Abstract

This paper accelerates the rendering of diffusion curves using the ray tracing cores found on modern NVIDIA graphics cards using the method described by Bowers et al. [Bowers, Leahey and Wang 2011]. This method approximates the final result of the Poisson equation and in this paper is accelerated using Optix and dedicated ray tracing hardware. Using this method yielded a render time decrease of around 8 times between the Quadro P1000 and RTX 2060, while retaining the complex colour gradients and ease of use of traditional diffusion curves solved using the Poisson equation.
