Create a stunning wind map using WebGL

  • How I built a wind map with WebGL

    The author presents a WebGL-based wind power simulation demo and discusses the process of overcoming their fear of OpenGL/WebGL programming. They explain the limitations of existing wind visualizations using the Canvas 2D API and propose a solution to implement the simulation logic on the GPU using WebGL. The author describes how to obtain wind data, store particle positions on the GPU, and draw particles using triangles and points. They also cover topics such as drawing particle trails, interpolating wind data, and implementing a pseudo-random generator on the GPU. The result is a fast and visually appealing wind visualization capable of rendering a million particles. The author plans to integrate this into a live map in the future.
