3D Jazzy Starfield Animation

An energetic 3D starfield animation inspired by the vibrant, improvisational spirit of jazz music. Built with HTML5 Canvas and vanilla JavaScript, featuring dynamic colors, pulsing effects, and smooth movements that capture the essence of a jazz performance.

Features

• Jazz-Inspired Colors: Vibrant golds, blues, reds, and whites reminiscent of jazz club lighting
• Dynamic Pulsing: Stars pulse and breathe with jazz-like rhythm and timing
• Improvisation Effects: Random movement variations that add spontaneity to the animation
• Dramatic Glow Effects: Multi-layered glow rendering for stage-light atmosphere
• Sparkle Effects: Larger stars create sparkle effects during peak pulse moments
• 3D Perspective: Stars move through 3D space with realistic depth perception
• Smooth Trails: Subtle trailing effects for fluid motion
• Jazz Club Atmosphere: Dark, moody background with subtle gradients
• Responsive Design: Automatically adjusts to window size changes
• Optimized Performance: Uses requestAnimationFrame for smooth 60fps animation

Jazz-Inspired Elements

• Color Palette: Five distinct color families (Gold, Blue, Red, White, Copper) with natural variations
• Rhythmic Pulsing: Each star has its own pulse timing, creating a polyrhythmic visual effect
• Improvisation: Stars can deviate from their standard paths, adding spontaneity
• Dynamic Sizing: Stars grow and shrink based on their pulse phase
• Atmospheric Rendering: Multi-layer glow effects create depth and warmth

How it Works

• 1200 stars are generated with jazz-inspired colors and properties
• Each star has unique pulse timing and improvisation characteristics
• Stars rotate around the center with slight variations
• Perspective projection creates realistic 3D depth
• Multiple glow layers create rich, dramatic lighting effects
• Stars that move off-screen are recycled with new jazz properties

Usage

Simply open index.html in a web browser. The jazz-inspired animation starts automatically and fills the entire viewport.
