Function b3RayCastHollowSphere 

pub unsafe extern "C" fn b3RayCastHollowSphere(
    shape: *const b3Sphere,
    input: *const b3RayCastInput,
) -> b3CastOutput

Ray cast versus a hollow sphere shell in local space. Unlike the solid sphere a ray starting inside is not an overlap: it passes through and hits the far wall.
