A step-by-step guide to creating an animated smoke effect using Three.js shader materials. Covers setting up a scene with custom vertex and fragment shaders, applying Perlin noise textures, creating transparency masks, animating texture movement, remapping color values for realistic smoke appearance, fading edges with smoothstep, and twisting geometry around the y-axis for a 3D spiral effect. Includes code examples for UV mapping, texture sampling, depth writing configuration, and 2D rotation functions.
