Abstract
We describe the software architecture of the Manta interactive ray tracer and describe its application in engineering and scientific visualization. Although numerous ray tracing software packages have been developed, much of the traditional design wisdom needs to be updated to provide support for interactivity, high degrees of parallelism, and modern packet-based acceleration structures. We discuss situations that are normally not considered when designing a batch ray tracer, and present methods to overcome those challenges. This paper advocates a forward looking programming model for interactive ray tracing that uses reconfigurable components to achieve flexibility while achieving scalability on large numbers of processors. Manta employs data structures motivated by modern micro-processor design that can exploit instruction-level parallelism. We discuss the design tradeoffs and the performance achieved for this system.
