要旨:
We present a novel algorithm for simultaneous visual hull reconstruction and
rendering by exploiting off-the-shelf graphics hardware. The reconstruction is
accomplished by projective texture mapping in conjunction with alpha test.
Parallel to the reconstruction, rendering is also carried out in the graphics
pipeline. We texture the visual hull view-dependently with the aid of fragment
shaders, such as nVIDIA's register combiners. Both reconstruction and rendering
are done in a single rendering pass. We achieve frame rates of more than 80 fps
on a standard PC equipped with a commodity graphics card. The performance is
significantly faster than previously reported performances of similar systems.
