我有个问题：

我有一组 3D 点。如何在 3D 空间中绘制由顶点给出的 2D 平面对象？我想从 Points[0] 到 Points[1]，从 Points[1] 到 Points[2] 等等画线......现在我有以下解决方案：

var geometry = new THREE.BufferGeometry();

var vertices = faceToTriangles( VerticesArray );  // my function

var uvs = new Float32Array([
    0.0, 0.0,
    1.0, 0.0,
    1.0, 1.0,

    0.0, 0.0,
    1.0, 1.0,
    0.0, 1.0
]);


geometry.addAttribute( 'position', new THREE.BufferAttribute( vertices, 3 ) );
geometry.addAttribute( 'uv', new THREE.BufferAttribute( uvs, 2 ) );
var material = new THREE.MeshLambertMaterial( {color: 'red' } );
material.side = THREE.DoubleSide;
var mesh = new THREE.Mesh( …
