findAllIntersectedSpheresOrderedByDistanceToRay(ray: Ray, radius: number, pointsArr: ArrayLike): { index: number, l2Distance: number }[]

Find all the points (spheres) intersected by the ray, and return them ordered by the distance to the Ray (closest first).

The spheres are defined with a radius and an array of points in the pointsArr array

The pointsArr array contains a number of sphere centers in a 1d array: <s1.x, s1.y, s1.z, s2.x, s2.y, s2.z> …

Parameters

ray: Ray

radius: number

pointsArr: ArrayLike

Returns: { index: number, l2Distance: number }[]

static cee.RaySphereIntersector.findClosestIntersectedSphereToRay()

static

findClosestIntersectedSphereToRay(ray: Ray, radius: number, pointsArr: ArrayLike): number

Returns the index of the closest intersected sphere to the ray
