We propose PaTraCo (Parallel Transparent Computation), a framework for developing parallel applications for single host or ad-hoc compute network environments incorporating a multitude of different kinds of compute devices ...

Radix-k was introduced in 2009 as a configurable image compositing algorithm. The ability to tune it by selecting k-values allows it to benefit more from pixel reduction and compression optimizations than its predecessors. ...

A method designed for fast isosurfacing on Cell platforms is introduced. It well-utilizes limited amounts of local memory by exploiting a block-based span space. Exploitation goes beyond the usual steps of avoiding span ...

This paper proposes to revisit isosurface extraction algorithms taking into consideration two specific aspects of recent multicore architectures: their intrinsic parallelism associated with the presence of multiple computing ...

The complexity of polygonal models still grows faster than the ability of the graphics hardware to render them in real-time. A common way to deal with such models is to use multiple levels of detail (LODs). These can be ...

In this paper we present an approach to efficiently trace single rays on the Cell Processor, instead of using ray packets. To benefit from the performance of this processor, a data structure is chosen which allows traversal ...

In the field of parallel volume rendering, occlusion is a concept which is already widely exploited in order to improve performance. However, when one moves to larger datasets the use of parallelism becomes a necessity, ...

This work studies the performance and scalability characteristics of hybrid parallel programming and execution as applied to raycasting volume rendering a staple visualization algorithm on a large, multi-core platform. ...
