SUMMARY:Unbiased Differential Visibility Using Fixed-Step Walk-on-Spherica
 l-Caps And Closest Silhouettes
DESCRIPTION:Lifan Wu, Nathan Morrical, Sai Praveen Bangaru, Rohan Sawhney,
  Shuang Zhao, Chris Wyman, Ravi Ramamoorthi, and Aaron Lefohn (NVIDIA)\n\n
 Warped-area reparameterization is a powerful technique to compute differen
 tial visibility. The key is constructing a velocity field that is continuo
 us in the domain interior and agrees with defined velocities on boundaries
 . We present a robust and efficient unbiased estimator for differential vi
 sibility, using a fixed-step walk-on-spheres and closest silhouette querie
