TL;DR: The Appollo DN10000VS treats graphics as an integral part of the system architecture, and supports alpha buffering, quadratic interpolation, and texture mapping directly in hardware, which reduces the cost of a high-end workstation, without sacrificing high rendering quality and performance.
Abstract: The Appollo DN10000VS treats graphics as an integral part of the system architecture. Graphics requirements influence the entire system design. All floating-point computations for graphics are performed by the CPU(s), while rasterizing is handled by simplified hardware having no microcode. We decided to support alpha buffering, quadratic interpolation, and texture mapping directly in hardware. This partitioning reduces the cost of a high-end workstation, without sacrificing high rendering quality and performance. This paper describes some of the design trade-offs which led to the final system design.

TL;DR: In this paper, a method of rasterizing a graphics basic component (120) in a graphics system is described, where pixel data for the graphics basic element are generated on the basis of data that describe the graphics-basic element.
Abstract: The invention relates to a method of rasterizing a graphics basic component (120) in a graphics system. According to the inventive method, pixel data for the graphics basic element are generated on the basis of data that describe the graphics basic element. The graphics system comprises a memory that is subdivided into a plurality of blocks (a, a+1, b, b+1) that are allocated to an array on an image screen (114) that is predetermined among a plurality of arrays. Every block of the plurality of blocks (a, a+1, b, b+1) is allocated to a memory page of the memory. The method comprises scanning the pixels allocated to the graphics basic element (120) in a plurality of blocks (a) into which the graphics basic element extends, repeating the previous step until all pixels allocated to the graphics basic element are scanned in the plurality of blocks in which the graphics basic element extends, and outputting the pixel data.

TL;DR: This work reports on the implementation of popular reconstruction algorithms as weighted backprojection, simultaneous iterative reconstruction technique (SIRT), SIRT and SART on common graphics processors (GPUs) and shows that the quality of the reconstruction on the GPU is comparable to the CPU.

TL;DR: It is shown how the computational power and programmability of modern graphics processing units (GPUs) can be used to efficiently solve large-scale pixel-based material distribution problems using a gradient-based optimality criterion method.
Abstract: We show how the computational power and programmability of modern graphics processing units (GPUs) can be used to efficiently solve large-scale pixel-based material distribution problems using a gradient-based optimality criterion method. To illustrate the principle, a so-called topology optimization problem that results in a constrained nonlinear programming problem with over 4 million decision variables is solved on a commodity GPU.

TL;DR: In this article, the authors present methods through which designers can use graphics to convey meaning and instruct, the types of outcomes that graphics are particularly adept at facilitating, and the conditions that affect how well they succeed.
Abstract: Publisher Summary This chapter discusses the design and use of instructional graphics. The chapter presents methods through which designers can use graphics to convey meaning and instruct, the types of outcomes that graphics are particularly adept at facilitating, and the conditions that affect how well they succeed. The design of instructional graphics (charts, graphs and diagrams) is carried out by means of a decision-making process that is common to all instructional design. The purpose of design is to select the best instructional method from among many, and to base that selection upon a rational analysis of what the goals to be attained are, and the conditions under which their attainment is to occur. Instructional strategies that use graphics are chosen largely on the basis of the different ways in which different graphic forms convey meaning. Charts, graphs, and diagrams express ideas in a variety of ways, such as concrete concepts, such as the animals in a food chain, can be represented by words, by pictures of varying degrees of realism, or by arbitrary symbols.
