Additional Inherited Members
Protected Attributes inherited from MR::InSphereTesterSoS
Vector3i64	pairV_
	the fields are ordered by descending alignment to minimize the padding
Vector3i	pairPt_
	the position of the coincident pair
VertId	va_
VertId	vb_
VertId	vc_
	the ids of the sphere points given in reset()
int	pairSigma_ = 0
	the side of the limit sphere's center: +1 along ( -Vy, Vx, 0 ), -1 the opposite
bool	degenerateTriangle_ = false
	reset() got W == 0 with two coincident points and an existing perturbed sphere

Detailed Description

gives exactly the same answers as InSphereTesterSoS, only faster: the sphere's center is also computed in floating point during reset(), and every query point far enough from the sphere's surface is answered by it alone, leaving the exact predicates for the points close to it
