Mesh gradients are a powerful way to create smooth, organic color transitions. Traditional techniques like spline-based interpolation or multiple overlapping radial gradients can be effective—but they also come with trade-offs: visual artifacts, complexity, or the need for structured meshes.
In this article, I’ll show you how to use Radial Basis Function (RBF) interpolation to generate seamless gradients from just a set of colored points. This approach is portable, flexible, and simple to implement.
