Abstract :
Global circulation models are used to gain an understanding of the processes that affect the Earth´s climate and may ultimately be used to assess the impact of humanity´s activities on it. The POP ocean model developed at Los Alamos is an example of such a global circulation model that is being used to investigate the role of the ocean in the climate system. Data output from POP has traditionally been visualized using video technology which precludes rapid modification of visualization parameters and techniques. This paper describes a visualization system that leverages high speed graphics hardware, specifically texture mapping hardware, to accelerate data exploration to interactive rates. We describe the design of the system, the specific hardware features used, and provide examples of its use. The system is capable of viewing ocean circulation simulation results at up to 60 frames per second while loading texture memory at approximately 72 million texels per second.
