Question

通过使用八叉树，我得到了靠近对象的面数组。我怎样才能向他们转换光线。我只能找到如何将光线转换到网格、线或点？

Answer 1

如果您使用threeoctree ，您执行以下操作:

// get the faces using octree search
var octreeObjects = this.octree.search( raycaster.ray.origin, raycaster.ray.far, true, raycaster.ray.direction );
// find the intersections only with the faces you found
var intersections = raycaster.intersectOctreeObjects( octreeObjects );
