ChatGPT Version Prompt: Role: Expert Three.js Developer & Mechanical Engineer. Task: Create a single-file HTML application simulating a hyper-realistic Cross-Plane V8 Engine for educational purposes. Core Mechanical Specs: Configuration: 90° V8 layout. Crankshaft: Cross-plane design with throws at 0°, 90°, 270°, 180°. Use complex ExtrudeGeometry for the crank webs (counterweights) to look like cast iron, not simple boxes. Firing Order: GM Standard 1-8-4-3-6-5-7-2. Bank Offset: The Right Cylinder Bank must be physically staggered (offset along Z-axis) by exactly one connecting rod width relative to the Left Bank so rods share crank pins side-by-side without clipping. Visual Assets & Materials (PBR): Pistons: High-poly CylinderGeometry with 3 visible chrome rings and a wrist pin hole. Material: Bright Aluminum (Roughness 0.3, Metalness 0.6). Connecting Rods: H-Beam style, Forged Steel material (Metalness 0.8), detailed with big-end caps and bolts. Cylinder Heads: Detailed circular aluminum heads with valve covers, spark plugs (ceramic metal), and 6-bolt patterns. Cylinders: Transparent Glass (MeshPhysicalMaterial, transmission 0.98, opacity 0.12) constrained strictly between the cylinder head and the bottom of the stroke. Add a dark metal base ring at the bottom. Combustion Gas: A dynamic cylinder mesh inside the glass that scales from the piston top to the cylinder head. Lighting: High-contrast studio lighting. Use a DirectionalLight with high-res shadows (4096 map) to simulate sunlight, plus Rim lights and Fill lights. Animation & Physics Logic (The Critical Part): Kinematics: Use exact Slider-Crank formulas based on CrankRadius and RodLength to calculate Piston Y position. Global Synchronization: Calculate a global CycleAngle (0°-720°) for each cylinder based on the global crank rotation, bank angle offset, and the specific Firing Order delay. Valve Timing (Trapezoidal): Intake Valve: Opens exactly at 0° (TDC), closes exactly at 180° (BDC). Use a steep opening curve (not a slow sine wave). Exhaust Valve: Opens exactly at 540° (BDC), closes exactly at 720° (TDC). Strict Separation: Ensure Intake and Exhaust never overlap visually. 4-Stroke Color Logic: Intake (0-180): Transparent fading to Blue (Air filling). Compression (180-360): Blue fading to Orange (Pressure building). Power (360-540): Trigger bright White Flash (Bloom) at 360° (TDC), fading to Red and then Dark Red as piston descends. Exhaust (540-720): Maintain the Dark Red/Grey color (do not clear it) and keep high opacity to show waste gas being pushed out. Rendering & Post-Processing: Use EffectComposer with UnrealBloomPass. Bloom Settings: Threshold 0.8 (only fire glows), Strength 1.8, Radius 0.5. Tone Mapping: ACESFilmicToneMapping with exposure 0.7 to prevent metal blowout while keeping the explosion bright. UI & Architecture: Library: Three.js (CDN). Control Panel (lil-gui): RPM Slider: Default to 50 RPM (Slow motion for education). Range 0-6000. Exploded View: Slider to expand banks outward. Opacity: Slider for cylinder glass. Code Structure: Use ES6 Classes (Crankshaft, PistonAssembly, CylinderHead, EngineSimulation). Constraint: Ensure the animation loop calculates dt correctly so physics are frame-rate independent. Output: A single, runnable HTML file containing all CSS, JS, and logic. No external assets (textures/models) allowed; use procedural geometry.

Updated my #engineSimulation. Now, apart from speed and RPM, I added some basic switching to test kickstand, neutral, and clutch switches. Also added a help menu with a list of basic commands. Coming soon to GitHub github.com/CircuitWorks1/EBR… #canbus #ebr1190 #carhacking
