BoundingSphere

A bounding sphere is a volume for facilitating fast intersection testing.

// Create a new bounding sphere centered on the origin with a radius of 0.5
const sphere = new pc.BoundingSphere();

Summary

center	Center of sphere.
radius	The radius of the bounding sphere.

intersectsBoundingSphere	Test if a Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere.
intersectsRay	Test if a ray intersects with the sphere.

Creates a new BoundingSphere instance.

// Create a new bounding sphere centered on the origin with a radius of 0.5
const sphere = new pc.BoundingSphere();

center	Vec3	The world space coordinate marking the center of the sphere. The constructor takes a reference of this parameter.
radius	number	The radius of the bounding sphere. Defaults to 0.5.

Vec3center 

Center of sphere.

numberradius 

The radius of the bounding sphere.

Test if a Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere.

sphere

Bounding Sphere to test.

True if the Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere and false otherwise.

Test if a ray intersects with the sphere.

ray	Ray	Ray to test against (direction must be normalized).
point	Vec3	If there is an intersection, the intersection point will be copied into here.

True if there is an intersection.
