Opened up an AI Studio export called TerraGemini expecting a generic Three.js wrapper and found a 918-line hand-rolled WebGL renderer instead. The entire globe runs on custom GLSL shaders without a single Three.js dependency — separate vertex and fragment programs for dot-matrix land masses, graticule lines, a pulsing location beacon, and a background star field. It pulls 50m TopoJSON data from CDN, rasterizes it onto an offscreen 4096×2048 2D canvas, and runs cosine rejection sampling across the pixel data to generate ~150,000 holographic points with uniform sphere density. There is a built-in momentum physics engine for drag rotation, spring dampening on zoom, and smooth RGB lerping between day mode and amber night mode. The reconnaissance turned up the standard AI Studio detritus — a dead import map pointing to aistudiocdn.com, a missing index.css, and a Vite define block baking PLACEHOLDER_API_KEY straight into the 556KB production bundle. But the core rendering math was pristine, compiling clean across 160 npm packages with zero vulnerabilities.
