System Architecture

Core Components

1. Visualization Engine

// Note: Simplified implementation example
import * as THREE from 'three';

class VisualizationEngine {
  scene: THREE.Scene;
  camera: THREE.PerspectiveCamera;
  renderer: THREE.WebGLRenderer;

  constructor(container: HTMLElement) {
    this.scene = new THREE.Scene();
    this.camera = new THREE.PerspectiveCamera(75, container.clientWidth / container.clientHeight, 0.1, 1000);
    this.renderer = new THREE.WebGLRenderer();
    this.renderer.setSize(container.clientWidth, container.clientHeight);
    container.appendChild(this.renderer.domElement);
  }

  render() {
    requestAnimationFrame(() => this.render());
    this.renderer.render(this.scene, this.camera);
  }

  addObject(object: THREE.Object3D) {
    this.scene.add(object);
  }

  removeObject(object: THREE.Object3D) {
    this.scene.remove(object);
  }
}

2. Algorithm Controller

// Note: Simplified implementation example
class AlgorithmController {
  private steps: Array<() => void>;
  private currentStep: number;

  constructor(steps: Array<() => void>) {
    this.steps = steps;
    this.currentStep = 0;
  }

  nextStep() {
    if (this.currentStep < this.steps.length) {
      this.steps[this.currentStep]();
      this.currentStep++;
    }
  }

  reset() {
    this.currentStep = 0;
  }
}

3. Complexity Analyzer

// Note: Simplified implementation example
class ComplexityAnalyzer {
  analyzeTimeComplexity(algorithm: string): string {
    const complexities: { [key: string]: string } = {
      'Bubble Sort': 'O(n^2)',
      'Quick Sort': 'O(n log n)',
      'Binary Search': 'O(log n)',
      // Add more algorithms as needed
    };
    return complexities[algorithm] || 'Unknown';
  }

  analyzeSpaceComplexity(algorithm: string): string {
    const complexities: { [key: string]: string } = {
      'Bubble Sort': 'O(1)',
      'Quick Sort': 'O(log n)',
      'Binary Search': 'O(1)',
      // Add more algorithms as needed
    };
    return complexities[algorithm] || 'Unknown';
  }
}

Data Flow Architecture

User Interaction
- Users select an algorithm and input parameters through the user interface.
Algorithm Execution
- The Algorithm Controller manages the execution steps, allowing users to navigate through each step.
Visualization Rendering
- The Visualization Engine updates the graphical representation based on the current step of the algorithm.
Complexity Analysis
- The Complexity Analyzer provides real-time insights into the algorithm's time and space complexities.
User Feedback
- Users receive immediate visual and analytical feedback, enhancing their understanding of the algorithm's behavior.

Technical Implementation

Building the Visualization Engine

The visualization engine is built using Three.js, a powerful JavaScript library for creating 3D graphics. It renders objects representing data structures and algorithm states in real-time.

import * as THREE from 'three';

class VisualizationEngine {
  // Initialization code as shown above
}

Developing the Algorithm Controller

The Algorithm Controller orchestrates the step-by-step execution of algorithms, allowing users to control the pace and understand each operation's impact.

class AlgorithmController {
  // Implementation as shown above
}

Implementing the Complexity Analyzer

The Complexity Analyzer provides educational insights into the efficiency of algorithms, helping users grasp the theoretical aspects alongside practical visualization.

class ComplexityAnalyzer {
  // Implementation as shown above
}

Integrating with TypeScript and WebGL

Using TypeScript ensures type safety and scalability, while WebGL powers the high-performance rendering necessary for smooth visualizations.

// Example of initializing the Visualization Engine
const container = document.getElementById('visualization-container')!;
const engine = new VisualizationEngine(container);
engine.render();

Operational Characteristics

Monitoring and Metrics

Continuous monitoring ensures the platform operates smoothly, tracking metrics such as frame rate, step execution latency, and user interactions.

class MetricsCollector {
  executionTime: number = 0;
  frameRate: number = 60;

  recordExecutionTime(duration: number) {
    this.executionTime += duration;
  }

  updateFrameRate(fps: number) {
    this.frameRate = fps;
  }

  report() {
    console.log(`Total Execution Time: ${this.executionTime} ms`);
    console.log(`Current Frame Rate: ${this.frameRate} FPS`);
  }
}

Failure Recovery

Although built primarily for simulation and learning, the platform includes basic failure recovery mechanisms to handle unexpected issues gracefully.

Automatic Reset: Resets the algorithm execution if an error occurs during a step.
State Backup: Saves the current state to prevent loss during unexpected interruptions.
Health Checks: Continuously monitors system components to ensure they are functioning correctly.
