Accurate perspective mapping in real-time requires costly division operations per pixel and therefore ap­ proximation techniques are often employed. These per­ mit the mapping to be performed by interpolation, but generally ...

This paper describes a new algorithm and hardware design for the generation of two dimensional images from volume data using the ray casting technique. The algorithm is part of an image generation system that is broken ...

A reflectance map design is described which uses a minimal amount of memory for the table, in order to be applicable as an on-chip shader. The shader is designed for use with the volumetric super resolution hardware, which ...

Mapping textures onto suIfaces of computer-gener­ ated objects is a technique which greatly improves the realism of their appearance. Unfortunately, this imposes high computational demands and, even worse, tremendous memory ...

We discuss the underlying algorithms, design principles and implementation issues of an extremely compact and cost-efficient volume rendering accelerator for PCI-based systems. It operates on classified and shaded data ...

Performance, as measured by the number of primitives rendered per second, has been the most important rendering system design consideration while latency, the amount of time it takes to render an image, has largely been ...

The resolution obtained in volume rendering is greatly increased over known methods through the introduction of super resolution techniques which make it possible to enlarge the view o f the dataset without the introduction ...

In this paper we present our research efforts towards a scalable volume rendering architecture for the real-time visualization of dynamically changing high-resolution datasets. Using a linearly skewed memory interleav­ ing ...
