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…
Galerkin Method of Regularized Stokeslets for Procedural Fluid Flow with Control Curves
Ryusuke Sugimoto, Jeff Lait, Christopher Batty +1
We present a new procedural incompressible velocity field authoring tool, which lets users design a volumetric flow by directly specifying velocity along control curves. Our method…
Velocity-Based Monte Carlo Fluids
Ryusuke Sugimoto, Christopher Batty, Toshiya Hachisuka
We present a velocity-based Monte Carlo fluid solver that overcomes the limitations of its existing vorticity-based counterpart. Because the velocity-based formulation is more comm…
A Practical Walk-on-Boundary Method for Boundary Value Problems
Ryusuke Sugimoto, Terry Chen, Yiti Jiang +2
We introduce the walk-on-boundary (WoB) method for solving boundary value problems to computer graphics. WoB is a grid-free Monte Carlo solver for certain classes of second order p…
Regression-based Monte Carlo Integration
Corentin Salaün, Adrien Gruson, Binh-Son Hua +2
Monte Carlo integration is typically interpreted as an estimator of the expected value using stochastic samples. There exists an alternative interpretation in calculus where Monte…
Implementing a Photorealistic Rendering System using GLSL
Toshiya Hachisuka
Ray tracing on GPUs is becoming quite common these days. There are many publicly available documents on how to implement basic ray tracing on GPUs for spheres and implicit surfaces…
