Abstract / Description:In this paper, a novel hybrid algorithm is presented for the fast construction
and high-quality rendering of visual hulls. We combine the strengths of two
complementary hardware-accelerated approaches: direct constructive solid
geometry (CSG) rendering and texture mapping-based visual cone trimming. The
former approach completely eliminates the aliasing artifacts inherent in the
latter, whereas the rapid speed of the latter approach compensates for the
performance deficiency of the former. Additionally, a new view-dependent
texture mapping method is proposed. This method makes efficient use of graphics
hardware to perform per-fragment blending weight computation, which yields
better rendering quality. Our rendering algorithm is integrated in a
distributed system that is capable of acquiring synchronized video streams and
rendering visual hulls in real time or at interactive frame rates from up to
eight reference views.
