Sphere

AI-generated Key Takeaways

• Sphere is a mathematical representation used for intersection and collision tests.

• It provides constructors to create spheres with specified centers and radii, defaulting to (0,0,0) and radius 1 if not provided.

• Public methods allow access and modification of the sphere's center and radius.

• Sphere inherits methods from CollisionShape and Object for broader functionality.

• It's primarily used within the Sceneform library for 3D interactions and collision detection.

public class Sphere

Mathematical representation of a sphere. Used to perform intersection and collision tests against spheres.

Public Constructors

	Sphere() Create a sphere with a center of (0,0,0) and a radius of 1.
	Sphere(float radius) Create a sphere with a center of (0,0,0) and a specified radius.
	Sphere(float radius, Vector3 center) Create a sphere with a specified center and radius.

Public Methods

Vector3	getCenter() Get a copy of the sphere's center.
float	getRadius() Get the radius of the sphere.
Sphere	makeCopy()
void	setCenter(Vector3 center) Set the center of this sphere.
void	setRadius(float radius) Set the radius of the sphere.
