Abstract
Streaming data to efficiently render complex 3D scenes in presence
of global illumination is still a challenging task. In this paper, we
introduce a new data structure based on a 3D grid of irradiance vectors
to store the indirect illumination appearing on complex and detailed
objects: the Irradiance Vector Grid (IVG). This representation is
independent of the geometric complexity and is suitable for quantization
to different quantization schemes. Moreover, its streaming over network
involves only a small overhead compared to detailed geometry, and can
be achieved independently of the geometry. Furthermore, it can be
efficiently rendered using modern graphics hardware. We demonstrate our
new data structure in a new remote 3D visualization system, that
integrates indirect lighting streaming and progressive transmission of
the geometry, and study the impact of different strategies on data transfer.
