🎭 Implementation: Core Functionality Explained 🔍

How Does the 3D Effect Work? 🌀

SVG3DTagCloud creates the illusion of 3D movement using simple mathematical transformations. Each tag is positioned in 3D space and rotated dynamically based on user interaction. The key mechanics include:

🌐 Spherical Coordinate System: Each tag is assigned a coordinate on an imaginary sphere.
🔄 Rotation Calculation: The library applies trigonometric functions (sine & cosine) to smoothly rotate the sphere.
🔍 Perspective Scaling: Tags farther from the viewer appear smaller, simulating depth.
🎯 Mouse Interaction: Moving the mouse changes the sphere’s rotation speed, making it feel interactive.

Step 1: Setting Up the 3D Space 🌍

const setChildPosition = (child, radius) => {
  const { x, y, z } = child.vectorPosition;
  const distance = Math.sqrt(x * x + y * y + z * z);
  child.vectorPosition.x = (x / distance) * radius;
  child.vectorPosition.y = (y / distance) * radius;
  child.vectorPosition.z = (z / distance) * radius;
};

This function normalizes each tag’s position onto a spherical surface.

Step 2: Applying Rotation on Mouse Move 🖱️

const updateRotation = (angleX, angleY) => {
  const sinX = Math.sin(angleX);
  const cosX = Math.cos(angleX);
  const sinY = Math.sin(angleY);
  const cosY = Math.cos(angleY);

  tags.forEach((tag) => {
    const { x, y, z } = tag.vectorPosition;
    const tempX = cosY * x - sinY * z;
    const tempZ = sinY * x + cosY * z;
    tag.vectorPosition.x = cosX * tempX + sinX * y;
    tag.vectorPosition.y = -sinX * tempX + cosX * y;
    tag.vectorPosition.z = tempZ;
  });
};

This applies 2D rotation matrices to move the tags based on the mouse position.

Step 3: Rendering the Tags on the Screen 🖥️

tags.forEach((tag) => {
  const scale = fov / (fov + tag.vectorPosition.z);
  tag.element.style.transform = `translate(${tag.vectorPosition.x * scale}px, ${
    tag.vectorPosition.y * scale
  }px)`;
});

The perspective projection ensures that tags closer to the viewer appear larger, and those farther away appear smaller.

Use CSS to customize the appearance further:

#tag-cloud {
  display: flex;
  justify-content: center;
  align-items: center;
  background: radial-gradient(circle, #1e1e1e, #000);
  border-radius: 10px;
  padding: 20px;
  box-shadow: 0px 0px 20px rgba(255, 255, 255, 0.1);
}

This gives it a sleek, futuristic look! ✨
