Multi-Rocket Launch Complex: Added three identical rockets arranged realistically around the launchpad, maintaining consistent takeoff animations and launch pad platforms.Cinematic Camera Improvements:Implemented smooth mouse-wheel zooming during the flight sequence.Added camera bounds constraints to ensure the camera never clips below the grey launchpad platforms.Rendered clear instructions on-screen in red text: “Mouse Wheel: Zoom In/Out During Launch”.Integrated Pre-Launch Screen: Updated the pre-launch scene and hangar environments to show all three rockets in their formation.2. Performance Engineering & Optimization (Target: 120 FPS)Particle Recycling Pool: Implemented a global recycling pool for engine flares, smoke, and sparks to eliminate frame-rate stutters caused by CPU/GPU memory allocations.Resolved WebGL Resource Leaks: Ensured proper disposal of geometries and materials on scene transitions/cleanup, preventing WebGL context losses.Render Pipeline Tuning: Set depthWrite: false on smoke/fire transparent materials to bypass depth buffer sorting bottleneck, and integrated dynamic frustum/distance culling to skip rendering objects far behind the camera.React Rendering Optimization: Memoized all primary UI screen components (MainMenu, HangarScreen, PilotLog, ProfileScreen) using React.memo to eliminate cascading re-renders from telemetry updates.3. Real-Time Diagnostics & TestingPerformance HUD Overlay: Built a real-time developer diagnostics panel showing FPS, frame render times, draw calls, triangle counts, active particles, and active WebGL geometries/textures.Automated Integration Testing: Successfully verified the changes with production builds and playwright headless-WebGL simulation scripts (node scripts/_probe-launch.mjs), confirming all telemetry flows, camera cycles, and abort-to-result sequences pass with zero runtime errors.
