| Abstract: |
In this paper we describe an interactive visualization pipeline for a large-scale simulation
that models the cosmic reionization with yet unmatched spatial resolution. Our
approach is tailored to the massively parallel streaming architectures of modern
graphics hardware. We employ an adaptive raycasting approach to process the large amount of
data that results from the high spatial resolution of 20483 computational cells. The numerical model
allows us to compute the temporal evolution of the ionized regions locally on the GPU while
performing the raycasting, efficiently amortizing the latency of texture memory lookups and minimizing
data transfer from host to GPU memory. |
