages a new approach to specify shaders independently of specific rendering techniques or graphics APIs. We demonstrated the feasibility of our approach by integrating XML3D support into two major open browser frameworks from Mozilla and WebKit as well as providing a portable implementation based on JavaScript and WebGL.

TL;DR: This work presents here their first efforts in implementing two different versions of visual feedback to permit the robot to iteratively augment and improve a drawing which initially is built from a process of salient lines recovery, and presents the arguments in favour of such a position for the graphics community to reflect upon.

TL;DR: In this paper, the authors present strategies for the visual display and analysis of geographic time-series data may be spatial or nonspatial, single-view or multiple-view, static or dynamic.
Abstract: Strategies for the visual display and analysis of geographic time-series data may be spatial or nonspatial, single-view or multiple-view, static or dynamic. Labels for place names or other geographic metaphors can describe symbols on aspatial time-series charts. Single-static-map strategies incorporate the temporal dimension through techniques ranging from complex point symbols, or temporal glyphs, to generalized trend-surface or flow-linkage maps focusing on movement. The multiple-static-maps strategy juxtaposes two or more maps for a simultaneous visual comparison of time units, whereas the single-dynamic-map strategy either presents maps in a temporal sequence or shows the evolution of a geographic pattern through a temporally sequenced accretion of symbols. In contrast, the multiple-dynamic-maps strategy provides programmed sequences of multiple views or allows the viewer to interact with maps and statistical diagrams representing different instants or periods of time. Electronic graphics systems have...
