    "prompt": "<!-- SC_OFF --><div class=\"md\"><p>I ran a side-by-side coding benchmark to see how Opus 5.5, Opus 5, GPT-6 Astra, and GPT-6 Sol handle complex 3D state machines, procedural geometry, and live telemetry UI from a single specification.</p> <p><a href=\" <p>Prompt:<br/> Write a complete, single-file HTML/JavaScript application that simulates a SpaceX Falcon 9 (Starlink mission) rocket launch in 3D using the library. The application must run locally in a web browser without requiring a build step by loading via CDN.<br/> Push your rendering and mathematical capabilities to the limit by satisfying the following requirements:</p> <ol> <li>Procedural Rocket Geometry: Generate a detailed Falcon 9 rocket using primitives (cylinders, cones, boxes). Include the main booster, folded landing legs, grid fins, the black interstage, second stage, and the distinct blunt Starlink payload fairing.</li> <li>Launch Environment: Build a launch pad featuring a strongback support structure, a textured concrete ground plane, and a dynamic atmospheric gradient for the sky.</li> <li>Physics-Based Animation: Program a realistic launch sequence. The rocket must start stationary, ignite with a 2-second hold, release clamps, and accelerate upward using a continuous physics calculation (accounting for thrust, mass, gravity, and acceleration).</li> <li>Custom Particle System: Implement a high-performance, custom particle system for the engine exhaust plume and pad smoke. The particles must feature dynamic scaling, velocity, opacity fading, and color interpolation (from bright white/yellow ignition to expanding gray smoke).</li> <li>Cinematic Camera: Program a dynamic camera system that starts low on the pad, tracks the rocket as it ascends, and includes procedural &quot;camera shake&quot; that scales in intensity with engine thrust and simulated dynamic pressure (Max-Q).</li> <li>Dynamic Lighting: Implement directional daylight and ambient lighting with realistic shadows. Attach a flickering, intense point light to the engine exhaust to cast dynamic shadows from the rocket onto the launch pad structure during liftoff.</li> </ol> <p>Ensure the code is robustly structured, highly optimized for smooth framerates</p> </div><!-- SC_ON --> &; submitted by &; <a href=\" /u/davchi1 </a> <br/> <span><a href=\" &; <span><a href=\"",
