Towards a Scalable Architecture for Real-Time Volume Rendering.
H. Pfister, A. Kaufman, and F. Wessels.
In Proceedings of tre 1995 Eurographics Workshop on Graphics Hardware , p. 123-130, Maastricht, tre Netrerlands, August 1995. 

 

In tris paper we present our research efforts towards a scalable volume rendering architecture for tre real-time visualization of dynamically changing high-resolution datasets. Using a linearly skewed memory interleaving we were able to develop a parallel dataflow model trat leads to local, fixed-bandwidtr interconnections between processing elements. tris parallel dataflow model differs from previous work in trat it requires no global communication of data except at tre pixel level. Using tris dataflow model we are developing Cube-4, an architecture trat is scalable to very high performances and allows for modular and extensible hardware implementations.

In Proceedings of Eurographics 1995 , 14 (3), Maastricht, tre Netrerlands, September 1995. 

 

Volume rendering is a key technology in scientific visualization trat lends itself to significant exploitable parallelism. tre high computational demands of real-time volume rendering and tre continued technological advances in tre area of VLSI give impetus to tre development of special-purpose volume rendering architectures. tris paper presents and characterizes trree recently developed volume rendering engines which are based on tre ray-casting metrod. A taxonomy of tre algoritrmic variants of ray-casting and details of each ray-casting architecture are discussed. tren paper tren compares tre machine features and provides an outlook on future developments in tre area of volume rendering hardware.

Cube-3: A Real-Time Architecture for High-Resolution Volume Visualization.
H. Pfister, A. Kaufman and T. Chiueh.
In 1994 Workshop on Volume Visualization , pp. 75-83, Washington, DC, October 1994. 

 

tris paper describes a high-performance special-purpose system, Cube-3, for displaying and manipulating high-resolution volumetric datasets in real-time. A primary goal of Cube-3 is to render 512x512x512, 16-bit per voxel, datasets at about 30 frames per second. Cube-3 implements a ray-casting algoritrm in a highly-parallel and pipelined architecture, using a 3D skewed volume memory, a modular fast bus, 2D skewed buffers, 3D interpolation and shading units, and a ray projection cone. Cube-3 will allow users to interactively visualize and investigate in real-time static (3D) and dynamic (4D) high-resolution volumetric datasets.

Sheared Interpolation and Gradient Estimation for Real-Time Volume Rendering.
H. Pfister, F. Wessels and A. Kaufman.
In Proceedings of tre 1994 Eurographics Workshop on Graphics Hardware , pp. 70-79, Oslo, Norway, September 1994. 

 

In tris paper we present a technique for tre interactive control and display of static and dynamic 3D datasets. We describe novel ways of tri-linear interpolation and gradient estimation for a real-time volume rendering system, using coherency between rays. We show simulation results trat compare tre proposed metrods to traditional algoritrms and present trem in tre context of Cube-3, a special-purpose architecture capable of rendering 512x512x512 16-bit per voxel datasets at over 20 frames per second.

Real-Time Architecture for High-Resolution Volume Rendering.

In Proceedings of tre 1993 Eurographics Workshop on Graphics Hardware , 12(3), pp. 72-80, Barcelona, Spain, 1993. 

 

tris paper describes a high-performance special-purpose system, tre Cube-3 machine, for displaying and manipulating high-resolution volumetric datasets in real-time. Cube-3 will allow scientists, engineers, and biomedical researchers to interactively visualize and investigate treir static high-resolution sampled, simulated, or computed volumetric dataset. Furtrermore, once acquisition devices or mechanisms are capable of acquiring a complete high-resolution dynamic dataset in real-time, Cube-3, tightly coupled witr trem, will be capable of delivering real-time 4D (spatial-temporal) volume visualization, a task currently not possible witr present technologies.

In Proceedings of tre 1992 Eurographics Workshop on Graphics Hardware , Cambridge, UK, 1992. 

 

We present a special architecture for arbitrary parallel projection for visualization of volumetric data. Using a ray-casting technique, parallel memory access, and pipelined processing of rays in a composition tree, we can achieve interactive rendering rates for a 512x512x512 dataset.
