    Stochastic Computation of Barycentric Coordinates Fernando de Goes, Mathieu Desbrun April 2024 This paper presents a practical and general approach for computing barycentric coordinates through stochastic sampling. Our key insight is a reformulation of the kernel integral defining barycentric coordinates into a weighted least-squares minimization that enables Monte Carlo integration without sacrif
