Abstract
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.
