🎨 Graphics Features Explained

1. Procedural Textures

Instead of solid colors, the game generates realistic textures:

• Grass - Thousands of individual grass blades
• Asphalt - Grainy road surface with markings
• Buildings - Brick patterns with lit/dark windows
• Metal - Brushed metal effect for car paint
• Tire - Rubber tread patterns

2. PBR Materials (Physically Based Rendering)

Materials react to light realistically:

• Metalness - How metallic a surface is
• Roughness - How rough/smooth a surface is
• Emissive - Self-illuminating parts (lights, windows)
• Transmission - Glass transparency

3. Lighting System

• Sun - Directional light with soft shadows
• Ambient - Fill light from sky
• Hemisphere - Sky/ground gradient lighting
• Point Lights - Street lamps and decorative lights
• Spot Lights - Vehicle headlights

4. Shadows

• PCF Soft Shadows - Smooth, realistic shadows
• 4096x4096 Shadow Map - High resolution
• Dynamic - Move with sun and objects

5. Particle Effects

• Muzzle Flash - Yellow sparks when shooting
• Impact - Red sparks when hitting targets
• Explosions - Orange/red particle bursts
• Additive Blending - Glow effect

6. Environment Details

• Trees - Multiple spheres for realistic foliage
• Street Lights - Light poles with glowing lamps
• Buildings - AC units on roofs, window details
• Roads - Proper asphalt texture with lane markings

7. Vehicle Details

• Headlights - Working beams (toggle with L)
• Taillights - Red glowing rear lights
• Glass Windows - Transparent materials
• Wheels - Tires with tread + metal rims
• Paint - Shiny metallic finish

8. Character Animation

• Walking - Legs and arms swing naturally
• Running - Faster animation when sprinting
• Idle - Return to standing position

📊 Technical Improvements

Rendering

• Antialiasing - Smooth edges
• Tone Mapping - ACES Filmic for cinematic look
• sRGB Encoding - Correct color space
• High DPI - Sharp on 4K displays
• Soft Shadows - PCF filtering

Performance

• Optimized Geometry - Efficient meshes
• Material Caching - Reuse materials
• Texture Atlasing - Fewer draw calls
• Distance Culling - Fog limits draw distance
• Level of Detail - Simplified distant objects

🏗️ Architecture

Material System

// PBR-like material
new THREE.MeshStandardMaterial({
    color: 0xcc0000,      // Base color
    roughness: 0.2,       // Shiny

});

Texture Generation

// Procedural canvas textures
const canvas = document.createElement('canvas');
// Draw grass, asphalt, bricks, etc.
const texture = new THREE.CanvasTexture(canvas);

Particle System

// GPU-accelerated particles
const geometry = new THREE.BufferGeometry();
const positions = [];
const velocities = [];
// Update in animation loop

🔧 Customization

Graphics Settings (in game.js)

const CONFIG = {
    SHADOW_MAP_SIZE: 4096,     // Shadow quality (2048, 4096, 8192)
    ENABLE_SHADOWS: true,       // Toggle shadows
    ENABLE_PARTICLES: true,     // Toggle particles
    ENABLE_FOG: true,          // Toggle fog

};

Performance Tips

If FPS is low:

1. Decrease SHADOW_MAP_SIZE to 2048
2. Set ENABLE_SHADOWS to false
3. Reduce MAX_PEDESTRIANS to 10
4. Reduce MAX_VEHICLES to 6
5. Decrease DRAW_DISTANCE to 300
