SUMMARY:Unbiased Caustics Rendering Guided by Representative Specular Path
 s
DESCRIPTION:Technical Communications, Technical Papers\n\nUnbiased Caustic
 s Rendering Guided by Representative Specular Paths\n\nLi, Wang, Tu, Xu, H
 olzschuch...\n\nCaustics are interesting patterns caused by the light bein
 g focused when reflecting off glossy materials. Rendering them in Computer
  Graphics is still challenging: they correspond to high luminous intensity
  focused over a small area. Finding the paths that contribute to this smal
 l area is difficult, and even more difficult when using camera-based path 
 tracing instead of bidirectional approaches. Recent improvements in path g
 uiding are still unable to compute efficiently the light paths that contri
 bute to a caustic. In this paper, we present a novel path guiding approach
  to enable reliable rendering of caustics. Our approach relies on computin
 g representative specular paths, then extending them using a chain of sphe
 rical Gaussians. We use these extended paths to estimate the incident radi
 ance distribution and guide path tracing. We combine this approach with se
 veral practical strategies, such as spatial reusing and parallax-aware rep
 resentation for arbitrarily curved reflectors. Our path-guided algorithm u
 sing extended specular paths outperforms current state-of-the-art methods 
 and handles multiple bounces of light and a variety of scenes.\n\nRegistra
