Advanced Techniques

Explore advanced creative coding techniques using P5 Svelte. These examples demonstrate complex rendering techniques, optimization strategies, and integration with Svelte's reactive system.

Pixel Manipulation

Shader-like Effects

Direct pixel manipulation creating shader-like effects:

View Code

const shaderSketch: Sketch = {
  setup: (p5) => {
    p5._time = 0;
  },
  draw: (p5) => {
    p5.loadPixels();
    // Pixel manipulation logic...
    p5.updatePixels();
  }
};

Performance Optimization

Memory Management

// Object pooling example
class ParticlePool {
  constructor(size) {
    this.pool = new Array(size)
      .fill(null)
      .map(() => new Particle());
  }

  get() {
    return this.pool.find(p => !p.active);
  }
}

WebGL Integration

const sketch: Sketch = {
  setup: (p5) => {
    let shader = p5.createShader(vertSrc, fragSrc);
    p5.shader(shader);
  }
};

Worker Threads

// Web Worker example
const worker = new Worker('compute.js');
worker.postMessage({ data });
worker.onmessage = (e) => {
  // Handle computed results
};

Integration Patterns

Advanced Integration Tips:

Use custom events for complex interactions
Implement proper cleanup in onDestroy
Leverage Svelte's reactive statements
Handle WebGL context loss and restoration
