BoundingSphere class

A sphere defined by a center and radius.

Constructors

BoundingSphere.new([Vector3? center, double? radius])

center - center of the sphere. Default is a Vector3 at (0, 0, 0).

BoundingSphere.copy(BoundingSphere sphere)

Copies the values of the passed sphere's center and radius properties to this sphere.

Properties

center ↔ Vector3

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

radius ↔ double

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

applyMatrix4(Matrix4 matrix) → BoundingSphere

matrix - the Matrix4 to apply

clone() → BoundingSphere

Returns a new sphere with the same center and radius as this one.

containsPoint(Vector3 point) → bool

Returns true if this sphere contains the given point inclusive of the surface of the sphere.

empty() → BoundingSphere

Makes the sphere empty by setting center to (0, 0, 0) and radius to -1.

expandByPoint(Vector point) → BoundingSphere

point - Vector3 that should be included in the box.

intersectsBox(BoundingBox box) → bool

box - page:Box3 to check for intersection against.

intersectsPlane(Plane plane) → bool

plane - Plane to check for intersection against.

isEmpty() → bool

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

set(Vector3 center, double radius) → BoundingSphere

center - center of the sphere.

setFrom(BoundingSphere sphere) → BoundingSphere

Copies the values of the passed sphere's center and radius properties to this sphere.

setFromPoints(List<Vector3> points, [Vector3? optionalCenter]) → BoundingSphere

Computes the minimum bounding sphere for list of points. If the optional center point is given, it is used as the sphere's center. Otherwise, the center of the axis-aligned bounding box encompassing the points is calculated.

toString() → String

A string representation of this object.

inherited

union(BoundingSphere sphere) → BoundingSphere

sphere - Bounding sphere that will be unioned with this sphere.

Operators

operator ==(Object other) → bool

The equality operator.
