VIRIM, a real-time direct volume rendering system is evaluated for medical applications. Experiences concerning the hardware architecture are discussed. The issues are the flexibility of VIRIM, the restriction to two ...

The amount of energy consumed in basic CMOS building blocks, like external RAM, external bus-structures, multipliers, local (cache) memory and on chip bus-structures, is analyzed thoroughly to find ways for substantial ...

Integrating the slope and setup calculationsfor triangles to the rasterizer offloads the host processor from intensive calculations and can significantly increase 3D system performance. The processing on the host is greatly ...

Designers of computer graphics hardware have used increasing device counts available from IC manufacturers to increase parallelism using techniques such as putting a longer pipeline of data path elements on integrated ...

The computational power required for direct volume rendering like ray-casting or volume ray-tracing can be provided by high­ speed rendering architectures. However the increasing proces­ sor speed makes a performance ...

We present two implementations of the Cube-4 volume rendering architecture on the Teramac custom computing machine. Cube-4 uses a slice­ parallel ray-casting algorithm that allows for a paral­ lel and pipelined implementation ...

A theory about the energy consumption of algorithms realized in CMOS, presented in related work, makes it possible to calculate the minimal amount of energy dissipated for the execution of an algorithm. The rendering of a ...

Latency contributes to image error and to motion sickness in head­ tracked graphics displays. We attack the problem of latency by exploiting parallel scene generation, using multiple graphics engines to render images ...

This paper describes the Junctionality oj a 3D Graphics Raster Processor called TAYRA. TAYRA consists in the most part oj Graphics Raster Pipeline with five major external interfaces: PCI Master/Target, Depth, Texture, ...
