The feasibility of employing the transform coding technique in the compression of binary pictorial data is investigated. Typical linear transformations are reviewed and a hybrid tree-transform coding method is introduced, which promises to perform better than the simple transform scheme for graphic images. Simulation results from the processing of five different graphic image samples on the image-100 system strongly suggests, however, the impracticability of using linear transformations in the coding of graphic images.

A presentation is made of the design for a machine which can rapidly generate realistic continuous-tone color video images of three-dimensional objects from a polygonal data base. The design consists of an array of identical custom LSI chips which form a pixel-mapped image buffer enhanced with certain processing capabilities. Visibility calculations are performed concurrently for all pixels using a depth buffer algorithm, and for a p-sided polygon, 0(p) processing steps are required. The same circuitry which performs visibility calculations also carries out polygon edge definition and smooth shading, and requires only a small part of each pixel's memory area on the chip.

DI-3000 is a machine-independent system of FORTRAN-callable subroutines based on the 1979 'CORE' report of the graphics Standards Planning Committee (GSPC) of ACM/***-3000 supports Output Level-3 (dynamic output), Input Level-2 (synchronous input), and Dimension Level-2 (3D) of the CORE. This includes the complete support of 2D and 3D primitives, full 3D viewing definitions, multiple concurrent display surfaces, Hershey text fonts, all logical input functions, and image transformations. The raster extensions defined in the 1979 CORE Report are also supported, including polygonal primitives, shaded or patterned polygons, and dynamic definition of color video lookup tables on raster ***-3000 uses a network of several interconnected virtual graphics devices which communicate with each other via messages. These virtual devices may represent physical graphics devices, graphics metafiles, or device-independent display files for storing retained *** DI-3000 logical network may be implemented in various ways, depending on the architecture and operating system of the target computer system. The network concept is ideally suited to multi-tasking or distributed processing environments, where either the central memory of the host computer is limited or the target graphics devices have local intelligence. Using a logical network, the virtual graphics devices can execute concurrently for increased *** virtual devices have a distinct layer structure. This allows easy maintenance and extension of the system as the graphics standard evolves, without changes in the basic design. The layer structure also makes it easy to build new graphics device drivers.
Presented is the design of a flexible expandable multi-processor system for video graphics and imageprocessing. The design involves a central controller which broadcasts data to a variable number of independently exe...

This, the 20th issue of the Transactions on Computational Science journal, edited by Bahman Kalantari, is devoted to the topic of Voronoi Diagrams and their applications. The 10 full papers included in the volume are revised and extended versions of a selection of papers presented at the International symposium on Voronoi Diagrams 2012, held in Rutgers, NJ, USA, in June 2012. They provide an in-depth overview of current research on topological data structures and a comprehensive evaluation of their applications in the fields of cartography, physics, material modeling, chemistry, GIS, motion planning and computergraphics.
