How does three.LineSegmentsGeometry work?

three.LineSegmentsGeometry is a class in the Three.js library that inherits from three.LineSegments. It represents the geometry for a set of line segments. It can be used to create and manipulate sets of line segments by adding positions, colors, and other attributes to the geometry. Once the geometry is defined, it can be used in a three.LineSegments object to display the line segments in a Three.js scene. Internally, the three.LineSegmentsGeometry class uses a set of arrays to store the vertex and attribute data for the line segments. This data can be accessed and modified directly using the methods provided by the class. One important thing to note is that, unlike three.BufferGeometry, three.LineSegmentsGeometry does not use interleaved attribute arrays. This means that each attribute is stored in a separate array, which can make it less efficient for large sets of line segments. Overall, three.LineSegmentsGeometry provides a convenient way to work with sets of line segments in Three.js, allowing developers to easily create and manipulate them as needed.

const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(
  75,
  window.innerWidth / window.innerHeight,
  0.1,
  1000
);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

const geometry = new THREE.LineSegmentsGeometry();

// Add positions and colors for two line segments
geometry.setPositions([0, 0, 0, 1, 1, 1, 1, 1, 1, 2, 2, 2]);
geometry.setColors([1, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 1]);

const material = new THREE.LineMaterial({
  color: 0xffffff,
  linewidth: 2,
  dashSize: 0.1,
  gapSize: 0.1,
});

const lines = new THREE.LineSegments(geometry, material);

scene.add(lines);

camera.position.z = 5;

function animate() {
  requestAnimationFrame(animate);
  lines.rotation.y += 0.01;
  renderer.render(scene, camera);
}

animate();

In this example, we create a three.LineSegmentsGeometry object with two line segments, and add positions and colors for each segment using the setPositions() and setColors() methods. We then create a three.LineMaterial and a three.LineSegments object using the geometry and material, and add the lines to the Three.js scene. Finally, we set the camera position and start an animation loop that rotates the lines around the y-axis. When you run this code, you should see two colored, dashed lines rotating on the screen.
