        this.ctx = this.canvas.getContext('2d');

        });

    render() {
        // Complex rendering logic
    }
}

// Initialize simulation
const mySim = new CameraSim();
mySim.simulateFrame();

Step-by-Step Tutorial

1

Base Structure & Setup

Create the HTML structure with canvas element and basic styling. Add camera controls:


<div class="camera-container">
    <video class="webcam"></video>
    <input type="range" class="brightness-control" min="0" max="100">
    <canvas class="sim-output"></canvas>
</div>

(Optional: Add dark mode toggle with Tailwind variants)

2

Camera Access & Simulation

Use getUserMedia to access fake camera data:


// Demo with simulated camera
const startCamera = async () => {
    try {
        // Fallback to simulated stream
        const simulatedStream = new MediaStream();
        const track = createFakeVideoTrack();
        simulatedStream.addTrack(track);
        
        webcam.srcObject = simulatedStream;
        webcam.play();
    } catch (err) {
        // Error fallback display
    }
};

3D Simulation Logic

Implement perspective transformations and depth simulation:


function simulate3DFrame(frameData) {
    const simulatedDepth = calculateDepth(frameData);
    // Apply perspective distortion based on simulated depth
    return apply3DTransform(frameData, simulatedDepth);
}
