Class: BoundingSphere
A bounding sphere is a volume for facilitating fast intersection testing.
Constructors
new BoundingSphere()
new BoundingSphere(center?: Vec3, radius?: number): BoundingSphere
Creates a new BoundingSphere instance.
Parameters
center?
Vec3 = ...
The world space coordinate marking the center of the sphere. The constructor takes a reference of this parameter.
radius?
number = 0.5
The radius of the bounding sphere. Defaults to 0.5.
Returns
Example
// Create a new bounding sphere centered on the origin with a radius of 0.5
const sphere = new BoundingSphere()
Properties
center
readonly center: Vec3;
Center of sphere.
radius
radius: number
The radius of the bounding sphere.
Methods
intersectsBoundingSphere()
intersectsBoundingSphere(sphere: BoundingSphere): boolean
Test if a Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere.
Parameters
sphere
Bounding Sphere to test.
Returns
boolean
True if the Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere and false otherwise.
intersectsRay()
intersectsRay(ray: Ray, point?: Vec3): boolean
Test if a ray intersects with the sphere.
Parameters
ray
Ray to test against (direction must be normalized).
point?
If there is an intersection, the intersection point will be copied into here.
Returns
boolean
True if there is an intersection.
