Syntax

static bool SphereAABBIntersection
(
    const FVector & SphereCenter,
    const float RadiusSquared,
    const FBox & AABB
)

Remarks

Performs a sphere vs box intersection test using Arvo's algorithm:

for each i in (x, y, z) if (SphereCenter(i) < BoxMin(i)) d2 += (SphereCenter(i) - BoxMin(i)) _{2 else if (SphereCenter(i) > BoxMax(i)) d2 += (SphereCenter(i) - BoxMax(i))} 2

Returns

Whether the sphere/box intersect or not.

Parameters

Parameter	Description
Sphere	the center of the sphere being tested against the AABB
RadiusSquared	the size of the sphere being tested
AABB	the box being tested against
