This article explores various techniques—from CSS animation to WebGL shaders—for rendering rain in a browser, analyzes the underlying algorithms, provides GLSL and Three.js code examples, and discusses performance optimizations and extensions such as snow effects.
This tutorial demonstrates how to create a realistic rain effect in three.js by generating depth maps with an orthographic camera, rendering them to a texture, and using custom shaders to position and fade raindrop meshes based on depth information.
This article explains how to create a realistic, map‑based rain effect with Three.js by designing a 3D particle system, writing custom vertex and fragment shaders, integrating the layer into a map scene, and extending it to support wind and snow effects.
This article walks through building a reusable canvas‑based drop component that renders realistic rain and snow animations, explains the underlying JavaScript architecture, and provides complete source code with usage examples and future enhancement ideas.
