有没有办法从Three.js QuickHull实例获取顶点数组？

Question

我正在尝试从三个网格的快速船身创建几何，但是QuickHull实例似乎只具有与“面”相关的信息。

有没有办法从该实例获取每个顶点信息？

先感谢您。

const hull = new QuickHull().setFromObject(mesh) //Mesh is an already rendered object

//hull.vertices //this returns the entire geometry instead of the hull's vertices

是的，那应该是可能的。像这样尝试：const hull = new THREE.QuickHull().setFromObject( mesh );const vertices = [];const faces = quickHull.faces;for ( let i = 0; i < faces.length; i ++ ) {&nbsp; &nbsp; const face = faces[ i ];&nbsp; &nbsp; let edge = face.edge;&nbsp; &nbsp; do {&nbsp; &nbsp; &nbsp; &nbsp; const point = edge.head().point;&nbsp; &nbsp; &nbsp; &nbsp; vertices.push( point.x, point.y, point.z );&nbsp; &nbsp; &nbsp; &nbsp; edge = edge.next;&nbsp; &nbsp; } while ( edge !== face.edge );}如您所见，其想法是使用面的半边以正确的顺序收集所有顶点。
