WebGL Shader Iridescent (2023)

WebGL shader art distills GPU mathematics into pure visual experience. Born from the demoscene tradition and crystallized by Shadertoy's 2013 launch, this aesthetic renders signed-distance-function geometry on pitch-black canvases, wrapping forms in oil-slick iridescence derived from Fresnel equations.

The 2023 renaissance — fueled by Spline, Three.js maturity, and shader-graph tooling — brought fragment-shader visuals to mainstream web portfolios. The look is unmistakable: saturated violet-cyan-pink bloom against void-black, monospace code overlays, and mathematical primitives that feel alive.

WebGL着色器艺术将GPU数学运算提炼为纯粹的视觉体验。它继承了1990年代Amiga演示场景的精神，在2013年Shadertoy平台上线后正式成型——在纯黑画布上渲染有符号距离函数几何体，用基于菲涅尔方程的油膜虹彩包裹形体。

2023年的复兴浪潮由Spline、Three.js成熟生态和着色器图形工具共同推动，将片段着色器视觉带入主流网页作品集。其标志性外观不可误认：饱和的紫-青-粉光晕在虚空黑底上绽放，等宽字体代码叠加，数学原始体仿佛拥有生命。
