Precomputed Lens Transport Maps
Yang Chen, Xiaochun Tong, Afet Abzar +3
Accurate real-time simulation of lens optics remains challenging due to the computational expense of full ray tracing and the limitations of existing approximations. The commonly u…

Monte Carlo Rendering to Diffusion Curves with Differential BEM
Ryusuke Sugimoto, Christopher Batty, Siddhartha Chaudhuri +4
We present a method for generating vector graphics, in the form of diffusion curves, directly from noisy samples produced by a Monte Carlo renderer. While generating raster images…

Projected Walk on Spheres: A Monte Carlo Closest Point Method for Surface PDEs
Ryusuke Sugimoto, Nathan King, Toshiya Hachisuka +1
We present projected walk on spheres (PWoS), a novel pointwise and discretization-free Monte Carlo solver for surface PDEs with Dirichlet boundaries, as a generalization of the wal…
