interface Intersection {
object: Object3D;

Properties

distance: number

primitiveIndex: number

primitive of the intersection for indexed geometry, it related to index buffer for non-index geometry, it is related to position buffer

distanceToRay?: number

index?: number

use primitiveIndex instead only exist when hit points or lines the value maybe confused, not recommended to use

face?: Face3

faceIndex?: number

use primitiveIndex instead only exist when hit mesh

instanceIndex?: number
