Euro-Spiral Visual Rendering Core – A Real-Time 2D AI Pulse in Motion

Experience the dynamic heartbeat of code — a live JavaScript-rendered spiral powered by trigonometric motion and vibrant HSL color cycling. This canvas-based engine runs entirely in-browser, generating 200+ orbiting points that mimic neural pulse movements.

Core Implementation

Below is the full code of the spiral visualization engine. You can copy, tweak, or remix it:

const canvas = document.createElement("canvas");
                canvas.width = window.innerWidth;
                canvas.height = window.innerHeight;
                document.body.appendChild(canvas);
                const ctx = canvas.getContext("2d");
                
                let t = 0;
                function draw() {
                  ctx.clearRect(0, 0, canvas.width, canvas.height);
                  for (let i = 0; i < 200; i++) {
                    const angle = i * 0.2 + t;
                    const radius = i * 0.5;
                    const x = canvas.width / 2 + Math.cos(angle) * radius;
                    const y = canvas.height / 2 + Math.sin(angle) * radius;
                    ctx.beginPath();
                    ctx.arc(x, y, 3, 0, 2 * Math.PI);
                    ctx.fillStyle = `hsl(${angle * 50}, 100%, 60%)`;
                    ctx.fill();
                  }
                  t += 0.02;
                  requestAnimationFrame(draw);
                }
                draw();

How It Works

1. Canvas Setup: Dynamically adds a full-window canvas element to render the spiral.
2. Trigonometry in Action: Each point's X and Y position is calculated using Math.cos and Math.sin.
3. Color Gradient: Uses HSL for smooth color transitions as each point orbits.
4. Animation Frame Loop: The spiral moves smoothly using requestAnimationFrame.

Why This Feature Matters

• Educational Visual: Perfect for visual learners understanding real-time motion and math in code.
• Creative Displays: Add it to your site header or background as a live visual flair.
• Performance-Oriented: Runs without frameworks and fully GPU-accelerated via the canvas API.
• Modular: Easily customizable for particle count, speed, and design tweaks.
