The oldest rule in tech is simple: "Can it run DOOM?" But today, I'm asking a harder question: Can AI CODE it from scratch? I challenged Google's Gemini 3 Pro Ultra and Claude 4.5 Pro Max to write a raw Raycasting engine (Wolfenstein 3D style) in a single HTML file. No , no Unity, no libraries. Just pure Math and JavaScript. 🚀 THE CHALLENGE: Creating 3D walls using 2D code is incredibly hard. The AI needs to calculate angles, distance, and rendering logic instantly. One of these models created a smooth 60 FPS engine. The other... struggled with the math. 📌 TIMESTAMPS: 0:00 - The "Impossible" Doom Challenge 0:50 - The No-Library Prompt (Raycasting) 2:30 - Gemini 3 Pro Attempt (Speed Coding) 5:10 - Claude 4.5 Pro Max Attempt (The Logic) 7:45 - Playing the AI Games: Who Won? 🔥 PROMPT USED: "Code a playable DOOM / Wolfenstein 3D style clone from scratch in a SINGLE HTML file.
