In traditional CAD and solid modeling, 3D objects are represented in terms of their geometric components. In contrast, in volume graphics 3D objects are represented by a discrete digital model, which is stored as a large 3D array of unit volume elements (voxels).

A graphical model consists of I a graph G = (V,E) and a V set of properties that determine a family of V probability distributions. There are many different types of graphs and properties, each determining a family. It is common to be able to develop algorithms that work for all members of the family by considering only a graph and its properties. Thus,

AbstractA class of log‐linear models, referred to as labelled graphical models (LGMs), is introduced for multinomial distributions. These models generalize graphical models (GMs) by employing partial conditional independence restrictions which are valid only in subsets of an outcome space.

International Joint Conference on Autonomous Agents and Multiagent Systems, 2011
I introduce a graphical representation for modeling multiagent systems based on different kinds of reasoning about agent behavior. I seek to investigate this graphical model's predictive and representative capabilities across various domains, and examine methods for learning the graphical structure from agent interaction data. I also propose to explore

Abstract This book provides the basic mathematical and statistical theory of graphical models, incorporating some of the many advances that have been made since the appearance of the first edition. It contains the basic graph theory, the fundamentals of conditional independence both for probabilistic conditional independence and in ...

A model for graphical interaction
Software Engineering Journal, 1988Much attention has been paid recently to graphics packages which provide standard mechanisms for graphical output in a device-independent way. These packages usually attempt to model a repertoire of input tools in a similarly abstract way. While implementing the Graphical Kernel System (GKS) it was observed that the model for handling interactive input

A database design for graphical models
ACM SIGPLAN Notices, 1990In this paper we present an engineering data management system, that is a database which is supposed to store and support the manipulation of data about solid geometry objects. Some technical aspects are particularly addressed, which are related to the modeling environment, system architecture and data manipulation language.

Interactive Graphics for Volume Modeling
18th Design Automation Conference, 1981This paper describes the GRaphic INput subsystem (GRIN) of an experimental volume modeling system called the Geometric Design Processor (GDP) developed at the IBM Thomas J. Watson Research Center. Sitting at an interactive graphic workstation, a mechanical designer generates computer volume models of complex physical objects and mechanisms built up ...

Mathematical Models of Graphics
Computer Graphics and Image Processing, 1980Publisher Summary This chapter reviews some mathematical models for graphics as data sources and the interplay between these models and coding schemes. Graphics include the following three classes of images: (1) images that are nominally two tone, (2) binary images derived from continuous-tone images, (3) and binary images created in some continuous ...

A reflectance model for computer graphics
Proceedings of the 8th annual conference on Computer graphics and interactive techniques - SIGGRAPH '81, 1981This paper presents a new reflectance model for rendering computer synthesized images. The model accounts for the relative brightness of different materials and light sources in the same scene. It describes the directional distribution of the reflected light and a color shift that occurs as the reflectance changes with incidence angle.
