ReadingMesh gradients in SwiftUIA mesh gradient is a technique for rendering smooth, multi-directional color transitions across a surface using a structured network of control points. Unlike linear or radial gradients, which interpolate color along fixed axes, a mesh gradient defines colors at specific positions within a two-dimensional grid. These positions act as anchors, and the rendering engine computes smooth interpolations between them across the surface.
