Robust light transport algorithms, particularly bidirectional path tracing (BDPT), face significant challenges when dealing with specular or highly glossy involved paths. BDPT constructs the full by connecting sub-paths traced individually from source and camera. However, it remains difficult to sample vertices on surfaces narrow-lobed BSDF, as poses severe constraints sampling in feasible direction. To address this issue, we propose a novel approach, called proxy , that enables efficient...
Bidirectional path tracing (BDPT) can be accelerated by selecting appropriate light sub-paths for connection. However, existing algorithms need to perform frequent distribution reconstruction and have expensive overhead. We present a novel approach, SPCBPT, probabilistic connections that constructs the selection in sub-path space. Our approach bins into multiple subspaces keeps same subspace of low discrepancy, wherein selected subspace-based two-stage sampling method, i.e., first then...
