When I utilize an octree, I am able to generate an array of faces that are in close proximity to an object. However, I am unsure how to perform a ray cast to these faces. All the resources I have found only explain how to ray cast to a mesh, line or point. Can anyone provide guidance on this issue?
In the case that you are utilizing threeoctree, here is what you need to do:
// Locate the faces through octree search
var octreeObjects = this.octree.search( raycaster.ray.origin, raycaster.ray.far, true, raycaster.ray.direction );
// Identify intersections only within the located faces
var intersections = raycaster.intersectOctreeObjects( octreeObjects );
