Zusammenfassung:
With the tremendous advances in both hardware capabilities and
rendering algorithms, rendering performance is steadily increasing.
Even consumer graphics hardware can render many million
triangles per second. However, scene complexity seems to be rising
even faster than rendering performance, with no end to even more
complex models in sight.
In this paper, we are targeting the interactive visualization of the
``Boeing 777'' model, a highly complex model of 350 \emph{million}
individual triangles, which -- due to its sheer size and complex
internal structure -- simply cannot be handled satisfactorily by
today's techniques. To render this model, we use a combination of
real-time ray tracing, a low-level out of core caching and demand
loading strategy, and a hierarchical, hybrid
volumetric/lightfield-like approximation scheme for representing
not-yet-loaded geometry.

With this approach, we are able to render the full
777 model at several frames per second even on a single
commodity desktop PC.
